The tornado that tore through Lachute, Que., on Tuesday left behind a trail destruction, and forced several dozen people from their homes.
But twisters aren't entirely unusual in the province. On average, 17 tornadoes hit Quebec and Ontario every year, according to Environment Canada. In the peak summer season — between June and August — an average of six hit Quebec alone.
But because most of them land far from populated areas, you rarely hear about them. Tuesday's twister in Lachute is a rare exception.
