The Toronto and Region Conservation Authority has issued a shoreline hazard warning that applies to areas along Lake Ontario and the islands.
Lake Ontario’s water level is approaching 75.5 metres above sea level. During the flooding of Toronto Islands in April 2017, the water level reached a high of 75.93 metres.
“Properties along the shoreline and the Toronto Islands which experienced flooding during the 2017 event could begin to experience flood impacts as the water level in Lake Ontario continues to rise,” the warning said.
In addition to rain in the forecast, winds at 60 km/h are expected to bring offshore waves Wednesday.
The International Lake Ontario – St. Lawrence River Board is forecasting that lake water levels are expected to keep rising until late May or early June.
The flooding in 2017 resulted in Toronto’s islands closing for nearly three months along with all their local businesses and waterfront areas. The Island Public and Natural Science School also had to relocate to the mainland.
The flooding cost the city’s parks, forestry and recreation division at least $8.45 million.
