The City of Toronto has officially opened its beaches for supervised swimming this summer, with lifeguards stationed daily at ten locations until September 7. Mayor Olivia Chow announced a significant increase in staffing, with 4,080 employees hired, representing a 25% rise compared to previous years. Beaches open for swimming include Bluffer's Park Beach, Centre Island Beach, and Woodbine Beach, among others. Chow encouraged residents to heed the colored flag warnings: green indicates safe swimming, yellow suggests caution, red denotes danger, and no flag means there are no lifeguards present. Additionally, swimmers are urged to remain within designated swimming zones to avoid potential hazards from boats. Chow also reminded beachgoers to protect themselves from the sun and to plan their beach outings carefully. She emphasized the importance of swimming with children and never alone to ensure safety.
