Much of Ontario and southwestern Quebec will stay very hot on Monday and Tuesday, as a heat dome continues to sit over the region.
Environment Canada gave a heat warning on Saturday and says the hot, humid weather will likely last until Wednesday.
In Toronto, temperatures reached 35°C on Sunday, but it felt more like 46°C with the humidity.
The extreme heat is expected to affect areas from southwestern Ontario all the way north to Sudbury and Timmins.
In Quebec, the hottest spots will be from Montreal to Shawinigan, and up north to Abitibi.
People are being told to drink lots of water to stay hydrated and watch for signs of heat exhaustion, like feeling dizzy or very tired.
