Major Ice Storm Set to Impact Eastern Ontario and the Ottawa Valley This Week: What GTA Residents Should Know
Ontario is preparing for a significant and potentially critical ice storm starting Tuesday evening, as a moisture-laden system from the southern U.S. brings a complex mix of snow, ice pellets, and freezing rain to the province. According to The Weather Network and Environment Canada, prolonged freezing rain could last up to 24 hours in parts of eastern Ontario, posing a serious risk of tree damage, broken branches, and extended power outages .
While southern Ontario, including the 401 corridor, is forecast to see mainly heavy rain and even thunderstorms, communities east of Georgian Bay toward the Ottawa Valley are facing the highest risk of significant ice accretion . With the potential for 10 to 30 mm of freezing rain, property managers, contractors, and businesses in the affected regions should prepare for hazardous conditions and a potential surge in demand for bulk salt and de-icing materials .
What The Forecast Says
A powerful low-pressure system will move into Ontario Tuesday evening, initiating a 24-hour weather event that will persist into Thursday morning. The storm will arrive in waves, with an initial round of snow, ice pellets, and freezing rain lasting through Wednesday morning. After a possible lull, a second, more intense wave is expected Wednesday evening .
The Weather Network and Environment Canada report the following:
Freezing Rain: 10-30 mm of freezing rain is likely in far eastern Ontario, including the Ottawa Valley. Some areas could see ice accumulation for up to 24 hours . Environment Canada has warned that this could be a "significant" and "potentially critical" event .
Snowfall: Communities southeast of Lake Superior, including Timmins and Sudbury, are forecast to see heavy snow with totals of 10-20+ cm .
Rainfall: Southern Ontario, including the GTA, will see periods of heavy rain and embedded thunderstorms Wednesday morning, with totals reaching 20-40+ mm .
Impacts: Significant ice buildup is expected on trees and utility infrastructure, increasing the risk of tree damage, broken branches, and widespread, prolonged power outages. The combination of heavy rain over frozen ground also raises the potential for localized flooding in low-lying areas .
Travel: Drivers should expect slippery, untreated roads. Those travelling through Ottawa should prepare for potential flight delays or cancellations, as icy conditions at major airports like Ottawa and Montreal are likely to disrupt travel .
Rising Demand for Bulk Salt and Winter Materials
While the GTA is expected to escape the worst of the freezing rain, the shift to colder air behind the system will bring a sharp drop in temperatures by Thursday. Colder air moving south across cottage country and southern Ontario will cause any standing water or wet surfaces to freeze, creating slick roads, sidewalks, and parking lots . A clipper system is also forecast to move through the region on Friday, bringing 5-15 cm of wet snow over the recently fallen ice and precipitation .
Whenever mixed precipitation and rapid temperature drops threaten the province, demand for bulk salt and ice melt increases sharply. Contractors and property managers will need to act quickly to treat surfaces before they freeze. Searches for local rock salt distributors and winter maintenance supplies typically surge during events like this as teams prepare to respond to fast-changing conditions.
As one of the most established salt distributors in southern Ontario, Draglam Salt is prepared for increased demand across all GTA locations, including Vaughan, Concord, Scarborough, Mississauga, Niagara Region, Ottawa, Windsor, Toronto, Etobicoke, Oakville, Hamilton, Bradford and Brampton. With a strong inventory, reliable access to bulk road salt, and multiple pickup sites, Draglam Salt continues to provide dependable service when winter weather intensifies.
Why Preparation Matters This Week
Ice storms are particularly dangerous because ice accretion is not always immediate. Factors like wind, precipitation intensity, and surface temperature can influence how much ice actually builds up . However, when temperatures plummet behind the storm, any moisture on pavements will freeze instantly. For this reason:
Contractors should stock up early on bulk salt to avoid delays as the cold air moves in.
Property managers need to monitor hourly weather updates to time applications for stairs, walkways, and lots.
Businesses should ensure they have a reliable salt supplier nearby to handle post-storm treatment.
With additional wintry weather possible this weekend and into next week, advance readiness is more important than ever.
