A woman has died after being pulled from the waters of Lake Ontario in Oakville.
Halton Regional Police said they responded to a call around 10:30 a.m. from someone who said several people were in distress in the water at Coronation Park.
The maritime unit attended and rescued a 10-year-old boy from the water. He was unharmed but was taken to the hospital as a precaution, police said.
Paramedics and firefighters also attended and helped pull a young woman from the water near the shore.
Police said Monday evening that despite life-saving efforts by first responders and the hospital, the young woman died.
The boy and the woman were not related, but were at the park together, police said. They said they would not release further details out of respect for the families.
Halton police did not say what the two were doing in the water when they ended up in distress.
Investigators from the Bureau of Criminal Investigation are investigating the fatal incident.
