| Comments | Extensive flooding in April and May was experienced across Ontario, Quebec and New Brunswick due to a combination of heavy rainfalls and snow melt. In the Beauce region of Quebec, 154.5 mm of rain fell in April and was one of the first regions to be impacted by the spring floods.
The most severe flooding took place in Quebec where there were over 10,000 evacuees and over 6,600 flooded homes. One person was killed in Pontiac, QC, after the road washed out. In Sainte-Marthe-sur-le-Lac, a suburb of Montreal in the Deux-Montagnes MRC, a 15-23 m rupture in the natural dyke system forced the immediate evacuation of over 5,000 residents and 50 streets were flooded overnight on April 27-28th. Historical water levels were also experienced at the Chute-Bell hydro dam along Riviere Rouge where 50 residents of Grenville-sur-la-Rouge were evacuated due to fears of a dam failure.
States of emergency extended across the 3 provinces, including in Ottawa and Montreal. By the end of April, over a dozen states of emergency had been declared along the Ottawa River and its tributaries alone. Around 2,000 Canadian Forces personnel were deployed, which was more than the number deployed overseas. |
