Will Kingston Schools Be Closed Tomorrow?
Kingston, Ontario sits at the northeastern end of Lake Ontario — a position that makes it one of Ontario’s premier lake-effect snow locations. Under northwest winds, cold air crossing the entire length of Lake Ontario from west to east accumulates moisture over the full fetch of the lake before depositing it as intense, heavy snow in the Kingston, Belleville, Napanee, and Prince Edward County area. Kingston is the core of what meteorologists call the “Lake Ontario snow belt.”

Kingston’s Lake Ontario Snow Belt Position
Kingston receives approximately 190–210 cm of snow per year — comparable to Barrie and significantly above Toronto. Under northwest winds (the most common winter direction), cold Arctic air picks up massive amounts of moisture over the full 300 km length of Lake Ontario and deposits it as intense snow in the Kingston area. A lake-effect event targeting Kingston can deliver 20–40 cm in 24 hours while Toronto, 250 km to the west on the same day, receives 2–5 cm from the same weather system.
Kingston Snow Day History
Limestone DSB averages approximately 5–8 closure days per year. The board covers significant rural territory in Prince Edward County, Leeds, and Grenville that has more exposure to drifting and blowing snow than Kingston city itself. Lake-effect events are the primary driver, most common in January and February.

Frequently Asked Questions — Kingston Snow Days
Why does Kingston get more snow than Toronto on some days?
Lake Ontario lake-effect snow. Kingston sits at the downwind end of the full 300 km lake fetch. Under northwest winds, moisture accumulates over the entire lake and deposits as heavy snow at Kingston. Toronto is upstream of this effect, not downstream. The same northwest wind that brings a few centimetres to Toronto can deliver 30+ cm to Kingston.
