  • Storm Water Management Report
  • Arborist Report
  • Landscape Architect Plan
  • Architectural Drawings

  • Heat Gain Calculations and Cooling Design
  • Duct Sizing
  • Ventilation Design including Heat Recovery Ventilator
  • Submission of Plans, Drawings & Reports to municipal authorities for Review and
    Revision of Drawings to obtain building permits
  • Verification for Construction Compliance

If the property is covered by a site plan control by-law, building permit for the proposed
addition will not be issued until the plans and drawings for the proposed addition have
been approved by the municipality. In addition to the planning approval and building
permit which are required for an addition, other permits and approvals including
Conservation Authority may be required.

Zoning by-law rules that apply to the property must be determined during the preliminary
planning stage of the addition.  Municipal Zoning by-laws regulate the use, size, location
and types of additions permitted on property. The Municipal By-law contains a wide array
of land use and development regulations that must be met before an addition erected.
The regulations address such matters as:
  • Setbacks of addition from the property lines
  • Setbacks of proposed addition from lands zoned hazardous
  • Height of proposed addition
  • Floor areas of proposed addition
  • Lot coverage (usually a maximum percentage of the lot that may be covered)

The Official Plan outlines in a broad manner the land use and development guidelines
within a municipality. A Zoning By-law, on the other hand, outlines how a specific parcel of
land may be used. Zoning By-laws also regulate lot size, parking requirements, building
height and other site-specific factors. A site-specific amendment to the By-law through a
Zoning By-law Amendment application (commonly called a rezoning) is required for any
development  that does not conform with the Zoning By-law.or any  renovation  that
deviates from the current zoning provisions. Since the Zoning Bylaw implements the
Official Plan, a proposed Zoning Bylaw amendment must still conform to the Official Plan.
If it does not, the proposed Zoning Bylaw amendment may not be appropriate without first
obtaining an Official Plan amendment.

Section 34 of the Planning Act grants the municipal authority to implement land use
controls through Zoning By-laws. The Zoning By-law is the legal document that
implements policies and objectives described in the Official Plan and regulates the use
and development of buildings and land by: Stating exactly what types of uses are
permitted in various areas.  

To ensure the municipal interests are met and to appropriately assess the merits and
technical aspects of the proposal, the municipality requires submission of a number of
information items with the Zoning By-law Amendment (rezoning) application. A pre-
application consultation meeting is recommended to assist in determining the
requirements that must be provided as part of the initial Zoning By-law Amendment
(rezoning) application submission in order for it to be considered a complete application.

The municipality will endeavour to review the Zoning By-law Amendment (rezoning)
application and render a decision within the target timelines. The municipality's
commitment to the target timelines will only begin once a complete Zoning By-law
Amendment (rezoning) application submission is received. The level of detail required for
most of the reports/studies  can vary, depending on the nature of the property and the
proposal. In some cases, a single-page letter from a qualified expert will be adequate,
while in other situations a major study will be necessary. The requirement and scope of
any reports/studies can be assessed during the pre-application consultation meeting.

All properties subject to a zoning by-law amendment are required to post a Notice of
Application sign or signs on the property affected by the application.

When a building permit application is made for an addition, the Municipal Building
Department staff will make a comparison between the proposed addition and the minimum
development requirements set out in the municipal zoning by-law. If one or more
municipal zoning by-law requirements cannot be met and it is not possible to revise the
proposed addition to fully conform to the municipal by-law, you are provided the option of
seeking minor variance approval. If all provisions of the municipal by-law are met no minor
variance approval is required and you may proceed to the next step in the building permit
application process for the addition.

