When does the Committee of Adjustment (CofA) apply to my Toronto project?

If your Toronto renovation misses any single as-of-right standard in the City-wide Zoning By-law 569-2013 — setbacks, floor-space index (FSI), height, lot coverage, parking, or permitted use — the project must obtain a minor variance from the Committee of Adjustment before Toronto Building will release a building permit. The CofA operates under section 45 of the Ontario Planning Act and reviews applications against the four-part test: variance is minor, desirable for the appropriate development of the land, maintains the general intent of the official plan, and maintains the general intent of the zoning by-law.

The end-to-end timeline runs 12 to 18 weeks. Pre-application consultation with the local district planner takes one to two weeks. Survey, drawings, arborist letter, and the application package take two to four weeks to assemble. Once filed, statutory notice goes to neighbours within 60 metres at least 10 days before the hearing, and circulation to Urban Forestry, Heritage, Transportation, and Toronto Water typically adds three to five weeks of comment time. The hearing itself is calendared four to six weeks out from filing, and the 20-day appeal window to the Ontario Land Tribunal runs from the decision date — only after that window closes can Toronto Building accept the building-permit application.

Common triggers we see weekly: rear additions that push FSI past 0.6 in R zones, third-storey additions on narrow Edwardian lots in Riverdale and Leslieville, side-yard tightening below the 0.9 m minimum, laneway suite setback exceptions under By-law 88-2019, and basement walk-out projects that exceed the soft-landscaping requirement. Cost is roughly CAD 600 to 1,800 in city fees plus survey, drawings, and optional planner letter. Build a 16-week buffer into your project schedule and assume one round of revisions before the hearing — a clean, four-test-aligned package wins the vote far more often than a marginal one.
