The banks of the Don River were swollen with muddy, brown water but as traffic got onto GTA highways for Thursday morning's drive into work, the Don Valley Parkway was open.
Heavy rain caused flooding on the DVP Wednesday night. The freeways was shut down at 10:15pm south of Bloor Street.
It started to re-open around 6:00am.
The Toronto Region Conservation Authority is also asking everyone to stay away from rivers and lakes because they are at dangerously high levels.
That warning will continue throughout Thursday.
Some parts of the GTA received in excess of 50 millimetres of rain -- upwards of 2 inches and in central Toronto that could have hit as high as 3 inches.
The flooding was extensive. In variably the flood prone areas got hit the worst, meaning the lower end of the Don Valley Parkway, Pottery Road, the Bayview extension and Sunnybrook park.
On Wednesday, it wasn't long before reports of flooding were called into the NEWSTALK 1010 newsroom; specifically on off ramps from the 401 and up at Jane and Wilson, where a car was partially submerged and stuck.
"It's very hard to judge how deep that water is, and as we've seen in the past, people are tempted to negotiate those flooded areas only to be stuck, and eventually written off"
Constable Clint Stibbe went on to say they will be focusing on safety of people and drivers before helping get cars unstuck.
Toronto Fire officials were also called out to the Humber River Wednesday to come to the aid of people who somehow fell in.
"There was a male in the water who was able to get himself out, and a female was holding on to a tree, but we got a hold of her and brought her to shore," says Toronto Fire Captain Stephan Powell.
They were also called out to Sunnybrook Park near Leslie and Eglinton, to help rescue people out of vehicles that became submerged after a creek overflowed. Two people were rescued, but Toronto Fire officials say no one suffered injuries.
Both Toronto Fire and Police officials are reminding people to stay far away from the banks of the rivers, and if they are walking in the area with their pet and it gets caught in the water, don't go in and follow it. Often times animals will get out on their own safely.
