On Sunday, March 22, 2026, a Environment Canada special weather statement remained in effect for Mississippi Mills, Ontario, as snow and freezing rain moved through the region. The statement for Eastern Lanark County predicted between 5 and 10 centimetres of snow, which caused slippery conditions on local roads and walkways.
The heaviest snowfall occurred on Sunday morning, with rates reaching up to 3 centimetres per hour. Forecasters warned that a mix of freezing rain and freezing drizzle could make travel difficult for residents throughout the day, prompting officials to advise extra travel time for those on the move.
The Municipality of Mississippi Mills is responsible for plowing, sanding, and salting more than 360 kilometres of roadway during winter weather events. This latest storm follows an active month that included a significant freezing rain event on March 11, 2026, which required the closure of several municipal facilities.
Earlier in the month, the Mississippi Valley Conservation Authority reported that the local snowpack was at 150 per cent of its normal levels. Officials continue to monitor these conditions as the combination of high snow levels and new precipitation can increase the risk of spring flooding in the watershed.
By Monday, March 23, 2026, weather alerts were lifted and conditions in Almonte improved to mainly sunny skies. Temperatures returned to approximately -5C as the weather system moved out of the Eastern Ontario region.
