Environment Canada Issues Weather Advisory for Heavy Rain Across GTA During CNE Weekend

TORONTO, ON — Environment Canada issued a special weather statement Friday evening for Toronto and the Greater Toronto Area, warning of localized heavy downpours and isolated thunderstorms capable of producing up to 50 millimeters of rainfall.

Meteorological Conditions and Urban Drainage

A slow-moving low-pressure system crossing the lower Great Lakes is expected to deliver sustained precipitation through Saturday afternoon. Toronto and Region Conservation Authority (TRCA) issued an urban watershed advisory, cautioning of elevated runoff in river valleys and low-lying transportation corridors.

"Urban drainage systems may experience localized pooling during intense thunderstorm cells," meteorologists advised. Motorists were urged to exercise caution on the Don Valley Parkway and Gardiner Expressway.

CNE Operational Adjustments

Canadian National Exhibition (CNE) officials confirmed that indoor exhibits, including the Enercare Centre and Food Building, remain fully operational with adjusted outdoor midway ride safety monitoring during peak rain periods.
