In the early morning hours of June 6, 2010, thunderstorms spawned three tornadoes in southwestern Ontario, along with significant downbursts.
The result was widespread damage in both Leamington and nearby Harrow. Metal was wrapped around poles, roofs were blown off houses and massive trees came crashing down on cars.
Thousands of residents were left without electricity and some were even left without a home.
"It was really scary and it was really hard because we had to move out for eight months," recalls Grade 5 student Luke in Leamington.
On the same night as the Leamington tornado, two other twisters -- rated F1 and F2 -- touched down in the Harrow area.
Ontarians are encouraged to prepare for severe weather, especially since the province usually sees around 12 tornadoes each year. Tornado season in Ontario usually begins in May and lasts through to September.
Meteorologists say it's important to have a general idea of the weather forecast at all times to know when the uglier conditions could arrive.
"There are very few days in a year when there is any real chance of danger, and our job is to make sure you’re aware of those days with tornado potential. Let’s make sure we’re ready," warns Chris Scott, a meteorologist at The Weather Network.
