Severe Flooding in Pierrefonds and DDO: 20,000+ Without Power

Flooding Causes Widespread Power Outages and Road Closures

Severe flooding has struck the Montreal-area communities of Pierrefonds and Dollard-des-Ormeaux (DDO), leaving more than 20,000 residents without power and prompting police to close numerous roads. The flooding, which began on the afternoon of June 20, 2026, has overwhelmed local infrastructure as water levels surged rapidly following intense rainfall.

According to Hydro-Québec, over 20,000 customers lost electricity in the affected areas. Crews have been dispatched to restore power, but the utility warns that some outages may persist for an extended period due to the extent of the damage. Police have cordoned off several streets, advising motorists to avoid non-essential travel and to steer clear of flooded zones.

Emergency Response and Evacuations Underway

Local emergency services are on high alert, with rescue teams deployed to assist residents in the hardest-hit neighborhoods. In some areas, water has entered homes and businesses, prompting evacuations. The City of Montreal has opened temporary shelters for displaced residents, and officials are urging people to stay indoors and monitor official updates.

“We are facing an unprecedented situation,” said a spokesperson for the Montreal Fire Department. “Our teams are working around the clock to ensure the safety of all citizens. We ask everyone to remain calm and follow instructions from authorities.”

The flooding has also disrupted public transit, with several bus routes rerouted or suspended. The Société de transport de Montréal (STM) advises passengers to check for service updates before traveling.

Meteorological Context and Future Outlook

Environment Canada had issued a severe thunderstorm warning earlier in the day, forecasting torrential downpours and the risk of flash flooding. The storm system dumped over 100 millimeters of rain in some areas within a few hours, overwhelming drainage systems and causing rivers and streams to overflow their banks.

Meteorologists expect the rain to taper off overnight, but water levels may continue to rise in low-lying areas. Officials are monitoring the situation closely and warn that additional road closures may be necessary. Residents are encouraged to report any flooding or hazards to local authorities.
