Greater Toronto Area
Restaurant and food buildouts in Mississauga.
Mississauga is where most of the region ghost kitchen, commissary and food production space sits, and it is priced as GTA rather than southwestern Ontario.

Two separate approvals, two separate authorities.
A food premises in Ontario needs a municipal building permit and a public health review, and they are not the same submission. In Mississauga they go to these two:
Public health review
Peel Public Health
Serves Mississauga, Brampton and Caledon.
Their food premises page ↗Building permit
City of Mississauga Building Division
Issues the permit and carries out the building inspections.
Their permit page ↗Peel requires notice at least 14 days before a new food premises opens, and the floor plans have to be approved by Peel Public Health. Renovation involving construction also has to be reported, with notice at least 14 days before construction starts - which is earlier than most operators expect.
Verified against each authority's own published material in September 2026. Processes and requirements change, and the only answer that counts for your project is the one the authority having jurisdiction gives for your address — check both before you rely on anything here.
On the ground
What is different about building in Mississauga
Peel wants notice earlier than most
Fourteen days before opening, and fourteen days before construction starts on a renovation. Those are specific, published requirements, and a schedule that treats public health as an end-of-project step will miss them.
Multi-suite formats multiply the mechanical, not the finishes
A commissary or a ghost kitchen with several suites needs each one metered, ventilated and drained as its own premises. The shared infrastructure - exhaust, make-up air, gas capacity, the electrical service and the grease interceptor - has to be sized for the whole building at once, and that sizing is the main cost driver on the project.
GTA pricing is a real difference, not a rounding error
Our own cost model puts the Greater Toronto Area about 14% above the Kitchener-Waterloo band per square foot, on trades and lead times rather than materials. A budget carried over from a southwestern Ontario project will be short.
What it costs here
Mississauga buildout ranges, per square foot
These are the same figures our public cost calculator uses, with the greater toronto area market factor applied and a second-generation space assumed. A cold shell runs higher; an operating refresh runs lower.

A site and lease review costs nothing and is the cheapest point at which a project can still change direction. You get a realistic timeline, a preliminary cost breakdown and the risks we can already see in the building.
