Commercial Permits · Mississauga, Peel Region
Commercial permits and change of use for Mississauga units and buildings: restaurant, office and retail fit-outs with the use checked against Zoning By-law 0225-2007 before you lease, storefronts in the Streetsville and Old Port Credit Village heritage districts, and fire and life-safety design, filed through ePlans.
What’s included
Commercial work is judged on the code analysis before it is judged on the drawings. We classify the occupancy, confirm the zoning and work out the fire and exit requirements first, so the layout you commit to is one the city will approve. In Mississauga the package goes to the City of Mississauga Planning and Building Department, and it is drawn to that department’s checklist.
Fit-outs & new builds
Tenant fit-outs, alterations and new commercial construction, drawn to scale with the designer’s credentials and signature the Ontario Building Code requires on commercial plans.
New occupancy
Required whenever a building’s purpose changes, even with no construction: an office becoming a restaurant, a clinic becoming a supermarket, a residential unit becoming a shop.
Opening the doors
The approvals a new business needs beyond the building permit, worked out before the lease is signed so nothing surprises you at opening.
Occupant safety
Fire alarm, sprinkler, emergency lighting and exit-sign layouts, designed with the permit package so the fire department and the building department see one set.

How it runs
Four steps, timed around your lease. We start with the code analysis so the layout you fall in love with is one the city will approve.
We measure the unit, confirm the zoning permits your use, and classify the occupancy under the Building Code. That tells us what the space needs before any layout is drawn.
Floor plan, exits, washrooms, kitchen and mechanical rooms are laid out together with your designer’s or franchisor’s standards, so the permit set and the fit-out drawings agree.
Architectural, structural, mechanical and fire-safety sheets come from one office, stamped by our P.Eng and BCIN designers.
We file the building permit and support the sign permit, fire inspection and licence applications that follow, answering city comments at no extra charge.

(416) 990-9179The City of Mississauga Planning and Building Department reviews it as a building permit application, with or without construction. Peel Region is the upper tier and plays no part in the permit itself. Outside regrading can also fall under Mississauga’s site alteration by-law, whose terms are written around residential lots, so we ask the department how it treats a commercial one.
Only when the work reaches regulated land near a watercourse, valley, wetland or floodplain in Mississauga, which Credit Valley Conservation (CVC) maps. Ontario Regulation 41/24 counts site grading, moving fill and building or enlarging a structure as development activity, so the trigger for a commercial job is outside work: a patio, an addition or new parking. Where it applies, the CVC permit comes before the building permit.
Yes. Mississauga residents apply for building permits online through ePlans, and they can check application status in the same system under Project info. We watch the status there and answer examiner comments as they come in, at no extra charge.
Yes. We take on commercial permits across Mississauga, including Port Credit and Streetsville, within an hour of our Richmond Hill office. The first consultation is free, by phone or on site.
Three things to start: unit address and the landlord’s base-building drawings, if any; what the space was used for before, and what you plan; and your lease start date and any landlord deadlines. Send those and we tell you what the City of Mississauga Planning and Building Department will ask for before we quote.
Several approvals, and the building permit is only one of them. The change of use and the fit-out go to the City of Mississauga Planning and Building Department through ePlans, and the permit can only be issued once By-law 0225-2007 allows a restaurant on that property. Food service also needs health approval, the sign needs its own permit and serving alcohol needs a liquor licence; we handle the building permit and list which of the others your unit calls for.
We answer that from Mississauga Zoning By-law 0225-2007 before you sign the lease. The by-law has been amended many times since 2007, so we read the zone and its permitted uses for the address as they stand now, then compare your use with what the unit was last approved for. Where the zone does not list your use, the Planning and Building Department holds the permit until a minor variance or a rezoning allows the use there.
Yes, with an extra step first. Streetsville, Old Port Credit Village and Meadowvale Village are Mississauga’s heritage conservation districts under Part V of the Ontario Heritage Act, and a new storefront, sign or exterior alteration inside one is held to the district’s rules. We confirm what the district asks before the elevations are drawn, so the set the Planning and Building Department reviews already fits.