A Minor Variance provides approval for the proposed addition that does not fully comply
with the Municipal Zoning By-law. A Minor Variance will not change the Zoning By-law, it
merely grants a relief from certain existing provisions/standards of the By-law, where
appropriate for the proposed addition. Minor Variances are heard by the Committee of
Adjustment. The Committee of Adjustment is made up of individuals from the community
who are appointed by the Municipal Council. The Committee of Adjustment meets monthly
to consider Minor Variance applications. The Planning Act directs that the Committee of
Adjustment must be satisfied that an application for a minor variance on four points — that
the variance requested maintains the intent and purpose of the Official Plan and Zoning
By-law; that it is considered desirable for the appropriate and orderly development or use
of the land; and that the variance(s), in the view of the Committee is truly minor in nature.
The Committee of Adjustment operates as a quasi-judicial tribunal in accordance with the
authorization granted to it under the Planning Act.  The Planning Act directs the
Committee of Adjustment with respect to the scope of its authority; the considerations that
it must have when making any decision on an application presented to it; and the
administrative provisions it must comply with regarding notice of Minor Variance
applications and hearing procedure. The following information is typically required for
Minor Variance Application:
  • Owner's Name,  Address, Email, Telephone
  • Name and Address of the holders of any mortgages
  • Legal description of the Property & Property Tax Roll Number
  • Lot Frontage, Lot Depth &  Lot Area
  • Any easements or restrictive covenants affecting the property
  • Existing land use:
  • Type of Existing Structure
  • Date Constructed, Height and Floor Area
  • Front Lot Line, Rear Lot Line and Side Lot Line Setbacks
  • Date the subject land was acquired by the current owner
  • Date of construction of existing buildings/structures
  • Length of time the existing uses of the subject land have continued
  • Proposed Changes
  • Height and Floor Area of the proposed addition
  • Front Lot Line, Rear Lot Line and Side Lot Line Setbacks for the proposed addition
  • Current Zoning:
  • Nature and extent of the relief requested from the Zoning By-law
  • Explanation why it is not possible to comply with the provisions of the Zoning By-law:
  • Current Official Plan designation(s) of the subject land:
  • Services are available & proposed: Water Supply, Sewage Treatment, Storm Drainage
  • Does the site or adjacent lands include any significant trees or other natural features?
  • Is the site adjacent to any significant source of noise or vibration?
  • Are there any outstanding work orders on this property?
  • Is there an existing Site Plan Agreement for this property?
  • Has there been filling on the site or subject land?
  • Is there reason to believe that the site may have been contaminated by former uses on
    the site or adjacent sites?
  • Any recent environmental site assessment reports available?
  • Does a legal and adequate outlet for storm drainage exist?
  • Has the existing drainage on the subject land been altered?
The Minor Variance application under Section 45(1) or application for permission under
Section 45(2) of the Planning Act must include a detailed sketch (in metric units) showing
the following information (in some cases it may be appropriate to combine with a survey
plan). Wherever possible, a digital file as well as paper copies of the plan is required.
Plans must be submitted with the following information:
  • boundaries and dimensions of the subject land;
  • the location, size and type of all existing and proposed structures on the subject land,
    indicating their distance from the front lot line, rear lot line and side lot lines;
  • the approximate location of all natural and artificial features (buildings, roads, drainage
    ditches, wooded areas etc) that are located on the subject land and on land that is
    adjacent to it, and in the applicant’s opinion, may affect the application;
  • the current uses of land that is adjacent to the subject land;
  • the location, width and name of any roads within or abutting the subject land,
    indicating whether it is an unopened road allowance, a public travelled road, a private
    road or a right of way; and,
  • the location and nature of any easement affecting the subject land.

A Notice of Hearing Sign for your minor variance application under Section 45(1) or
application for permission under Section 45(2) of the Planning Act will be provided by the
Secretary-Treasurer of the Committee of Adjustment.

This sign must be posted at least 10 days before the actual meeting date in order to
comply with the requirements of the Planning Act. The sign must be attached to a stake
and put in the ground in the boulevard in front of the property so that it is clearly visible
from the road. (Do not post sign on a tree or in a building).

