Firefighters in Peel Region rescued three people from vehicles that became partly submerged in floodwaters in Mississauga early Sunday.
The three were stranded in two vehicles — a work van and a car — under a rail bridge on Torbram Road, south of Rena Road. The area is between Steeles Avenue and Derry Road.
Peel police said emergency crews were called to the area shortly before 5 a.m.
Mississauga and Brampton firefighters moved the three people to safety and they were assessed by Peel paramedics.
Torrential rain poured over the area for much of the night
Early Sunday, police warned motorists about “extreme flooding” of Torbram Road. The area is north of Toronto’s Pearson International Airport. Police said they notified the City of Mississauga about the situation.
Motorists were urged to avoid the area.
As of Sunday afternoon, the road was still closed and Peel police said the flooding was partly due to construction in the area.
The flooding occurred when the Greater Toronto Area was under a special weather statement.
The rain began overnight and Environment Canada says between 25 mm to 40 mm of rain fell. The forecast called another 15 mm of rain on Sunday morning.
According to Environment Canada, heavy downpours can cause flash floods and water to pool on roads.
The Toronto and Region Conservation Authority, meanwhile, issued a watershed conditions statement for the GTA on Sunday, saying the GTA received between 20 and 45 mm of rain overnight Saturday into Sunday morning.
All shorelines, rivers and streams within the GTA should be considered hazardous, it said.
Earlier, the authority issued a flood warning, but that has been rescinded.
“Due to the additional expected rainfall, and the watercourses already responding to the previous rainfall, rivers within the GTA will be continuing to experience higher flows and water levels, resulting in hazardous conditions,” the statement reads.
Toronto residents are urged to exercise extreme caution around all bodies of water and to avoid driving on flooded roadways, underpasses and roads in low-lying areas.
The authority is also urging motorists to be alert to possible delays and road closures.
“Persons should stay well away from watercourses. We are continuing to monitor conditions,” its statement reads.
