Ontario’s Weirdest Bylaws You Probably Didn’t Know

Ontario’s municipal bylaws aren’t all about parking and noise complaints—some of them are quietly hilarious. We dug through official town codes and reputable sources to find some of the strangest rules still on the books. Want to avoid awkward fines? Take note of these quirky laws!

🔇 1. No Whistling in Petrolia

In Petrolia, Ontario, it's illegal to “yell, shout, hoot, whistle, or sing” between 11 p.m. and 7 a.m. This odd noise restriction applies all day under the town’s noise bylaw—perfect for peace lovers, frustrating for spontaneous whistle-singers.

🚫 2. Swearing Ban in Rockwood Cars

Planning a road-trip with colourful commentary? Think twice in Rockwood. The town prohibits using profane language inside vehicles, and complaints from others could land you a fine .

🪜 3. Tree-Climbing Ban in Oshawa

Oshawa’s bylaws include a serious-sounding prohibition: no climbing trees on municipal property. That “tree house” you had in mind may not be tree-top legal—especially in public spaces .

🤐 4. Cursing Not Allowed in Toronto Parks

Toronto’s parks are peaceful—and profanity-free. The municipal code bans “profane or abusive language” in public parks, and violators can face fines over $200.

💰 5. Coin Limit on Payments

The federal Currency Act places practical—but odd—limits on coin payments: you can’t use more than 25 loonies or 5 quarters in a single transaction. Try paying a $30 bill entirely in toonies? Not legal.

🤯 Why These Rules Still Exist

These bylaws might seem eccentric, but they reflect local priorities—whether it's noise control, public decorum, or practical finance measures. Municipalities retain them unless officially repealed, and enforcement usually depends on public complaints.

ℹ️ Final Word

Next time you’re heading out:

• Avoid whistling at 2 a.m. in Petrolia

• Keep family rides PG in Rockwood

• Obey those “no climbing” signs in Oshawa parks

• And maybe leave the loonies at home