Once the sign has been posted the municipality must be notified.
Failure to comply will result in the application being tabled until the next available meeting
and until the sign is posted and the applicant has complied with the requirements of the
Planning Act. Remove the sign 21 days after the Committee has made a decision on the
site plan application.

Site Plan
Typical Site Plan may include the following:
  • Locations of all existing trees and proposed landscaping details.
  • Location and dimensions of all existing and proposed structures
  • Proposed parking layout and dimensions of parking spaces
  • All existing underground municipal services and utilities

Site Plan Approval
Once the site plan application form is completed, with the necessary information
assembled, the Municipality will circulate the submission to various departments and
agencies. The comments from these sources are then compiled to allow completion of the
Schedules which will form part of a Site Plan Agreement which must be approved by
Council. If approved by Council, the Site Plan Agreement is registered on title of the
property and is binding on all owners. Amendment to the Agreement can occur only with
Council approval. The final Agreement will consist of written text (the Agreement) which
will refer to and therefore include the following Schedules:
  • the Site Plan;
  • the Building Elevations Plans (all sides);
  • the Landscape Plan;
  • and may include reference to any specialized studies considered necessary to the
    municipality in the review of an application. Such studies may include an
    Environmental Impact Study (EIS); land use compatibility study; a hydrogeological
    and/or geotechnical assessment;  a lake impact study; archaeological report or
    another form of analysis used to ensure that a proposal will not result in negative
    impacts to the public or the environment, amongst other factors.

The Site Plan Agreement will include provisions for a performance guarantee, impost fees,
timing of construction, and payment of costs.

Site Servicing Plan
A Site Servicing Plan showing all internal site services for storm, sanitary and water is
required for approval prior to final site plan approval for an addition. The Site Servicing
Plan must also show the location of all service structures or cleanouts so that the
municipality may assess the impact a particular site may have on the municipal system.
The municipality must be satisfied that proper engineering practices have been applied to
the design of all services within the site and within the Right-of-Way.

The site servicing plan typically includes the entire site, as well as the street frontage(s) to
at least the centerline and beyond to the furthest utility service to which a site connection
is to be made.  The site servicing plans show all existing surface and underground
infrastructure including sewer, drain and water services (sized), curbs, sidewalks,
boulevards, driveway crossings with dimensions from property lines; trees, hydrants,
boulevard services, utility poles, lamp standards, signs; under sidewalk basements;
sewer, drain, water mains, gas, hydro electric, telephone and fibre optic ducts, overhead
wiring; manholes, hydro and telephone vaults, water valves, meter boxes; lateral
connections and  catch basins;

The site servicing plans also show all proposed buildings and services, fully dimensioned,
including municipal connections like water, sewer and drain services (sized); proposed
and redundant driveway crossings; complete with dimensions to trees, hydrants,
boulevard services, utility poles, lamp standards, signs; proposed on-site driveway grades;
plan and profile of proposed road, curbs, sidewalks, and boulevards; critical access points
(ie. doorways) with transitions, grades and sections; landscaping (new trees, grass,
irrigation systems, hard landscaping, etc.) on-site surface drains; hydro electric services
(overhead or underground); gas service; telephone service (overhead or underground);
and fibre optic ducts.

Our Licensed Professional Engineers specializing in Site Grading offer Site Grading and
Erosion Control Plans to obtain site plan approval and building permits for additions in
Ontario including City of Toronto, Durham Region, Halton Region, Peel Region and York
Region (Ajax, Aurora, Bolton, Brampton, Burlington, Caledon, Etobicoke, Halton Hills,
Maple, Markham, Milton, Mississauga, Newmarket, North York, Oakville, Oshawa,
Pickering, Richmond Hill, Scarborough, Stouffville, Toronto, Vaughan, Uxbridge, Whitby,
Barrie, Bowmanville, Clarington Hamilton, Georgetown, Georgina, Guelph, Milton,
Stoneycreek, and Woodbridge).

