Environment Canada has issued a frost warning for areas north of the Greater Toronto Area, Friday.
The warning is in effect for:
- Bancroft – Bon Echo Park
- Parry Sound
A chilly Arctic air mass moved in Friday, bringing with it brisk northerly winds making it feel much more like October.
The weather agency said frost will likely develop overnight and into early Saturday morning.
Tender plants should be protected or brought indoors away from the cold Friday evening if possible.
