1970: Freak tornado kills six in Sudbury

The Story


"My house is blowing away, my house is blowing away," a hysterical female voice over the phone shouted, then the line went dead. That call to a Sudbury radio station was the first hint that a summer thundershower had turned deadly. On Aug. 20, 1970, a 100-mile-an-hour tornado ripped through the northern Ontario mining town of Sudbury and the surrounding communities of Copper Cliff, Lively and Field without any warning. The 10-minute windstorm resulted in the death of six people, injured 200 and caused over $17 million in damage. It was one of the worst tornados in Canadian history.

• The 1970 Sudbury twister was considered unusual because tornados generally don't occur so far north in Canada.

• According to Environment Canada, about 80 tornadoes cause a yearly average of two deaths and 20 injuries in Canada. The odds of dying from a tornado are one in 12 million.

• Dr. T. Fujita, a pioneer in tornado research, is responsible for the Fujita scale. The scale measures the intensity of tornados with F0 being the least intense and F5 being the most intense.
