10 years on, Ontario remembers destruction from historic 18 tornadoes in 1 day | CBC News
It was a decade ago that 18 tornadoes ripped through southern Ontario, marking the most tornadoes in a single day in Canadian history.
www.cbc.caHere’s a concise update on the latest reporting about the 1996 Southern Ontario tornadoes.
-
What happened: The Southern Ontario outbreak of April 20, 1996, included multiple F2–F3 tornadoes across Grey, Wellington, and surrounding counties, with particularly strong activity near Williamsford, Arthur, and nearby communities. There were no direct fatalities, and damage was extensive but concentrated in residential areas and infrastructure.[1]
-
Why it’s notable: It remains one of the most intense early-season tornado outbreaks in Canadian history, unusual for its date and its long, multi-tornado path through a populated region, followed by a rapid dissipation over Georgian Bay.[1]
-
Recent coverage: Contemporary articles and weather histories reiterate the rarity of such events this early in Canada’s tornado season, and note ongoing weather research contextualizing the outbreak within seasonal climate variability.[3][5]