The Site Grading and Erosion Control Plan prepared by our licensed professional
engineers specializing in Municipal engineering will illustrate how the site will be graded to
provide erosion protection during the construction of the addition; how the final grading
will ensure positive drainage away from the addition; how the rainfall runoff will be directed
to an approved outlet; and that the site grading is compatible with the neighbouring
properties. The site grading plan is to be implemented in a fashion to allow stormwater
management to be implemented using both the minor and major drainage systems.
Improper grading of the lot can result in poor surface drainage, ponding or flooding
around the basement wall, foundation settlement or other damage, and basement
dampness and other undesirable effects.

Site Grading Plan typically includes the following:
  • General Details - All property lines, Ground floor plan for the proposed addition, if
    applicable all easements, and reserves.
  • Parking and Driveways and all adjacent roads and sidewalks
  • Public & Private Servicing Information The location of proposed utilities,gas regulators
    on the site and on adjacent road allowances
  • Landscaping, Grading & Retaining Walls and Lighting  - All retaining walls  General
    grading information including the existing and proposed elevations at 6 m intervals
    along property lines, driveways, sidewalks and walkways and trees to be preserved,
    including all trees on adjacent properties within 6 m of subject site’s property/lot lines
    Proposed elevation at 6m intervals along all building and structure perimeters and
    building entrances Storm and surface water drainage directions, site ponding limits
    with corresponding control volumes and control facilities, major overland and
    emergency overland flow routes Soil retention and/or replacement details
  • Sediment and erosion control measures applied during construction Location and
    identification of trees protected under municipal by-laws
  • Location of tree protection zones (where trees are being retained & protected) Tree
    protection plan notes (where trees are being retained & protected) Buried
    watercourses, if applicable

An apron of no less than 2% slope, and a minimum width of 2 to 4m are required around
all building envelopes.  In areas where the soils have a minimum percolation rate of
15mm/hour, and the swales are being implemented as a storm water quality management
feature, the minimum slope may be reduced to 1% in some areas. Swales to be designed
to convey the 4hour-25mm Chicago storm and maintain a velocity less than or equal to 0.5
m/s. The treatable flow length must be maximized to provide for proper pre-treatment of
flows. Check dams should be implemented to enhance pre-treatment and provide
additional infiltration for baseflow enhancement, where applicable. The following standard
notes are placed on the Grading and Erosion Control Plan along with the erosion control
•        All silt fencing to be installed prior to commencement of any area grading,
excavating, or demolition.
•        Erosion control fencing to be placed around the base of all stockpiles. All stockpiles
to be kept a minimum of 2.5m from all property lines.
•        Erosion protection to be provided around all storm and sanitary manholes and/or
catchbasins as per the attached details.
•        Additional erosion control measures may be required as site development
progresses. Contractor to provide all additional erosion control structures.

