The Windsor–Tecumseh Tornado of 1946 was the most powerful tornado to hit Windsor, Ontario, being an F4 in strength, touching down on June 17 of that year. 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.

The tornado took a northeastward path, cutting through farmland and forest, an area with few housing subdivisions (at the time, but still many homes), and narrowly missing Windsor Airport (which was located just south of the tornado), before tearing through the northwest part of the Town of Tecumseh, Ontario and dissipating over Lake St. Clair.

The storm's path was roughly 30 metres (100 ft) wide, and followed Turkey Creek for much of its length after crossing the Detroit River, and travelled 60 km. The storm's damage ranged from F3-F4, to some speculated F5 damage from completely destroyed houses that were lifted off their foundations.

Since the tornado had cut power to The Windsor Star's main printing offices downtown the Detroit News offered to help them print their newspapers at their printing facilities until the Star's were repaired, and even gave the Star priority so they could report the news of the tornado to the cities of Windsor, Detroit, and the rest of Ontario.
