Environment Canada has issued a weather statement for Cornwall, Ontario, warning of a long period of freezing rain starting late tonight or early Wednesday morning, March 11, 2026. This storm is expected to bring between 10 and 20 mm of ice buildup, which could make travel hazardous and lead to significant disruptions in the community.
The icy conditions are forecast to last for up to 24 hours in some areas. Forecasters expect the freezing rain to continue through Wednesday and potentially into Wednesday night.
The heavy ice buildup will likely cause tree branches to break, which often leads to widespread power outages and utility problems. There is also a risk of flooding in low-lying areas if the rain falls too heavily to freeze immediately on the ground.
Residents in the Cornwall and Lancaster areas should prepare for difficult driving conditions and potential changes to their daily schedules. Local officials encourage everyone to keep an eye on weather updates as the storm moves through the region.
