On June 30, 2025, a powerful storm created something unexpected near Lucan, Ontario—a tornado that touched down just north of the town. The Northern Tornadoes Project (NTP) from Western University, based in London, quickly responded on Canada Day to survey the damage. Researchers spent hours analyzing the storm’s path, helping us learn more about tornadoes in Ontario.
What Happened
That Monday afternoon, locals saw a funnel cloud swirling through the sky south of Lucan. It came down briefly and caused damage in nearby fields and woods . By the time NTP researchers arrived, they discovered a "very clear path" of destruction: flattened crops, snapped tree branches, and even parts of a barn scattered across the land.
One nearby farmer, Brenda Hawkins, pointed out where the tornado hit her property:
“It was the loudest sound I’ve ever heard,” she said.
“You can see there where it went through. Lots of tin from the old barns... I thought for sure the whole thing was going to be going.”
How Researchers Study Tornadoes
The NTP, led by David Sills and Aaron Jaffe, uses data from drone and satellite images combined with damage surveys to map tornado tracks. They go to the exact location, walk through the affected area, and mark how far the path stretched and how wide it was.
Jaffe shared:
“There’s some markings in the crops here where the tornado went through... You can see it really well from the drone. There’s trees here that had big branches snapped.”
By measuring damage types—like broken branches and structures—they estimate wind speeds. These estimates contribute to classifying the tornado using the Enhanced Fujita (EF) scale.
Why Timing Matters
The funnel cloud was spotted at 3:25 p.m., but the weather alert came out from Environment Canada at 3:49 p.m. . Though some residents asked why the warning came later, officials explained that small, fast-moving storms can be hard to predict.
Jaffe noted that while “in a perfect world” every twister would get advance warning, weaker or shorter tornadoes are especially tricky to forecast .
What This Teaches Us
Tornadoes Aren’t Just in the Prairies
Ontario’s tornado season is becoming longer and more active—a trend confirmed by NTP data.
Research Saves Lives
Mapping tornadoes helps scientists and officials improve warnings, track where storms occur, and advise communities.
Be Prepared
The Lucan storm reminds us Ontario residents should always heed weather alerts, stay informed, and have a safe shelter plan.
Learn with NTP
The Northern Tornadoes Project is a key research body, documenting severe storms, analyzing trends, and sharing results to make Canada safer.
What Happens Next
NTP will analyze all the data, estimate wind speeds, and finalize the tornado's EF rating.
Officials in Lucan and nearby towns will review the response and check warning timelines.
Families and farmers will clean up the fields and may reinforce barns and trees.
Environment Canada may adjust storm protocols to issue alerts faster next time.
