The City of Montreal was hit by heavy flooding on 6 May, due to torrential rains and melting snow following the rise in temperature.  A state of emergency was announced and 1,900 homes have been flooded across 126 towns and cities in the east of Canada, across the province of Quebec. It has been confirmed by the local authorities that this safety measure will remain in place for about 48 hours.

Furthermore, this flooding not only affected the east of Montreal, but it also has its footprints on the west of Montreal. As a result, an emergency has been declared in the town of Rigaud and an order of evacuation has been issued by the mayor in the flood zones.

Besides Quebec, the province of Ontario has also been significantly affected by flooding caused by heavy rainfall. In southern Ontario, the Canadian Press news agency has confirmed that Lake Ontario's water level has reached an extent not seen since 1993.

MODIS true-color image of floods in Quebec from May 8, 2017.
Its been pretty overcast over much of eastern Canada the past several days - all of Quebec, and eastern Ontario, as in the above MODIS true-color image. Clouds have shifted slightly, but not dramatically over the past few days. Central Ontario is clear, but we dont see much there - there's a spot of "flooding" north of Toronto (by Barrie), but this is simply a wetland that is not in the MOD44W layer so shows up as flood.
