Three troughs moving through Ontario will bring on-and-off thunderstorm activity for areas stretching from Thunder Bay, down to Windsor, the GTA and eventually eastern Ontario and Quebec City. 

Storms will continue to impact northern, southwestern, southern and eastern Ontario through Monday, bringing isolated non-severe thunderstorms to the region.

"The main threat will be gusty winds and localized flooding, because the storms will be slow moving," said Weather Network meteorologist Brian Dillon. 

Environment Canada issued severe thunderstorm watches and warnings for many communities in northern and southern Ontario. Areas under warning included Orillia, Haliburton, Huntsville, Oshawa and Pickering, all of which dropped just before 10 p.m. EST.
