1946 Windsor–Tecumseh tornado
Tornado in Ontario, Canada
On June 17, 1946, a deadly and powerful tornado moved through the city of Windsor, Ontario, killing 17 people. The tornado was the most powerful tornado to strike Windsor, when it was at F4 intensity. The tornado touched down near River Rouge, Michigan, then crossed the Detroit River and made landfall in the Brighton Beach neighbourhood of Windsor. It then cut across southern Windsor and northern Sandwich West Township, Ontario (now the Municipality of LaSalle, Ontario), along a path 60 kilometres (40 mi) in length. It also cut across Highway 3 before weakening somewhat. The storm then touched down as an F4 again at the modern-day intersection of Walker Road and Grand Marais Road, near the center of the city.
