What Is a Site Plan Application? Definition, Timing and Why Trades Watch It

A site plan application is the request a developer files with an Ontario municipality to approve how a building sits on its lot: footprint, access, parking, servicing and landscaping. It comes before the building permit, usually after any rezoning. Builtie reads Toronto's site plans and found them filed a median of 48.8 months before the permit for new buildings of $10M or more.
The same four steps, whether the buyer is a builder, a designer, an owner or a company you want to acquire.
What a site plan decides
Where the building stands on the lot, how cars and trucks get in, where parking, loading and garbage go, how water drains, and what is planted. It does not approve the construction drawings: those are checked when the building permit is applied for. In Toronto a site plan is required for most buildings beyond a house, and the City publishes every application in its open data.
Why it matters for a trade
A site plan is too early to bid but the right time to learn who is building. The developer is known, the scale is set, and the general contractor is often not chosen yet. The trade's own window comes much later: on Builtie's current windows electrical is bought at 15% to 35% of the build and drywall at 25% to 45%, both after the permit.
A real example from Builtie's data
8 Elm St, a 69-storey mixed-use building, 819 units: rezoning filed July 2016, site plan filed September 2021, building permit applied for October 2022 and issued March 2026. The site plan was public four and a half years before the permit was issued.
Where it applies
Site plan control is an Ontario planning tool; other provinces and US cities have similar reviews under other names (development permit, site development review). Builtie holds site plans for Toronto and several GTA municipalities. The measured lead time is Toronto's only.

The definition says what the term is first and why it matters to a trade second; counts are dated and come from Builtie's own records, never from an estimate of the whole market.

Frequently asked questions
Is a site plan the same as a building permit?
No. A site plan approves the building's layout on its lot; the building permit approves the construction drawings and lets work start. In Toronto the site plan came a median of 48.8 months before the permit for $10M+ new buildings.
Where can I see Toronto site plan applications?
In the City of Toronto's development applications open data, and in Builtie's Coming up tab for GTA accounts, with a Watch alert when a file moves.