Name) and any damage repaired immediately. Sediments to be removed when
accumulations reach a maximum of one third (1/3) the height of the silt fence.
•        No alternate methods of erosion control protection shall be permitted unless
approved by the Municipality
•        The Contractor is responsible for removing sediments from the municipal roadway
and sidewalks at the end of each work day
•        All erosion control structures to remain in place until all disturbed ground surfaces
have been re-stabilized either by paving or restoration of vegetative ground cover.
•        Mud mats to be provided on site at all locations where construction vehicles exit the
site. Mud mats shall be a minimum of 3m wide, 15m long (length may vary depending on
site layout) and 0.3m deep and shall consist of 200mm clear stone material or approved
equivalent. Contractor to ensure all vehicles leave the site via the mud mat and that the
mat is maintained in a manner to maximize its effectiveness at all times.
•        Owners Representatives to monitor the site development to ensure all erosion
controls are installed and maintained to Municipal requirements.
•        Contractor to comply with the Engineer's instructions to install, modify, or maintain
erosion control works.
•        The property owner is responsible for restoration of all damaged and/or disturbed
property within the municipal right-of-way to Municipal standards.
•        If, for unforeseen reasons, the Owner and/or his/her representative must encroach
onto private lands to undertake any works, he/she must obtain written permission from the
adjacent property owners prior to entering upon the private property to perform any works.
Copies of these letters of consent must be submitted to the Municipality prior to any work
being performed. Failure to comply with the above is at the property owners own risk.
•        Each Grading and Erosion Control Plan shall bear a note making reference to all
other plans included with the Storm Water Management Report. Reference should also be
made to the Storm Water Management Report itself, the date of the report, and the
Landscaping Plan (e.g. This plan to be read in conjunction with the Existing Conditions
Plan, Site Servicing Plan), Storm Water Management Plan, Landscaping Plan, and the
Storm Water Management Report.
Proper site grading plans are prepared to fit within the constraints of the lot, creating cost-
effective site specific plans to meet city, town, county and /or region requirements. The
Site Grading and Erosion Control Plan prepared by our licensed professional engineers
specializing in Municipal engineering will illustrate how the site will be graded to provide
erosion protection during the construction phase; how the final site grading will ensure
positive drainage away from all buildings; how the rainfall runoff will be directed to an
approved outlet; and that the site grading is compatible with the neighbouring properties.

Stormwater refers to rainwater and melted snow that flows over roads, parking lots, lawn
and other sites. Under natural conditions, stormwater is intercepted by vegetation and
then absorbed into the ground and filtered and eventually replenishes aquifers or flows
into streams and rivers. Later, part of it is returned to the atmosphere in the form of
evapotranspiration. When an area is converted from a natural area to an urbanized area,
due to the addition of hard (impervious) surfaces, the volume of water that runs off the
land increases. In urbanized areas impervious surfaces such as asphalt pavements and
roofs prevent precipitation from naturally soaking into the ground. Instead, the water runs
rapidly into storm drains, municipal sewers and drainage ditches into streams, rivers and
lakes and on its way it picks up pesticides, road salts, heavy metals, oils, bacteria, and
other harmful pollutants and transports them through municipal sewers into streams,
rivers and lakes.
Stormwater runoff is different from wastewater, which flows into sanitary sewers from
household drains.
The sheer force and volume of polluted runoff causes:
•        Increased downstream flooding risks
•        River bank and bed erosion
•        Increased turbidity
•        Aquatic Habitat destruction
•        Changes in the stream flow regime
•        Combined sewer overflows
•        Infrastructure damage
•        Contaminated streams, rivers,and lakes.
In order to mitigate the undesirable impacts of urbanization on watercourses and
associated infrastructure stormwater management practices need to be implemented:
•        To preserve the natural hydrologic balance in newly developing areas and re-
establish it, wherever possible, in already developed areas;
•        To protect and enhance quality of stormwater discharged to lakes and streams; and
•        To reduce the volume and frequency of combined sewer overflows in older urban
Rapid urban expansion and associated construction activities are a significant source of
stress to the natural environment.  Construction activities accelerate natural processes of
erosion and sedimentation as vegetation is stripped away and soils are left exposed.  
Consequently, stormwater runoff from these sites contains high levels of sediment and
associated contaminants.  Implementation of adequate water quality controls at
construction sites is crucial to ensuring downstream receiving waters and aquatic habitats
are adequately protected.

Stormwater management involves storing and directing stormwater runoff in urbanized
areas to control flooding, erosion and water quality. This practice protects communities,
municipal infrastructure (like roads, sidewalks and trails) and local waterways. The
objective of stormwater management is to slow the release of stormwater runoff into
natural systems.

