The tornadoes that struck the Ottawa area on Friday, Sept. 21 damaged dozens of homes and left a trail of destruction, leaving communities picking up the pieces after home after home saw roofs torn off, vehicles tossed around, and huge trees and powerlines snapped.

The rural Ottawa neighbourhood of Dunrobin was one of the worst hit areas as the twin twisters tore through Ottawa and across the Ottawa River to Gatineau, Que.
