Burn ban in effect

With the dry weather, Ottawa Fire Services has issued an open-air fire ban for the city of Ottawa, including for persons and properties with an open-air fire permit.

This ban applies to agricultural burns, brush pile burns, campfires and wood burning outdoor fireplaces.

Propane, ethanol, and natural gas outdoor fireplaces and barbecues are not included in the ban.

OFS says the ban will remain in place until conditions improve and the green grass starts to show through tall dead grass.