Soak-away pits/infiltration trenches are to be incorporated into the storm water
management design where the geotechnical report indicates the subsurface soils have a
minimum percolation rate of 15mm/hr. The volume of the gallery will be designed to hold
the 25mm storm over the entire proposed roof area.  In order to assess feasibility of
infiltrating roof runoff, boreholes or test pits must be drilled/excavated (minimum of 5m
below grade).  All soak-away pits/infiltration galleries are to have a minimum of two
observation wells (for inspection/maintenance purposes). A minimum cover of 1.2m is
required for all infiltration facilities to protect against frost penetration. A minimum of 1m is
required for separation from the bottom of the infiltration facility to the high ground water
level. The high ground water level must be identified on the detail. All soak-away
pits/infiltration galleries must have an overflow system.

One way of managing stormwater runoff is through the use of stormwater ponds.
Stormwater ponds can be ‘dry’- filling up during a storm, or ‘wet’- having a permanent pool
of water. These ponds are designed to hold back stormwater and release it slowly to
natural waterways. Wet ponds also allow sediment to settle to the bottom of the pond
instead of traveling to a local stream. Stormwater management ponds are so well
integrated into the landscape that too many people they appear to be natural ponds.
However, they do require maintenance to keep them working properly, such as sediment
removal or cleaning of catchbasins. Sometimes older ponds need to be replaced with
newer, more efficient designs.

Without stormwater management, runoff from urbanized areas would flood communities
and roads, cause stream erosion and destroy aquatic habitat. In August of 2005, the City
of Toronto experienced a major storm event which resulted in the collapse of part of Finch
Avenue West. The storm was so intense that the Black Creek culvert under Finch Avenue
West was unable to handle the amount of runoff flowing through it.

More recently, the south end of Don Valley Parkway was flooded in May of 2013. The Don
River overflowed its banks and spilled onto the Don Valley Parkway. This caused major
delays for the morning commute. Runoff from this storm also caused basement flooding in
many homes.

On July 8, 2013, a record breaking 126mm of rainfall was recorded at Pearson
International Airport within a 24hour period. This was more rainfall than Hurricane Hazel in
1954. This extreme rainfall event cause the closure of highway ramps, parks, and offices,
it flooded streets and basements and caused major electrical outages in certain parts of

Lakes and local streams also suffer from runoff. Stormwater that rushes uncontrolled from
urban pavements causes streams to rise faster and more dangerously than those in rural
areas. The force of the water during rain events scours stream bottoms, erodes banks,
harms fish habitat and increases pollutants such as phosphorus and heavy metals.
Stormwater picks up dirt, oil, grease, road salt, fertilizers, pesticides and bacteria from
urbanized areas. During its journey over pavements, stormwater also becomes warmer
which is harmful to fish.

Stormwater management is required to release runoff into natural waterways slowly,
imitating the water cycle before urbanization. Stormwater ponds are also important
because they provide an opportunity for sediment (and pollutants attached to the
sediment) to become trapped in the pond bottom, rather than moving into the local

Low Impact Development is a stormwater management strategy that seeks to mitigate the
impacts of increased runoff and stormwater pollution. Low Impact Development comprises
a set of site design strategies and distributed structural best management practices that
harvest, filter, evapo-transpire, detain and infiltrate stormwater.
Low Impact Development Principles
•            Integrate Stormwater into Planning (Multi Disciplinary Approach)
•            Focus on runoff prevention (innovative planning, LID practices)
•            Treat stormwater at the source as a resources (respect natural flow paths)
•            Create multifunctional landscapes (site aesthetics, energy, conserve potable
water, wildlife, parks)
•            Educate and maintain (legal agreements, maintenance plans)

Stormwater Management Report evaluates the effects on the stormwater and drainage
system, and to recommend how to manage rainwater and snowmelt, consistent with the
Municipal Wet Weather Flow Management Policy and while also meeting regional,
provincial and federal regulations. The level of detail for the Stormwater Management
Report depends on the type and scope of application, the size of the development and the
types of stormwater management schemes proposed. For example, a Stormwater
Management Report for a Plan of Subdivision will typically be more complex than a
Stormwater Management Report in support of a Site Plan Control application. A
Stormwater Management Report is typically required for the following application types:
•        Zoning By-law Applications
•        Plans of Subdivision
•        Plans of Condominium
•        Consent to Sever
•        Site Plan Control applications

