It’s going to be a chilly night in parts of Ontario, with Environment Canada issuing the season’s first frost advisory.
Temperatures are expected to drop near freezing point overnight in southern Ontario as well as the northeastern region of the province.
The agency says residents should cover fruit trees and vegetable plants that may be damaged by frost.
The advisory extends from Cornwall in southern Ontario, west to Dufferin County, and north to Algonquin Provincial Park.
In the Greater Toronto Area, it covers the northern parts of the York and Durham area, including Newmarket, Georgina, Uxbridge and Beaverton.
Parts of Northeast Ontario, including the Greater Sudbury Area and North Bay, are also under warnings.
Environment Canada issues a frost advisory whenever temperatures are projected to reach 0 °C during the growing season.
