The remnants of tropical storm Debby made landfall in eastern Canada, where parts of Quebec and Ontario were already drenched by heavy rain early Friday.
Environment Canada issued a swath of warnings for the two provinces with upwards of 100 millimetres of rain expected in some areas.
A low pressure system is passing through Southern Ontario and Quebec with alerts in effect from Cornwall, Ont., through to Quebec City about the risk of flash flooding. Minor landslides are also a possibility in some areas, according to the weather agency.
Environment Canada said “significant amounts” of rain had already fallen by 6:30 a.m. in southern Quebec and its forecasts have been “revised upwards.” By that time, Montreal had already received 31 millimetres of rain — with that potentially rising to as much as 120 millimetres by the end of the day.

In Montreal, flooding hit some roads during the morning commute. Quebec’s Transport Ministry warned parts of major streets and off-ramps were off limits to drivers in the city, including Highway 19 between Henri-Bourassa and Gouin boulevards.
“Heavy rain! Adapt your driving to reduce the risk of hydroplaning,” the ministry wrote on social media.
In Ontario, Debby’s last gasps could dump as much as 100 millimetres of rain on Ottawa and Kingston. The downpour should taper off by the evening, the agency said.
The wet weather is expected to reach New Brunswick Friday night and bring up to 40 millimetres of rain through Saturday morning.
