Development approvals in the Greater Toronto Area take far longer in practice than the Planning Act statutory clocks suggest. Site plan control has a 60-day statutory decision period but industry data shows GTA reviews averaging around 20 months, with residential nearer 16 months, mixed-use around 23 months, and non-residential up to 35 months. A zoning by-law amendment has a 90-day statutory clock (120 with an official plan amendment) but typically takes 12 to 24 months to council approval. Only minor variances resolve quickly, usually within 6 to 12 weeks.
The gap between what the Planning Act promises and what the GTA delivers is the central fact of Ontario development scheduling. The statute sets short decision clocks; the market runs on multiples of them. A developer who builds a pro forma on the statutory numbers is building on fiction. This page aggregates the realistic figures, by application type, so the schedule reflects reality.
The statutory period is the legislated decision window under the Planning Act. The typical actual is what industry benchmarking and provincial reporting show reviews really take across GTA municipalities. The difference is measured in months to years.
| Application type | Statutory clock | Typical actual (GTA) |
|---|---|---|
| Minor variance (Committee of Adjustment) | ~30-day notice | 6 to 12 weeks |
| Site plan control | 60 days | 12 to 24 months |
| Zoning by-law amendment (standalone) | 90 days | 12 to 24 months |
| ZBA + official plan amendment | 120 days | 18 to 30 months |
| Plan of subdivision | 120 days | 2 to 4 years |
Site plan control carries a 60-day statutory decision period once a complete application is accepted. Industry data tells a different story. Reporting on GTA and Ontario site plan review has shown average review times of roughly 20 months across all types, with residential projects nearer 16 months, mixed-use around 23 months, and non-residential developments as high as 35 months. Multiple review cycles, agency circulation, and completeness disputes account for most of the gap.
Timelines vary by municipality and by what your site triggers. PreBuildIQ estimates the approval path and study set for your specific address in 60 seconds.
Estimate my timeline →A standalone zoning by-law amendment has a 90-day statutory clock before an applicant can appeal a non-decision; a concurrent official plan amendment extends that to 120 days. Neither reflects the real timeline. A typical GTA rezoning runs 12 to 24 months from first submission to council approval, and longer where an official plan amendment, regional co-approval, or an Ontario Land Tribunal appeal is involved. The statutory clock is a floor for appeal rights, not a forecast of approval.
Several structural factors stretch GTA approvals well beyond the statutory clocks:
Carrying cost on a stalled GTA project runs about $43,000 per month. A single avoidable resubmission that adds three to four months is a six-figure loss, which is why getting the first submission complete is the highest-leverage decision in the schedule.
Minor variances are the exception. Decided by the Committee of Adjustment rather than council, they typically resolve within 6 to 12 weeks, sometimes on the day of the hearing after the statutory notice period. This is why correctly identifying whether a proposal can proceed as a minor variance rather than a rezoning can compress a timeline from years to weeks.
Site plan control has a 60-day statutory decision period under the Planning Act, but industry data shows GTA reviews averaging around 20 months. Residential projects average nearer 16 months, mixed-use around 23 months, and non-residential developments up to 35 months, driven by multiple review cycles and agency circulation.
A standalone zoning by-law amendment has a 90-day statutory clock (120 days with a concurrent official plan amendment), but a typical GTA rezoning takes 12 to 24 months from first submission to council approval. Applications involving regional co-approval or an Ontario Land Tribunal appeal take longer.
Approvals stretch beyond the statutory clocks because of multiple review cycles, completeness disputes that delay the start of the clock, parallel agency circulation to conservation authorities and regions, study revisions triggered by agency comments, and council and committee scheduling. Few applications are approved on the first submission.
The minor variance is the fastest. Decided by the Committee of Adjustment rather than council, it typically resolves within 6 to 12 weeks, sometimes on the hearing day after the statutory notice period. Correctly using a minor variance instead of a rezoning can compress a timeline from years to weeks.
The statutory timeline is the legislated decision period under the Planning Act, such as 60 days for site plan or 90 days for a rezoning, after which an applicant can appeal a non-decision. The actual timeline is how long approval really takes, typically many months to years longer, because of review cycles, agency circulation, and scheduling.
PreBuildIQ maps the approval bodies, required studies, and likely path for any Ontario address in 60 seconds, so your schedule reflects the real timeline, not the statutory fiction.
