Southern Ontario is facing its first blast of cold weather, reports CTV News Toronto. CTV says:
The federal agency extended its Sunday frost advisories across southern parts the province from York, Durham, Dufferin, and Halton regions, to cities like Ottawa, Kingston, Waterloo, and London.
According to the updated advisory, frost is expected Monday night again and right into Tuesday morning. It notes some plants might even get damaged or destroyed by the frost.
Residents are encouraged to cover their plants, and take precautions to protect their more frost-sensitive trees and plants.
