Sign bylaws in Ontario are municipal. The rules in Toronto are not the rules in Ottawa, which are not the rules in Petawawa. Each municipality has its own bylaw with its own definitions, size limits, permit requirements, and enforcement approach. Knowing the general principles of sign regulation is useful, but to actually comply — or to report a violation effectively — you need to know your city's specific bylaw.
These guides cover the major Ontario municipalities and a few notable smaller ones. Each guide identifies the specific bylaw, key provisions, enforcement contacts, and the issues that make that city's approach distinctive.