Heat Loss and Duct Design Layout are required on all new construction  

We offer
Heat Loss & Gain Calculations to Determine Building Loads - Proper load calculations are
required to prevent  wrong sized HVAC systems causing higher energy bills,reduced life-
span of the HVAC system and discomfort for occupants.
Duct Sizing Calculation - To determine the appropriate size and layout of ducts based on
their application  and their position (main or branch ducts) to provide the perfect space
through which ample heated and cooled air can flow to keep the occupants comfortable
without overworking the HVAC system.
Design Heating, Ventilation and Air Conditioning (HVAC) systems - Our design engineers  
ensure that energy efficiency is consistent with the budgets and usage of the building -
Inappropriately designed HVAC systems may contribute excessive energy consumption
and/or discomfort to the occupants of the building.
Design of Plumbing and Drainage Systems -  We design/coordinate the appropriate type,
number and placement of the plumbing fixtures in the different areas of the building. To
economically design a sanitary drainage system, we use the smallest pipes possible that
can rapidly carry away the soiled water from individual plumbing fixtures without clogging
the pipes, leaving solids in the piping, generating excessive pneumatic pressures at points
where the fixture drains connect to the stack and creating undue noise.
Sustainable Design Alternatives - We provide input about green approaches early in the
design process, designing more efficient, sustainable and better-sized mechanical

Once a complete application for a Building Permit is submitted to the city, the application
will reviewed by Building & By-law staff who assess the application for compliance with the
municipal zoning by-law, conformity with the Ontario Building Code, service connections,
and any other factors which might apply to the specific project. We promptly respond to
requests for information by Municipal Building & By-law staff to avoid unnecessary delays
in obtaining the Building Permit. Once a complete application for a Building Permit is
received, it usually takes 2 to 4 weeks to review plans by the Municipal Building & By-law
staff and prepare a building permit for issuance, depending on the project. The Building
Permit will be issued when all necessary approvals have been obtained and fees for the
Building Permit have been paid to the municipality. The Building Permit must be posted in
plain view on the construction site for the municipal building inspector to verify at all times.

Construction Compliance & Review
It is the owners and the contractor's responsibility to contact the Municipality to conduct
the required inspections once the construction project starts. Neglecting these inspections
may cause costly delays and time consuming work stoppages. The name and telephone
number of the Inspector or Inspections office is included with the permit documents. A
municipal building Inspector can assist in determining which inspections are required for
the particular project. Depending on the nature of the project, municipal building
inspectors may have to visit the building site several times to conduct the following
inspections. Owners and contractors are required to notify the municipal inspector once
the project reaches a point where it is ready for each required inspection. Inspections will
take place within the next two business days. The inspection is conducted using the site
copy of the stamped permit plans. The inspector must be able to see the entire building
element being inspected. Any elements which are covered before they have passed an
inspection will have to be uncovered so they can pass inspection. For any questions about
the required inspections for the project, please contact the building inspector or local
inspection office.

Co-operation of the owner or contractor is required to ensure that mandatory. Ontario
Building Code inspections are conducted during the stages of construction. Failure to
notify may require that any or all of the items to be inspected are to be exposed to the
satisfaction of the municipal inspector at a later date, and prosecution under the Ontario
Building Code Act for failure to call for required inspections.

We also provide general reviews of the construction/renovation to determine whether the
construction is in general conformity with the plans and other documents that form the
basis for the issuance of a building permit.

We charge $195 per site visit for general review and $275 per review report. All general
review reports will be forwarded promptly to the Chief Building Official.

Our commitment is to continually provide our customers the finest quality engineering
drawings at a fair and competitive price with a superior customer satisfaction.
