On August 20, 2009, a line of severe storms spawned a staggering 19 tornadoes in Ontario -- blowing away the province's entire annual average of twelve or thirteen per year.

More than 10 million people were living under a tornado watch or warning -- almost a third of Canada's entire population.

Among the twisters were a total of four that were rated F2, boasting winds up to 253 km/h.

Two were witnessed by thousands of people in the city of Vaughan in the Greater Toronto Area, where six hundred homes were damaged.

The other two F2s touched down in Grey County, one near Thornbury and another in Durham -- where an 11-year-old boy was killed, the outbreak's only fatality.States of emergency were declared in the worst-hit areas -- Grey County alone suffered around $30 million in damages.

It was the worst-ever tornado outbreak in Ontario's history -- and it came on the anniversary of the 1970 tornado that struck the province's Nickel Belt, killing six people.
