The Toronto and Region Conservation Authority (TRCA) is warning that with the rain, along with melting snow and ice, water levels could be higher than normal. Slippery and unstable conditions along waterways could also pose a hazard.

“The big danger right now is the hazardous conditions right near rivers and stream, especially in Toronto’s parks, many of which are in river and stream valleys,” Ryan Ness of the TRCA explained. “The important thing for people to know is that the ice is not safe right now, it will not hold your weight. The water flowing underneath it is very cold.”
