First of three Quebec tornadoes rated EF-0, significant damage produced

Wednesday, July 29th 2020, 8:52 pm - Severe thunderstorms hit Quebec on Monday, producing three tornadoes, one of which caused extensive damage.

On Monday, Quebec had the perfect formulation to cause severe weather, including three tornadoes. The storm was caused by the passage of a front, combined with extreme heat and oppressive humidity. Though the storm reached many areas across Quebec, three areas were hit by tornadoes.


The municipality of Saint-Mathias-de-Bonneterre, in Estrie, was hit by a tornado that caused significant damage to some homes and uprooted or snapped several large trees. A playground and baseball field were either partially or completely destroyed.

The tornado has been given a preliminary rating of EF-0 based on the damage observed, though it could change if new observations are obtained. Associated wind speeds were between 105-135 km/h.

A third tornado was confirmed near Armagh, in the municipality of Bellechasse. According to Environment Canada’s preliminary investigation, no damage was reported from this tornado and it has not been assigned a category.
