Zoning By-law

Toronto is governed by City-wide Zoning By-law 569-2013. The zoning by-law determines what you can build on your property, including permitted uses, building height, lot coverage, setbacks from property lines, and parking requirements.

A PermitSnapshot report analyzes your specific property against the applicable zoning by-law and identifies any potential issues or variance requirements before you apply for a building permit.

Conservation Authority

Toronto is within the jurisdiction of the Toronto and Region Conservation Authority (TRCA).

If your property is near a waterway, wetland, shoreline, or flood-prone area, you may need a permit from the conservation authority under Ontario Regulation 97/04 before construction can begin. PermitSnapshot checks conservation authority mapping for every report.
