Environment Canada has issued an Orange Warning for a major freezing rain event in Cornwall, Ontario, on Wednesday, March 11, 2026. This severe weather alert means the community should prepare for a long period of icy conditions that could last up to 24 hours.
Forecasters expect ice to build up between 10 and 20 mm. This heavy ice is likely to cause power outages and damage to trees and buildings across the region.
Roads and sidewalks are expected to become extremely slippery, creating dangerous conditions for drivers and pedestrians. Local residents are advised to stay clear of any downed power lines and avoid travel unless it is absolutely necessary.
The Orange Warning is part of a colour-coded weather alert system used to show how much an event might disrupt daily life. While temperatures near the St. Lawrence River might rise above freezing later in the day, most areas should still expect heavy icing and potential service disruptions.
