Peel police and Mississauga fire were called to Torbam Road between Steeles Road and Derry Road before 5 a.m. for reports of drivers being stuck in the flood.
When paramedics arrived to the scene, one car was fully submerged with a man standing on roof of his car.
Heavy rains Saturday night through Sunday (Oct. 27) morning caused flooding in some areas of Mississauga including Torbram Road just south of Rena Road, where some motorists had to be rescued by emergency services due to rising waters.

Peel police say that the roads are expected to be clear in the next 6 to 12 hours. The water will need to be pumped out due to drainage issues at the site.
Firefighters in Peel Region rescued three people from vehicles that became 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.
Mississauga and Brampton firefighters moved the three people to safety and they were assessed by Peel paramedics.
Police are continuing to warn motorists about "extreme flooding" of Torbram Road. The area is north of Toronto's Pearson International Airport.
The rain began overnight and Environment Canada says between 25 mm to 40 mm of rain fell. The forecast calls for scattered showers on Sunday morning changing to drizzle by 12 noon.
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 and waterways have peaked due to the rain.
Water levels have receded or are now receding in its jurisdiction. Earlier, the authority issued a flood warning, but that has been rescinded.
"Due to the heavy rainfall from earlier today, some rivers within the GTA are experiencing higher flows and water levels, resulting in hazardous conditions. The combination of slippery and unstable banks could create dangerous conditions close to any river, stream or other water bodies," 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.
"Persons should stay well away from watercourses. We are continuing to monitor conditions," its statement reads.
