PROVINCE OVERVIEW
Ontario home permit guides
Ontario municipalities issue building permits within the provincial building-code framework, but zoning, conservation, heritage and trade approvals can still be separate.

Why the city page still matters
Province-wide code context does not replace zoning, local submission rules, heritage/conservation controls, trade permits or property-specific requirements. Use the official municipal link on the city page before starting work.
