The hurricane affected mostly the western and southern regions of Ottawa and Gatineau, a city located across the river from the Canadian capital in the province of Quebec.
"It's in the top two or three traumatic events that have affected our city," Ottawa Mayor Jim Watson told reporters. "It looks like something from a movie scene or a war scene."
One of the citizens, Joshua McEvoy, who lives in the Centretown West part of Ottawa, almost had his wedding ruined because of tornado.
McEvoy was in the process of getting married on Saturday, but his big day took an unfortunate turn when he learned that his uncle, Leo Muldoon, had been injured in the tornado while trying to repair a barn.
Moreover, the restaurant the couple had chosen for the event six months in advance was struck by a power outage.
The brave lovebirds decided not to change their plans.
The exact extent of the destruction remains unknown, but at least three buildings have been completely destroyed, and a few dozen have lost their roofs.
Numerous private and multi-story houses were left without light.
