A violent windstorm that struck a city in Quebec last Sunday evening has been determined to have been a tornado.

Environment Canada confirmed that the storm, which damaged more than 70 homes in Trois-Rivieres, was indeed a tornado, in a press conference on Monday, according to CBC.

No storm injuries were reported from Trois-Rivieres, which is located between Montreal and Quebec.

Environment Canada meteorologists rated the storm at F-0, lowest on the Fujita scale of tornado intensity.

According to the report, residents sighted rotating, fast-developing clouds. Moreover, the pattern of downed trees indicated tornadic winds.

Sunday’s storminess was far reaching in eastern North America, as a stormy cold front invaded both sides of the Canada-U.S. border.

Severe thunderstorms unleashing high winds, flooding rain and hail were observed in the eastern United States, and a tornado was caught on video as it touched down near Amsterdam, N.Y.
