Environment Canada issued a yellow-level frost advisory covering parts of the Greater Toronto Area. The advisory applies to Toronto, Mississauga and Brampton, with the agency noting that freezing temperatures are expected Friday night into Saturday morning.

Potential Impacts
Environment Canada warned that the cold snap could damage plants, trees and crops. The advisory highlights the risk to ornamental horticulture and agricultural produce, particularly for vegetation that is not hardened against frost.
Official Guidance
The agency urged residents to take protective measures for vulnerable vegetation. Recommended actions include covering plants, moving potted items indoors, and avoiding pruning or fertilising until temperatures rise. Residents are also advised to monitor local forecasts for any updates.
Recommendations for Residents
- Cover or relocate sensitive plants before nightfall.
- Keep garden hoses drained to prevent freezing.
- Delay outdoor activities that could expose crops to the cold.
By following these steps, residents can mitigate the risk of frost-related damage during the brief cold period.
