Environment Canada says southwestern Ontario is no longer under a tornado warning.
Meteorologists had been tracking a severe thunderstorm carrying strong winds, large hail and potentially intense rainfall.
The weather agency issued a tornado warning for the region shortly before 1:00 p.m.
One confirmed tornado was located north of Mitchell, Ont., but no damage has been reported.
Environment Canada urges people to take cover immediately if threatening weather approaches.
It says a roaring sound or funnel cloud would be a strong indicator of a serious storm approaching.
