Certificate of Occupation (Business Permit)

Before leasing, buying or occupying a commercial or industrial space, or before operating a commercial business in your home, first make sure that municipal and zoning by-laws permit the intended use in the area.

You will need to obtain a certificate of occupation. This document tells you which uses or activities are permitted under the zoning by-laws in force on the date of issue.


Complete the Application for Business Permit (certificate of occupation) and attach the following documentation:

  • Copy of lease;
  • Power of attorney if the applicant is not the owner (mandatory).

If your business moves, undergoes a change of administration or closes, you must terminate your business licence (certificate of occupancy).

To do this, you must complete the Certificate of Occupancy Termination Request form.
