A teenage boy has died in hospital after he was pulled from the waters off Woodbine Beach on Friday afternoon.
Toronto police say emergency crews were called to the area at about 2:30 p.m. Friday after a woman and her young son were seen distressed in the water.
Police say the boy and a woman jumped into the water to help them.
Emergency crews were able to rescue woman and her son, but the teen disappeared in the water.
Paramedics confirm they took three people to hospital, including the 16-year-old boy who later died, a 15-year-old girl in serious condition, and a third person in less serious condition. A fourth person was assessed at the scene and chose not to go to hospital.
