Mississauga sits in the Great Lakes basin in Ontario, where a humid continental climate brings precipitation fairly evenly through the year, with the biggest flood risks coming from spring snowmelt and intense summer thunderstorms.
On Lake Ontario west of Toronto, the city’s Credit River can rise quickly during intense summer storms. Lake-effect weather patterns and the basin’s many rivers mean local flooding can develop quickly during a strong spring melt or a slow-moving summer storm, and Environment Canada’s radar network is a key tool for tracking both.
