A zoning bylaw amendment in Toronto follows the Ontario Planning Act process and requires City Planning review under Zoning By-law 569-2013, with a 90-day statutory clock for standalone ZBA and 120 days for a concurrent OPA and ZBA. Required studies are confirmed at the Pre-Application Consultation (PAC) stage and typically include a Planning Justification Report, Transportation Impact Study, and Functional Servicing Report at minimum.
Toronto's Zoning By-law 569-2013 is the primary city-wide instrument, but more than 240 site-specific exceptions from predecessor by-laws remain in force. Any application on an excepted site requires a dual compliance analysis. The statutory clock under the Ontario Planning Act for a standalone ZBA application is 90 days. Neither that clock nor the 120-day concurrent OPA and ZBA clock has ever been the actual approval timeline for a major Toronto application.
Heritage Preservation Services (HPS) reviews any ZBA application adjacent to properties on the City Heritage Register, adding a mandatory commenting agency to the circulation without extending the statutory period. A ZBA application that does not address the heritage adjacency trigger receives HPS comments late in the review cycle, requiring revised studies and extending the effective review by 6 to 10 weeks.
Toronto planning applications are circulated to multiple approval bodies depending on site characteristics and application type. Triggers are site-specific and confirmed at the Pre-Application Consultation (PAC) stage.
| Body | Application types |
|---|---|
| City of Toronto — City Planning Division | SPC, ZBA, OPA, Subdivision, Condominium, Consent, Variance |
| Toronto and Region Conservation Authority | SPC, ZBA, OPA, Subdivision |
| Toronto Transit Commission | SPC, ZBA |
| Heritage Preservation Services | SPC, ZBA, OPA |
| Toronto Public Health | SPC, ZBA |
| Toronto Green Standard Review | SPC, ZBA, OPA |
| Engineering and Construction Services | SPC, Subdivision |
A Toronto ZBA application requires confirming the correct approval type, completing the Pre-Application Consultation (PAC), commissioning required studies, and filing a complete application to start the 90-day statutory clock. Misidentifying the application type is the most common cause of lost time before the clock even starts.
Verify that a minor variance is not sufficient and that an Official Plan Amendment is not also required. Misidentifying the approval type restarts the clock entirely.
City Planning confirms the required application type, study scope, and whether a concurrent OPA is needed. The pre-consultation meeting is the definitive answer on what is required.
Planning Justification Report, Transportation Impact Study, and Functional Servicing and Stormwater Management Report are almost universally required. Site-specific triggers confirmed at Pre-Application Consultation (PAC) stage.
Assemble all studies, architectural drawings, and a draft ZBA amending by-law. If a concurrent OPA is required, include the OPA draft as well.
A complete ZBA application triggers the 90-day statutory clock. A combined OPA and ZBA triggers the 120-day clock. An incomplete application is returned with no clock started.
City Planning circulates to all triggered agencies simultaneously. Upper-tier municipality comments are included in the agency circulation on applicable applications.
Submit revised drawings and a response matrix addressing each agency comment. An inadequate response matrix produces further agency comments and extends the review cycle.
Required for all ZBA and OPA applications under the Ontario Planning Act. Notice period and radius prescribed by Planning Act regulations.
Council votes on the ZBA by-law amendment. Any party with standing may appeal the decision to the Ontario Land Tribunal (OLT) within 20 days.
Statutory minimums under the Ontario Planning Act. Actual timelines depend on application complexity, agency comment volume, and OLT appeal activity.
Studies are confirmed at the Pre-Application Consultation (PAC) stage and vary by site characteristics, proposed use, and triggering conditions specific to the property.

Look up my address →A zoning bylaw amendment in Toronto under Zoning By-law 569-2013 always requires a Planning Justification Report, Transportation Impact Study, and Functional Servicing and Stormwater Management Report. Additional studies are triggered by site characteristics confirmed at the Pre-Application Consultation (PAC) stage: Noise Impact Study (near rail, highways, or industrial), Natural Heritage Impact Study (near regulated natural features), Heritage Impact Assessment (near listed or designated properties), and others depending on the site. The Pre-Application Consultation (PAC) meeting produces the authoritative study list for 1st submission.
A standalone ZBA in Toronto requires a minimum of 90 days under the Ontario Planning Act before an applicant can escalate to the Ontario Land Tribunal (OLT). Most standalone ZBA applications take 14 to 24 months from 1st submission to Council approval. A concurrent Official Plan Amendment and ZBA requires a minimum of 120 days and typically takes 18 to 26 months to Council approval. Complex applications, multiple revision cycles, and OLT appeal activity can extend these timelines further.
A Toronto ZBA application is reviewed by the City Planning Department, Toronto and Region Conservation Authority (TRCA), and additional agencies triggered by the specific site. These include the upper-tier regional municipality for applications near regional infrastructure, provincial Ministries for certain land use changes, and utility agencies for development near utility corridors. The Pre-Application Consultation (PAC) meeting confirms the full agency circulation list for the specific site and proposed use.
A minor variance under Section 45 of the Ontario Planning Act is appropriate when the required relief is a minor, site-specific deviation from a numeric performance standard in Zoning By-law 569-2013 such as a setback, building height, lot coverage, or parking requirement without changing the permitted use. The Committee of Adjustment decides minor variances without City Council involvement. A ZBA is required when the proposed use is not permitted by the current zoning, when the deviation is significant, when multiple standards are being changed, or when an Official Plan Amendment is also required.
A ZBA changes the zoning of a specific property under Zoning By-law 569-2013 to permit a use or built form not currently allowed by the zoning. An OPA changes the land use designation in the Official Plan, which sets higher-level land use policies for an area. When a proposed development requires both a zoning change and an Official Plan policy change, both instruments must be amended concurrently, triggering the 120-day statutory clock. The Pre-Application Consultation (PAC) meeting confirms whether both are needed for the specific site.
Any party with standing can appeal a Toronto ZBA decision to the Ontario Land Tribunal (OLT) within 20 days of the Council decision. An OLT appeal suspends the Council decision and prevents the by-law from coming into force until the OLT resolves the appeal. OLT proceedings for a contested ZBA typically take 6 to 24 months, depending on the complexity of the issues and the hearing schedule. The developer, neighbouring property owners, and the City can all participate in OLT proceedings.
A returned ZBA application resets the 90-day statutory clock. A misidentified study scope means a 3-to-4-month delay at $43,000 per month in carrying costs. Enter your Toronto address and get your ZBA study list in 60 seconds.
