How to look up a building permit in Toronto
Toronto publishes its permit records itself, on a CKAN open-data endpoint at open.toronto.ca, in the dataset "Building Permits: Active + Cleared (since 2017)". That feed is the source this page reads, so a record here can be checked against the city's own copy. Search by civic address first, then confirm the permit number and the issue date. Records the city has not yet published will not appear in either place.
Van Permit Audit holds 565,241 Toronto permit records, current to 2026-09-24. See the full Toronto lookup guide for the step by step.
