Jason Thistlethwaite, professor in the School of Environment, Enterprise and Development at the University of Waterloo, said Quebecers can expect flooding to get worse because climate change is making winter temperatures more volatile.
MONTREAL — Quebec’s history, mythology and culture are intertwined with its rivers and lakes, but recurring floods that experts say will only get worse because of climate change are forcing Quebecers and their political leaders to rethink their relationship with water.
In 17th century New France, land was distributed to settlers in long, rectangular strips with access to the river. More than 300 years later, Quebec entered its modern era in large part through the development of its massive hydro-electric potential.
Alexandrine Bisaillon, a researcher with the climate change think tank Ouranos, said the province was founded on the belief that water can be controlled. But as increasingly frequent spring floods force evacuations and damage property, Quebecers are being forced to adapt.
“It’s a question of whether we want to be masters of water or live with water,” she said.
Rivers across the province are being monitored closely and authorities say they fear water levels over the weekend could rise as high as they did in the spring of 2017, when thousands of homes were flooded around the Montreal area.

Sudden waves of warm weather followed by quick drops in temperatures increase the risk of ice accumulating on the rivers in the winter, he said. The ice jams act as a dam, holding back water, and when the ice begins to melt and move, the dam bursts.
That’s exactly what happened in Beauceville this week, when an ice jam broke and water rushed through downtown, flooding at least 230 buildings in the small town south of Quebec City.
Across Quebec, prime locations are often by a river or lake. Restaurants and tourist areas boast of a view of the water. But Thistlethwaite said Quebec might want to adopt a practice known as “making room for the river.”
Instead of looking at the shoreline as high-priced property on which to build, Quebecers should consider returning these areas to nature and turning them into parks, summer sporting facilities or public land, he said.
The provincial government’s new compensation program for flood victims is in line with this approach, Thistlethwaite said. The new rules announced on April 15 limit total compensation for victims of recurring floods to 50 per cent of a home’s value, or a maximum of $100,000.
Once damage exceeds that amount, people can no longer claim compensation for that home, but they can receive up to $200,000 to relocate to an area outside the flood zone.
The new rules, Thistlethwaite said, are “very progressive of the government of Quebec, and they should be emulated across Canada.”
In Beauceville earlier this week, a displaced resident told The Canadian Press she was ready to move. Sylvie Dufour’s car was washed into her yard and her basement was filled with several feet of ice and water, right up to the main floor.
She welcomed a compensation plan that would allow her to move once and for all. “If I get $70,000 to relocate tomorrow morning, I’m the first to raise my hand,” Dufour said.
Bisaillon said Quebecers have some tough choices over the coming years. “Water is a collective good,” she said. “But we also privatized access to it. Can we take this opportunity to give back access to the water to the public?”
