A late-season, record-setting heat wave prompted Ottawa Fire Services on Sunday to ban all open air fires in the city, even for permit holders.
The measure is precautionary to avoid possible grass or bush fires due to hot, dry conditions across the region.
It also applies to residents or landowners who have a municipal Open Air Fire Permit intended for campfires, brush pile and agricultural burns.
