Meanwhile, heavy rainfall overnight has created flooding on some roads around Toronto.
A special weather statement is now in effect for Toronto as "significant rainfall" continues into Wednsday. This is below Environment Canada's criterion for rainfall warning when the ground is frozen.
"More off-and-on rain is expected into early Wednesday until a cold front moves in and drops temperatures below freezing by Wednesday night, so things could get slippery".
"We do like to stress that people stay away from water courses because any low-lying area can have the potential for localized flooding", Rebecca Elliott, the TRCA's engineer of flood risk management, said.
