A series of storms on the afternoon of August 19th 2005, spawned tornadoes damaging homes in the Conestoga Lake and Fergus areas, and a possible tornado within the Toronto city limits although this was never officially confirmed by Environment Canada. The storms developed near Stratford, Ontario (20 km west of Kitchener), and spread as far north as Georgian Bay near Collingwood, Ontario.

The main storm cell just to the north of Fergus, dubbed the "Toronto Supercell" spawned two F2 strength tornadoes that were particularly damaging, tearing apart trees, farms and overturning automobiles driving on a highway. The same storm cell later triggered a tornado warning in Toronto and caused extensive flooding in the Greater Toronto Area washing out many roads as well as damaging infrastructure such as storm sewers and electrical systems.
