Residents in Barrie, Ontario, are facing a risk of localized flooding today as a heavy rain system moves through the region. Environment Canada issued a yellow rainfall warning on March 11, 2026, for the area including Barrie, Collingwood, and Hillsdale.
Forecasters expect between 20 to 40 mm of rain to fall throughout the day. Some areas could see even higher amounts if thunderstorms develop during the storm.
The rain is a concern because the ground in the region is currently frozen or soaked from previous weather. This means the soil cannot absorb the water, which leads to pooling on roads and flooding in low-lying spots.
Authorities advise residents not to drive through any flooded roads they encounter. It is also important to watch for washouts near local rivers, creeks, and culverts where the water may rise quickly.
The Ontario Ministry of Natural Resources also provides information regarding the ongoing flood risks in the province.