Yes. Private Tree Protection By-law 0021-2022 covers trees on private property, which includes commercial land, and a tree 15 cm or more across cannot be injured or removed without a permit, even a dead one. A new patio, a wider parking area or a service trench can injure one, so we put the surveyed trees on the site plan before the layout is fixed and tell you whether a permit request should go in with the ePlans submission.
Yes, when the work alters the building. New walls, plumbing, ventilation or structural changes count as construction under Ontario’s Building Code Act whatever the use, and the application goes to the City of Mississauga Planning and Building Department through ePlans, with drawings that carry the designer’s credentials and signature. We go through your scope at the free consultation and tell you whether it needs one.
Searched & answered
Short answers to the commercial permits questions people search most, and the broader topics they lead to.
Not covered here? Book a free consultationOnly where the zoning allows the new use, or after a minor variance or a rezoning, because a building permit can only be issued for work that meets applicable law and zoning is part of it. The conversion is then a change of use permit, often with accessibility, exit and fire-separation upgrades. Fine Engineering checks the zoning before anything is drawn.
No. A building permit covers construction and changes of use under the Building Code Act. A business licence is a separate municipal approval to operate, and which businesses need one depends on the municipality and the type of business. A new restaurant or clinic can need both, applied for separately. Fine Engineering works out which ones apply to an address before the lease is signed.
The number of people a space is designed to hold under the Ontario Building Code, worked out from its use and floor area. It sets the number of exits, exit widths and washrooms and, for a bar or restaurant, the capacity on the liquor licence. Fine Engineering calculates occupant load in every commercial permit set.
It depends on the building’s size, height and occupancy, and on whether the base building is already sprinklered. A change to a higher-hazard use, such as a restaurant or an assembly space, can trigger sprinklers where none existed. Fine Engineering’s fire-safety design answers the question early, before the layout is fixed.
Yes. A restaurant is a different occupancy from an office, so the switch needs a change of use permit before any fit-out starts, and the kitchen exhaust, plumbing and fire separations go on the same application. Health approval and, where alcohol is served, an AGCO liquor licence follow separately. Fine Engineering draws the permit set and the licence plans together.
It is the building permit for work on a commercial building or unit: a tenant fit-out, an alteration, an addition or a new building. Ontario’s Building Code Act says no one may construct or demolish a building until the chief building official has issued a permit, and constructing includes materially altering an existing one. Fine Engineering prepares commercial permit sets across the GTA and Ontario.
Good to know
In Mississauga the reviewer is the City of Mississauga Planning and Building Department. Every Mississauga lot sets its own terms: the previous use of the unit, the base building’s fire separations and exits and the landlord’s own drawings decide how much the permit set has to cover.
We walk the site with the survey on a scheduled visit before anything is drawn, then file the commercial permits package to the City of Mississauga Planning and Building Department’s own checklist.
Much of Mississauga is historic village cores at Port Credit and Streetsville within 1960s to 1990s suburban neighbourhoods, with teardown rebuilds on older lots. Where a shop, an office or a clinic moves into one of the older buildings, the walls, floors and exits are measured as built first, because the upgrades a new use needs depend on what is already there and what the original permit allowed.
A building permit from the Planning and Building Department covers what you build. The Ontario Fire Code covers the building as it stands: the owner answers for it, and the municipal fire department enforces it. In the older buildings of the Port Credit and Streetsville village cores, a change of use is the time to look at both, because the exits and fire separations a new use relies on may have been built to an earlier Code.
A commercial property in eastern Mississauga along Etobicoke Creek is under the Toronto and Region Conservation Authority, not Credit Valley Conservation. On a site in a TRCA Regulated Area, outside work such as fill, regrading or a building extension needs the authority’s permit before the city can issue the building permit. An interior fit-out with no outside work does not reach that review.
