A rainfall warning issued by Environment Canada has ended for parts of Southern Ontario, including the City of Toronto.

The warning was first issued on Tuesday afternoon as a storm system carrying the rainy remnants of Patricia moved north from U.S. into southern Ontario.

The agency said a total of 44 millimetres of rain had fallen on Toronto by 2 p.m. on Wednesday, worrying officials about rising water levels in the Don River and other bodies of water.

Flooding caused by heavy rainfall also caused minor disruptions to service on GO Transit’s Richmond Hill line.

On Wednesday evening, the Toronto and Region Conservation Authority ended the flood warning for the GTA.

“The weather system that brought heavy rainfall to the Greater Toronto Area has passed. Showers will end this evening,” the TRCA said in a statement. “However, the weather forecast includes chance of showers for overnight and into tomorrow morning.”

The TRCA also advised that high water levels still pose a safety risk until the isolated flooding in the Toronto area dissipates.

The rainfall warning remains in effect for the following parts of Southern Ontario:

  • Pickering-Oshawa-Southern Durham Region
  • Niagara
  • Uxbridge-Beaverton-Northern Durham Region
  • Belleville-Quinte-Northumberland
  • Kingston-Prince Edward
  • Peterborough-Kawartha Lakes
  • Stirling-Tweed-South Frontenac

Environment Canada has issued a special weather statement for Southern Ontario heading into Thursday.

The agency warns that, despite the slowing rainfall, strong winds are expected to hit the province from east to west early Thursday morning.
