Every Ontario municipality has a sign bylaw. The authority comes from Section 99 of the Municipal Act, 2001, which lets municipalities regulate signs on both private and public property. But "regulate" is doing a lot of heavy lifting in that sentence, because what each municipality actually does with that authority varies enormously.
Toronto's Chapter 693 is a comprehensive document that runs to dozens of pages and covers everything from the maximum brightness of LED signs (measured in nits) to the minimum dwell time for electronic message centres. Petawawa's By-Law 1573/23 focuses heavily on portable signs because that is the issue that generated the most complaints in that community. Ottawa's By-law 2016-326 has bilingual signage provisions that no other Ontario city needs to worry about. Hamilton's By-law 10-197 had to reconcile six different pre-amalgamation sign bylaws into one framework.
The common thread is that all of these bylaws regulate the same basic things: what types of signs are permitted, where they can go, how big they can be, whether they need a permit, and what happens when someone breaks the rules. The specifics differ, but the structure is recognizable across the province.

When the MTO handles it and when your city does. Highway corridors, provincial roads, and the grey zones between jurisdictions.
Right-of-Way Signs
The right-of-way extends further than most people think. Why signs that look like they are on private property are actually on municipal land.
Signs on Public Property
Boulevards, utility poles, parks, bridges — where signs are prohibited outright and what municipalities can do about them without notice.
