Environment Canada has placed the Greater Montreal region under a snow squall watch, effective for Monday, January 19, 2026. The weather agency warns residents to prepare for potentially dangerous and rapidly changing conditions.
What a Snow Squall Watch Means for Montreal
A snow squall watch indicates that conditions are favourable for the development of intense, but localized, bands of heavy snow. These squalls can materialize with little warning, drastically reducing visibility to near zero in a matter of minutes and causing snow to accumulate quickly on roads. The primary threat is to motorists, as highways and streets can become treacherous and slippery almost instantly.
The alert covers the metropolitan areas of Montreal, Laval, and the surrounding South Shore and North Shore communities. This type of weather event is characterized by its sudden onset and is often associated with strong, gusty winds that lead to blowing snow.
Potential Impacts and Safety Precautions
Travel is expected to be particularly hazardous during squall activity. Environment Canada strongly advises that non-essential travel be postponed if a snow squall warning is issued. For those who must drive, officials recommend having a winter survival kit in your vehicle.
The sudden whiteout conditions pose a significant risk for multi-vehicle collisions on major roadways. The watch comes as other parts of the country also grapple with severe winter weather, including school bus cancellations and highway crashes reported in other provinces.
Residents should monitor updated forecasts and warnings closely, as a watch can be upgraded to a warning at any time. Preparing for power outages is also prudent, as heavy, wet snow and wind can bring down tree limbs and power lines.
Broader Context of Winter Across Canada
This alert for Montreal fits into a pattern of active winter weather across Canada. From the SnowDays festival in Banff to extreme cold events in the Prairies, the season is in full force. The timing of this squall watch also coincides with the return to work and school for many following the weekend, potentially amplifying its disruptive impact on commutes and daily routines.
Local authorities are likely to provide updates on any municipal services affected, such as public transit or waste collection. Citizens are encouraged to check official city channels for the latest information as the weather situation develops throughout the day.
