After the remnants of tropical storm Debby brought historic rainfall and flooding to Quebec, the province continued to deal with the fallout Monday.

Provincial police confirmed the death of a man in his 80s who went missing late Friday after a roadway collapsed and he was swept into a river in the Mauricie region. His body was found Sunday.

Debby’s tail end, combined with a low-pressure system, washed out roads, flooded basements and knocked out power across southern Quebec.

Environment Canada said many communities along the St. Lawrence River received between 100 and 175 millimetres of water from the downpour.

“An event of this intensity is very rare,” the agency wrote on social media Monday.

Quebec Public Security Minister François Bonnardel said 55 municipalities were hit by flooding, with eight having declared a state of emergency.
