If you're choosing between a Toronto, Mississauga, Vaughan, Markham, or Richmond Hill location for your next restaurant, the city you pick can shift your opening date by six to eight weeks. At the short end of each city's typical 2026 range, Markham and Richmond Hill issue restaurant building permits in 4–6 weeks, Vaughan in 4–6, Mississauga in 4–7, and Toronto in 6–10. Here's how each city's reviewers actually behave, what they're picky about, and how a clean submission keeps your project at the short end of the range.
Toronto runs the most detail-oriented plan review in the GTA. The city's plan reviewer reads drawings closely, expects every dimension annotated, every calculation included, and every barrier-free washroom layout drawn correctly the first time. Miss any of that and the file goes back for resubmission, which adds 1–3 weeks per round.
Public health is handled by Toronto Public Health, with roughly three weeks of lead time to schedule a pre-opening kitchen walk. The fire inspector covers your fire-suppression system over the hood and the sprinkler work; on a tight downtown space, the sprinkler review is often where the calendar slips.
Things to know about Toronto: sign permits run on a separate timeline that's often longer than the building permit (8–12 weeks is common), and CafeTO patio applications run on an annual cycle that doesn't match your construction calendar. If a patio is part of the lease, plan it in early.
Toronto is the most predictable city in the GTA — but predictably the slowest. For a deeper look at the Toronto-specific path from lease to opening, see our restaurant build-out timeline from lease to opening.
Mississauga's reviewers are practical. They focus on the substantive issues — kitchen layout, exhaust, plumbing, accessibility — rather than punishing you for missing notes on the drawings. A complete submission typically clears in 4–7 weeks.
Public health is Region of Peel Public Health, who run the pre-opening kitchen walk. The fire inspector signs off on your hood suppression and sprinkler work before opening day.
Things to know about Mississauga: the city's grease and sewer rules are strict, and Peel will audit grease-trap performance on operating restaurants. The right interceptor sizing on day one avoids retrofits later. If you're building in Mississauga, our Mississauga restaurant construction page walks through the local realities.
Vaughan reviews are reasonable and fast when the package is complete. Plans go through if they're code-compliant and well-drawn; reviewers don't fight a clean submission.
Public health falls under York Region Public Health. The fire inspector handles hood suppression and sprinkler sign-off before you open.
Things to know about Vaughan: if you're going into a tower at Vaughan Metropolitan Centre, expect extra landlord scrutiny on mechanical risers and shaft routing — that's a work-letter conversation that needs to happen before drawings are stamped. For Vaughan-specific notes, see our Vaughan restaurant construction page.
Markham is one of the fastest cities in the GTA for restaurant permits, and it shows in the volume — the city's plan reviewers see hotpot, Korean BBQ, dim sum, ramen, and Asian cuisine ventilation packages weekly. They know the equipment, they know the make-up air requirements, and they don't get surprised by the things that surprise reviewers in other cities.
Public health is York Region Public Health, same as Vaughan and Richmond Hill. The fire inspector handles fire-suppression and sprinkler sign-off.
Things to know about Markham: the city is responsive to pre-application coordination, and a clean package on a familiar concept (especially Asian cuisine) often clears toward the front of the 4–6 week window. Our Markham restaurant construction page covers what we've seen across these projects.
Richmond Hill behaves much like Markham — professional, prompt, and used to restaurant TI work. Plan reviewers are responsive, and the permit office is generally willing to do pre-consultation calls when the project has anything unusual.
Public health is York Region Public Health. The fire inspector covers fire-suppression and sprinkler approvals.
Things to know about Richmond Hill: the office is small enough that early dialogue genuinely helps. A 20-minute call before you submit can save a resubmission cycle. For local context, see our Richmond Hill restaurant construction page.
These numbers assume a complete first submission with no resubmissions, drawings stamped by an architect with restaurant experience, and a contractor coordinating the package. They include drawing time, plan review, and revisions. Pre-opening kitchen and fire walks happen on top, after construction.
| City | Permit issuance | Total lease-to-permit |
|---|---|---|
| Markham | 4–6 weeks | 6–8 weeks |
| Richmond Hill | 4–6 weeks | 7–9 weeks |
| Vaughan | 4–6 weeks | 7–9 weeks |
| Mississauga | 4–7 weeks | 7–9 weeks |
| Toronto | 6–10 weeks | 10–12 weeks |
If you're deciding between two locations and the rent is comparable, the difference between a Markham permit and a Toronto permit is roughly a month of lost revenue at opening. On a 2,500 sf casual full-service concept, that's the kind of math that decides which lease gets signed.
The published timelines above assume the file is clean. Things that pull a project toward the long end of the range, in order of how often we see them:

The single biggest lever on permit speed isn't which city you're in — it's whether your submission is clean. From years of GTA restaurant work, this is the checklist we run before anything goes to a building department:
This is what our pre-construction and permit coordination service handles before drawings are submitted. It's the part of the project that decides whether you open in 12 weeks or 20.
We've worked across all five cities and built submission packages that anticipate the questions each plan reviewer asks. We aim for the short end of every city's typical range — and the way we get there is the package, not lobbying. Clean drawings, calculations included, equipment list reconciled with the electrical and mechanical packages, and the sign permit moving in parallel from week one.
For a sense of what we've put through these cities, see our project experience page.
Q: I'm choosing between a Toronto and a Markham location — which permits faster? A: Markham, by about a month. Toronto building permits typically run 6–10 weeks for restaurant TI; Markham runs 4–6. If both leases are otherwise comparable, the Markham location opens roughly four weeks sooner.
Q: Will Toronto's plan reviewer reject for a missing dimension that Markham would let slide? A: Yes. Toronto reviewers are stricter on annotation completeness — missing dimensions, missing notes, missing calculation references all draw resubmission requests. Markham reviewers focus more on whether the design itself works. Same drawings, different odds of clearing on the first round.
Q: How long does a sign permit take, and does it run with the building permit? A: Sign permits run on their own cycle, parallel to the building permit. Plan 4–12 weeks depending on the city, with Toronto on the long end. Apply the same week you submit the building permit; don't wait until construction is finishing.
Q: I want a patio in Toronto — can I add it to my building permit? A: Patios on city sidewalks go through CafeTO, which has its own annual application window and isn't part of the building permit. Plan the patio approval timeline separately from your interior build, and start it as early as the lease lets you.
Q: How much does a heritage designation slow things down? A: Heritage adds 4–6+ weeks on top of the regular building permit timeline because there's a separate heritage review. Before signing a lease in a designated building, confirm what work the heritage rules will allow on the storefront and the interior.
Q: My space already passed a previous tenant's restaurant inspection. Does that speed up my permit? A: It helps, but it doesn't shortcut the building permit. The plan review still has to happen because you're changing equipment, layout, or both. What it does help with is grease, plumbing, and electrical infrastructure already being in place — that shortens construction and reduces the questions the reviewer asks.
Q: If I submit complete on day one, can I really get a Markham permit in 4 weeks? A: On a familiar concept with a clean package, yes — we've seen it happen. The honest answer is that 4 weeks is the short end of the range, and complete drawings plus a familiar concept (especially Asian cuisine in Markham) is what gets you there.
Q: Does Buildup handle the permit submission, or just the construction? A: Both. Pre-construction and permit coordination is one of our core service buckets — we work with your architect and engineers to assemble the package, submit it to the city, and respond to plan review comments. See our FAQ for the scope of what we handle and what stays with the design team.
