On Saturday, the flooding claimed its first victim in the municipality of Pontiac, west of Ottawa.

MONTREAL: Flooding in eastern Canada forced the evacuation of more than 1,500 people while over 600 troops have been deployed in response, authorities said Sunday.

Warming weather over the Easter weekend has brought spring floods due to heavy rains and snowmelt from Ontario to southern Quebec and New Brunswick.

Authorities, who initially feared a repeat of catastrophic 2017 floods in Quebec, the worst in half a century, appeared more confident about the situation on Sunday.

"We are optimistic about the coming days," civil security spokesman Eric Houde told AFP.

"There will be significant floods but overall not at the level of 2017, except in certain areas like Lake St Pierre," a widening of the St Lawrence River in Quebec, he added.

"The big difference from 2017 is the level of preparation of municipalities and citizens."

Over the past several days, towns have mobilized volunteers and distributed hundreds of thousands of sandbags to erect barriers or protect houses in threatened areas.

The areas most affected were around Ottawa, and Beauce, a region south of Quebec City where nearly 800 people were evacuated. More than 1,200 homes had been affected by the flooding in Quebec by late Sunday.

The provincial governments of Quebec and New Brunswick asked for reinforcements from the military. 

About 200 soldiers had deployed in Quebec by late Saturday, and 400 others near Ottawa, in Laval north of Montreal and in Trois-Rivieres between Montreal and Quebec City.

About 120 additional soldiers stood at the ready to be mobilized in New Brunswick.

On Saturday, the flooding claimed its first victim in the municipality of Pontiac, west of Ottawa: a man in his seventies who did not see that a bridge had been washed away, and plunged his car into the stream below.
