St. Catharines declares emergency as back-to-back storms unleash historic floods

St. Catharines, Ontario, entered a state of emergency after a second deluge within a week overwhelmed the city’s drainage and sewer systems, leaving thousands of households underwater. Residents described water surging like a tsunami from the Niagara Escarpment, with some windows imploding and basements filling to the point of resembling Niagara Falls. Mayor Mat Siscoe, whose own home suffered repeated flooding, highlighted the emotional toll and the city’s inability to cope with nearly 400 mm of rain in a short span.

Fire chief Dave Upper reported dramatic rescues, including stranded cars on Ontario Street, and a surge in calls about short-circuiting electrical systems. High-rise tenants on Geneva Street were evacuated twice, receiving temporary shelter at the MacBain Community Centre with Red Cross assistance. Local officials are urging the Ontario and federal governments to supply emergency resources and consider long-term upgrades to storm-water infrastructure, while the Ministry of Municipal Affairs and Housing evaluates disaster-recovery assistance eligibility.
