The f-word has reared its chilly head for the first time this season.
Environment Canada has issued a frost advisory for the region, with an overnight low of just +2 Celsius.
Frost advisories are issued when temperatures are expected to reach the freezing mark during the growing season, leading to potential damage and destruction to plants and crops.
Officials say fruit trees and vegetable plants may be damaged by the cold temperature, and residents are urged to cover up frost-sensitive plants.
