Almost 1,900 homes in 126 Quebec municipalities have been flooded, with more than 1,000 residents leaving the affected areas, the Canadian Press reported, adding that some 1,200 troops were deployed to help evacuate local residents.
"It's a serious situation, but people should know that every level of government is pulling together seamlessly to do everything necessary to keep Canadians safe", Ralph Goodale, public safety minister, told reporters in Ottawa.

More than 2,000 homes have been flooded in 130 towns and cities, with authorities urging residents to evacuate before it is too late.
The Canadian military will deploy about 1,200 troops to help deal with the flooding, local media reported.
Their tasks included evacuating residents, reinforcing dikes and protecting critical infrastructure such as water treatment plants and bridges, the ministry of defense said.
