The thunderstorm threat will sink south throughout the day, but the better chance for more severe storms in southern Ontario will be on Canada Day Tuesday.
Much of the province can expect daytime highs near 30°C on Monday, feeling closer to 40 with the humidex.
2. Potent Canada Day storms expected in Ontario
All eyes are now focused on a cold front that's set to make its way into the region on Canada Day.
"The impeding cold front will trigger severe weather for southern Ontario and southern Quebec Tuesday," says Weather Network meteorologist Brian Dillon. "These thunderstorms have the potential to produce torrential downpours and gusty winds."

3. Prairies face flood emergency
A large and intense low pressure system has brought between 100-200 mm of rain across parts of the Prairies since Friday morning.
That has resulted in numerous evacuations and local states of emergencies across Saskatchewan and Manitoba.

Regina's fire department tweeted Sunday night that the sewage system was working at full capacity, and that residents should delay showers, baths, and even flushing toilets to prevent additional strain on the system.
"Rain continues over the hardest hit areas with another 15 mm or so expected today," said Environment Canada in a rainfall warning issued early Monday. "The rain should taper off later this afternoon with only slight accumulations into the overnight period."
Residents are being urged to watch for possible washouts near rivers, creeks and culverts.
