Heavy rain and thunderstorms drench large stretch of Ontario, bringing flooding risk
Written by The Canadian Press on April 14, 2026
A round of heavy spring showers and thunderstorms is set to drench a large stretch of Ontario today, with possible flooding in some areas.
Environment Canada has issued a series of weather statements and warnings spanning Sault Ste Marie and Sudbury to the north, east to the Ottawa region and beyond, most of the Greater Toronto Area and southwest to Sarnia and Windsor.
The weather agency says some areas could see as much as 30 millimetres of rain today through Wednesday.
It says the ground is already near saturation, with little ability to absorb more rainfall, and water will likely pool on roads and in low-lying areas.
The agency is urging people not to drive through flooded roadways and to watch for washouts in areas near rivers, creeks and other waterways.
It says to consult local conservation authorities and Ministry of Natural Resources offices for flooding information.
