Mississauga creeks and rivers flooding

All creeks and rivers in Mississauga are either at capacity or flooding into parks and greenspaces, the city said in a news release Saturday afternoon. 

People are advised to avoid all parks and trails surrounding Sixteen Mile Creek, Cooksville Creek, Credit River, Little Etobicoke Creek, Mimico Creek and Sawmill Creek.

City crews are responding to flooding on sidewalks, roads and trails, as well as dislodged maintenance hole covers and blocked catch basins, the release said. 

The 165th annual King's Plate, Canada's oldest horse race hosted by Woodbine Racetrack in Etobicoke, was also rescheduled. The race was set to begin Saturday, but heavy rains caused unsafe racing conditions, the racetrack said.
