Toronto / Practical guide

What if work started before the required permit was issued?

Contact Toronto Building and establish the permit path before continuing work that requires a permit.

City of Toronto source reviewed 2026-09-30.

The City says work must stop while the required application is processed. Additional administrative fees, remedial work and delays can follow. Hiring a contractor does not remove the homeowner’s responsibility.

Record the scope and work already completed. Discuss the next steps with the City and the appropriate design professional. Do not treat an application submission as approval to continue.

Your next steps

  1. Document completed and planned work.
  2. Confirm the permit requirement with Toronto Building.
  3. Discuss drawings and any remedial work with your designer.
  4. Wait for the required approval before continuing.
