Heavy flooding forced commuters to reroute their path downtown Sunday night.
Flooding was reported on the Don Valley Parkway, the Bayview extension as well as parts of Lake Shore Blvd.
The rainy weather hit southern Ontario Sunday night after environment Canada warned of thunderstorms and even a potential tornado in some part of the province.
By 4:30 p.m. forecasters said the tornado threat was over for the areas of Windsor, Essex County, Leamington, Chatham-Kent, Sarnia and Lambton and other regions.
A special weather statement was posted on the national weather agency's website warning residents of heavy rain for the rest of southern Ontario.
"There is a slight risk that some of these storms may be severe with damaging winds, torrential downpours…and large hail being the main threats," the statement says.
The severe thunderstorm threat will continue overnight.
