Rigaud residents told to evacuate now, as flooding could be more severe than in 2017

The town of Rigaud, near the Quebec-Ontario border, is telling residents to pack up and leave their homes over the next 24 hours, as Thursday and Friday will bring heavy rains, and the resulting floods could be worse than in the spring of 2017.

Marie-Andre Gagnon, aspokesperson for the municipality on the Ottawa River, west of Montreal, said floodingwill crescendoover the next four days andwill worsen quickly once it starts.

"Almost all the houses that are near the water will be flooded or will have water [damage]," Gagnon said.

Environment Canada says 25 to 50 millimetres of rain is expected to fall in the region overThursday and Friday, and the still-frozen ground has a limited ability to absorb it. More rain is forecast for theweekend.

Pointe-Fortune also to be hard hit

When flooding hit the area in 2017, some 441 families were advised to leave their homes, but about 40 per cent decided to ignore the order.

The municipality of about 7,600and the neighbouring municipalityof Pointe-Fortunehave both launched emergency measures, although the evacuation advisory is notmandatory.

"If possible, go stay with friends or family. Buy food and supplies," Gagnon recommended.

Montreal, Laval issue warnings, too

Officials in Montreal and Laval are also bracing for flooding that could come by the weekend, as the storm clouds dumping rain near the Ontario border move further east.

StartingSunday, areas hit by flooding in 2017, including Pierrefonds,le Bizardand western Laval, could be in for more of the same.

In a worst-case scenario, some 800 residences in Laval could be impacted by rising water levels, according to Pierre Brochet, the director of Laval's police service.

Laval is being proactive by calling residents who are at risk of being flooded, he said, and it has committed to visiting them door to door Thursday.

Brochet said the city will also be delivering sandbags, and city workers will help residents place them if homeownersare not able to do so themselves.

"Sandbags we have in abundance. Don't worry," said Sandra Desmeules, the Laval executive committee member in charge of public security.

Desmeules said that the executive committee will be working through the weekend in anticipation of an emergency situation. She advised residents to go to the Laval website for updates as the situation develops.

Montreal has notgivenan estimate of how many residencesare at risk of flooding, but it said the same areas as 2017 will be affected.

Hydro-Qubec said Wednesday that many rivers, including the Outaouais, Gatineau, Mille-les and Saint-Maurice rivers "may experience drastic increases in water levels."

The public utility is advising residents to cut off power to their homes in case of flooding.

Pierrefonds-Roxboro, in Montreal's West Island, which was severely impacted in 2017, has installed water pumps on de la Rive-BoiseRoad and is closing it to traffic from Gouin Boulevard to David Street.
