Outdoor fire rules and permits
The rules you need to follow to have an outdoor fire in Ontario and how to get a fire permit.
Check with your local municipality before completing any open burning. Depending on your municipality, you may need to follow more rules or get a permit.
The law
If you live in Northwestern, Northeastern or North-Central Ontario, you must follow certain rules to have an outdoor fire.
Figure 1 – Legislated fire region of Ontario
By law, you need a fire permit to burn wood, brush, leaves and grass outside during the fire season (April 1 to October 31) unless you follow all the rules:
- you’ve checked the by-laws of your local municipality and, where required, got a permit from your municipality
- conditions allow the fire to burn safely until extinguished
- you take all necessary steps to tend, control and extinguish the fire
- you are not starting an open fire in a restricted fire zone
If you burn material without a permit when one is needed or do not practice safe burning, you can be fined and held responsible for the cost of putting out the fire and for any property damage.
