What are you building, and where?
Choose the municipality where the property is, not where the contractor works.
Selecting a city does not confirm permit requirements for a specific property. The next screen explains what is known and how to check further.

What BuildRules can and cannot confirm
1. The municipality
Identify the municipality without confusing places that share a name.
2. Sources and guides
See published guides or available official sources. A link alone never proves a permit is required or exempt.
3. The next action
Know what to ask and what to document before filing your application.
Some unorganized areas have no municipal permit office. If your address is not associated with a listed municipality, start with the provincial authority guide.
