A Toronto man has died in a suspected drowning on Six Mile Lake.

According to County of Simcoe Paramedic Services, the body of a 23-year-old man was found under a bridge on Sunday, at around 6:30 p.m.

Emergency crews attempted to revive the man, but he was later pronounced dead at the scene. Paramedics say the man was swimming with a friend when they were separated.

Officials say the circumstances are still unknown, as they wait for the results of an autopsy.

Kaitlin Osborne is a trained lifeguard, who's been coming to the area for years. She says it's definitely not as safe as it might seem.

"There's a lot of undertow on the other side. If the dams open you're definitely going to get swept away."

The unstable nature of the water in the area is precisely why the District of Muskoka has installed these barriers on the bridge over the dam to prevent people from jumping.

“We believe that the installation of the new guard railings and hazard warning signs are an important step to improving safety. We are doing everything possible to advise people that it is unsafe to jump from the bridge and having a barrier to restrict access,” the district said in a statement.

Police are also asking people to be cautious and recommend not swimming in areas they’re not familiar with.
