Every development in the Greater Toronto and Hamilton Area (GTHA) moves through the same provincial framework: Ontario’s Planning Act. Municipalities apply it differently and add their own requirements, but the core sequence is consistent. This guide walks through the main stages in the Ontario development approval process, using the Province’s own descriptions, so landowners, builders and investors can see where a property sits and what comes next.
Step 1: Check the official plan
An official plan sets out a municipality’s general land-use policies. If a proposal does not conform, the owner applies for an official plan amendment (OPA). Council must hold at least one public meeting, with at least 20 days’ notice. After a decision, there is a 20-day appeal period; if the approval authority does not decide within 120 days, the applicant can appeal to the Ontario Land Tribunal (OLT) (Ontario.ca).
Some matters cannot be appealed, for example certain policies dealing with new settlement areas or protected major transit station areas. The Minister may also refer an official plan matter to the OLT (Ontario.ca). In larger greenfield areas, municipalities often add a secondary plan, a more detailed official plan layer for a specific community, which is itself processed as an official plan amendment.
Step 2: Get the zoning right
The zoning by-law controls the permitted uses, building heights, setbacks, densities and parking for a property. If a project does not comply, the owner applies for a zoning by-law amendment (rezoning). The applicant may appeal to the OLT if council does not decide within 90 days, or 120 days if the rezoning is filed together with an official plan amendment. Notice of passing is given within 15 days, followed by a 20-day appeal period (Ontario.ca).
Two zoning tools are worth knowing:
- Holding provisions. A holding (“h”) symbol lets a municipality zone land for its future use while delaying development until set conditions, such as servicing, are met. The holding symbol is removed by a further by-law (Ontario.ca).
- Minor variances. Small departures from zoning standards go to the municipality’s Committee of Adjustment instead of council, with a 20-day appeal period after the decision (Ontario.ca).
Step 3: Divide the land (plan of subdivision)
To create multiple new lots, a plan of subdivision is typically needed. The approval authority has 30 days to confirm an application is complete, and the applicant can appeal if there is no decision within 120 days (Ontario.ca).
If the plan is acceptable, it is draft approved with conditions such as road widenings, street naming, parkland and rezoning. Notice of decision is given within 15 days and a 20-day appeal period follows. The draft approval must include a lapse date of at least three years, which can be extended (Ontario.ca).
When the conditions are satisfied, the plan receives final approval and is registered. Lots may be offered for sale after draft approval, but they can only be sold after registration. Developers usually enter a subdivision agreement with the municipality covering services such as roads and sidewalks (Ontario.ca).
Step 4: Site plan control
For many non-subdivision projects, such as apartments, commercial and industrial buildings, the key municipal review is site plan control. Under the Province’s guide, site plan control lets a municipality review matters such as building location, landscaping, grading, drainage, access, parking and waste storage, and may involve an agreement to secure those features (Ontario.ca).
Step 5: Pay the charges
Growth-related costs are funded largely through development charges under the Development Charges Act, 1997. A municipality must pass a development charge by-law, supported by a background study, to collect them. Other tools include parkland dedication and, for some higher-density projects, community benefits charges. The Province’s guide notes that community benefits charges are capped at 4 per cent of land value and apply to buildings of five or more storeys with 10 or more residential units (Ontario.ca).
Step 6: Building permit
Once planning approvals are in place and the required agreements and fees are addressed, the project proceeds to building permits under the Ontario Building Code and construction. Planning approval and building permission are separate systems: a property can be fully zoned and still need a permit review before any construction.
Appeals and the Ontario Land Tribunal
The OLT was established on June 1, 2021 and hears appeals on many planning matters. Third-party appeal rights have been narrowed in recent years. Tribunal proceedings often start with a case management conference, and mediation may be offered. The Province’s guide notes a reduced filing fee of $400 for certain appellants (Ontario.ca). Appeal periods throughout the system are usually 20 days from the notice of decision, which is why a decision is not truly settled until that window closes.
Minister’s Zoning Orders
The Minister of Municipal Affairs and Housing can make a Minister’s Zoning Order (MZO), which zones land directly. MZOs cannot be appealed, and an order can remove site plan control requirements (Ontario.ca). They are used selectively and are not a standard route for most owners.
How the steps fit together
- Policy: official plan, and often a secondary plan, set what is allowed in principle.
- Zoning: sets the specific rules, sometimes with a holding symbol.
- Subdivision: draft approval with conditions, then registration.
- Site plan: detailed design review for many built forms.
- Charges and agreements: development charges, parkland, subdivision and site plan agreements.
- Permits: building permits, then construction.
Steps often overlap. Applications are commonly filed together, for example an official plan amendment alongside a rezoning and a draft plan, and municipalities may require pre-consultation before an application is considered complete.
Keep an eye on legislative change
The rules shift frequently. For example, Bill 140, introduced October 27, 2026, would change appeal rights where the Minister has referred official plan matters to the OLT (Environmental Registry of Ontario). Always confirm the current law and the municipality’s current requirements before relying on any timeline.
