Sandbags come out as communities from Quebec to Manitoba prepare for spring flooding

St-Jérôme is among several municipalities across Quebec facing flooding. Environment Canada has said parts of southern Quebec had received up to 40 millimetres of rain since the start to the week, and forecasts are calling for more.

In Ontario, flood warnings are in effect across a large swath of the south by Lake Huron, stretching from Sault Ste. Marie to Peterborough.

The municipality of Central Manitoulin, located on an island in Lake Huron, was hit particularly hard by flooding. City officials declared a state of emergency and warned residents to use extreme caution when travelling, as multiple roads were closed. A water advisory has been put in place. Mindemoya Hospital, one of the island’s only hospitals, closed Wednesday after flooding impacted water and sewer services.

In Manitoba, officials are preparing for significant spring flooding in parts of the province, with emergency response efforts already underway. Flood preparations began last week after Peguis First Nation was warned that it could see water levels similar to those in 2022, when more than 2,000 residents were forced out, and hundreds of homes were damaged.

Dozens of volunteers from across the country have been in the community, located along the Fisher River north of Winnipeg, helping set up sandbags and build clay dikes to protect homes. Peguis First Nation Chief Stan Bird has said about 225 homes require flood protection, such as sandbags or water-filled barriers commonly known as Tiger Dams.

The community, considered the largest First Nation in Manitoba, has more than 10,000 members. Data from the federal government suggests roughly 3,800 live in the reserve.

In Quebec, Environment Canada spokesperson Frédérick Boulay said the province’s southern zone — from Gatineau to the Lanaudière region — is forecast to receive 10-15 mm of rain on Friday, followed by another 15-30 mm between Saturday and Sunday.

Émond said the Rivière du Nord has exceeded the height of the Viau bridge in recent years, “but we aren’t there yet,” noting that spring flooding has become more frequent and is “worrying.” Émond said no evacuations have been planned as of yet.

Boulay said a combination of snowmelt, rainfall, and ice breakup can all contribute to flooding risk, while a river’s shape and slope also play a role in whether waterways overflow.

Flood watches are in effect for several rivers across Quebec, including in the Lanaudière, Outaouais, Laurentians, and Quebec City regions, with minor flooding already reported in some areas.
