Environment Canada has issued a special weather statement for the Cornwall and Lancaster areas, warning of freezing rain and freezing drizzle expected to begin early Tuesday morning, March 31, 2026, and continue through early Wednesday morning, April 1.
The weather alert, which was issued late Sunday, is due to a Colorado Low pressure system moving through the region. This system is forecast to bring 20 to 40 millimetres of rain. Forecasters warn that temperatures near the freezing mark could create icy and slippery conditions on untreated roads, and residents should plan for potential power outages.
Motorists are advised to allow extra time for travel during this period. Drivers can check for the latest updates on highway conditions through Ontario 511. Previous winter weather events have led to hazardous driving conditions and temporary closures on Highway 401 between Belleville and Cornwall.
To prepare for potential electricity disruptions, utility companies recommend that residents have a 72-hour emergency kit on hand. This should include items such as flashlights, fresh batteries, water, non-perishable food, and necessary medication. For ongoing updates regarding power status, residents can consult the Hydro One storm centre.
Eastern Ontario has a history of significant ice events. Notable past occurrences include the January 1998 ice storm, which lasted more than 80 hours and resulted in widespread power outages across Ontario and Quebec, and a multi-day storm in March 2025 that affected over one million customers in Ontario.
