Two men were seriously injured and thousands remained without power as a result of Monday night’s windstorm, when gusts reached 100 km/h.
A barn under construction in the southern Ontario township of Adjala-Tosorontio Township collapsed just before 6 p.m., trapping two men, aged 63 and 25, who were taken to hospital.
Meanwhile, crews across Ontario and Quebec continued working Tuesday to get the power back online.
By late afternoon, some 30,000 Ontario customers and more than 5,000 Quebec customers were still in the dark.
"This violent wind storm has caused widespread damage," Greg Towns of Ontario’s Hydro One said in a statement.

"More than 1,200 employees from our lines and forestry crews are out in full force and we appreciate our customers’ patience."
Hydro One said it also deployed five helicopters to assess damage and move equipment.
Hydro-Quebec said, via a tweet, that it had more than 240 crews "hard at work, and we will continue our efforts to restore service as quickly as possible."
Giant trees snapped like toothpicks under Monday night’s windy blasts, bringing down power lines and hydro poles.
Winds in were expected to die down to 5 km/h throughout this week, according to The Weather Network.
Social media lit up with wind warning and damage reports Monday night, including the odd humorous observation.
"Something tells me the neighbour’s tree isn’t supposed to look like that," one Londoner tweeted, with a picture of a fallen evergreen.
