Two Greater Toronto Area residents drowned in the region this weekend.

Fourteen-year-old Malcolm Gyamfi was swimming with a group of young people just after 4 p.m. Saturday at Hidden Acres Mennonite Camp near Stratford.

Some members of the group went beyond the roped-off area into deeper water and the teen disappeared under the surface.

Firefighters pulled him from the water.

Gyamfi was taken to Stratford General Hospital and then on to London's Victoria Hospital where he died about 11 p.m. Saturday.

Also Saturday, a 21-year-old Mississauga man died while swimming at a trailer park and resort in Port Colborne.

Niagara Regional Police say four visitors to the resort went swimming in an inland body of water around 9 p.m. 

Police say the man jumped into the water from a height of up to six metres, surfaced and was talking with his companions.

But a short time later, he slipped beneath the water and did not resurface.

His body was found at 12:40 a.m. Sunday.
