Tornado and severe thunderstorm warnings for northwestern Ontario have ended, Environment Canada says.

The warnings changed rapidly throughout Monday evening as forecasts evolved. By 9 p.m. ET, all of the tornado warnings had been removed from the Environment Canada warnings website.

Severe thunderstorm warnings for surrounding areas were later dropped as well, though there was still a risk of storms in some areas.
