Freezing rain warnings remain in effect across southern Quebec. Some regions could see heavy rainfall later on Saturday as temperatures rise above the freezing mark and reach highs of up to 8 C.
Environment Canada warned the rain could result in flooding along some riverbanks that are already running high.
Radio-Canada reports that water levels along sections of Rivière des Prairies, Rivière des Mille îles and the South Shore of the St. Lawrence are under watch, as well as parts of the Richelieu Valley, Eastern Townships and Central Quebec.
Montreal-Trudeau, Highway 40 close
An early morning bout of freezing rain Saturday brought operations at Pierre Elliott Trudeau Airport briefly to a halt, forcing delays across the board.
Operations at the airport resumed around 10 a.m. but clearing up the backlog of delayed flights is expected to take a few hours.
Freezing rain was also to blame for a multi-car collision on Highway 40 near Portneuf that left one person injured and saw the road closed temporarily.
The collision involved eight vehicles in a chain-reaction set off by a car rear-ending a Sûreté du Québec cruiser that had pulled over to the side of the highway.
Roads conditions in southwestern Quebec had improved by noon but icy conditions will continue to affect roads in eastern Quebec into Saturday afternoon.
Stéphan Boivin, a spokesman for Transports Québec, said the temperature was making salt less effective on the roads.
“The salt is not working 100 percent. Later on in the day when the temperatures will increase the salt will work much better,” he said.
In Montreal, conditions are making it impossible to provide wheelchair adapted service on the city’s buses.
In Sherbrooke, buses are sticking to main roads only.
Quebec City's regional transit authority also warned passengers to expect delays.
Transports Québec is asking drivers to be cautious, and to delay their travel until later in the day, if possible.
