Days of rainy weather in southern Quebec and eastern Ontario have taken a toll on the region and Canadian soldiers have been asked to help.
High water levels have threatened hundreds of homes and at least 700 residents have been evacuated.
Ile-Bizard, west of Montreal, has been especially hard hit with sand bags helping to keep back rising water in some areas.
In New Brunswick, a low pressure system could bring 50-100 mm of rain to western areas of the province where rivers are already full of water this weekend.
More than 100 vehicles were involved in a pileup on Ontario’s Highway 401 outside the Greater Toronto Area last weekend.

A Colorado Low brought an early taste of winter to a large swath of Central Canada.
Most of the region saw its first measurable snow of the season with the highest amounts in eastern Ontario (Ottawa 16 cm, Kingston 18 cm) and western Quebec (Mont-Tremblant 15 cm, Montreal 5 cm).
Strong winds were also a factor gusting up to 70 km/h in the Greater Toronto Area and even up to 90 km/h in some areas.

With a Colorado Low heading to New Brunswick tomorrow bringing a mixed bag of precipitation, travel could be tricky as the Easter long weekend begins.
Environment Canada has issued snowfall and freezing rain warnings for most of the province except the south from an area including Greater Moncton to Saint John and St. Stephen.
The storm originated over the American Rockies in Colorado where more than 30 cm of snow fell before it swept across the Great Plains along with Ontario and Quebec.
NB Power says it is ready for the storm with staff on standby and 60 contractor crews spread over key areas of the province in the event of outages.

The coldest shot of winter 2015-16 has enveloped New Brunswick with an early morning low of -21.0 C in Greater Moncton and as frigid as -32 C in central and northern parts of the province.
Wind chills could drop as low as -35 by Monday morning.
The Arctic dome of air has also led Environment Canada to issue extreme cold warnings for much of Ontario, Quebec, Labrador and all of New Brunswick except the Southeast and Fundy coast.
Extreme cold warnings are issued when very cold temperatures or wind chill creates health risks such as frost bite and hypothermia.
