Environment Canada has issued a frost warning for Brampton and the rest of the Greater Toronto Area.

According to the warning, an unseasonably cold arctic air mass is going to move into the area overnight. Temperatures will be dropping below zero degrees.

The frost is expected to move in overnight and stay well into Monday morning.

If you’ve already put out the potted plants and hanging flower baskets, it’s recommended they be brought indoors by Sunday evening to keep them protected.
