A Mississauga man is dead after he and his daughter were pulled from the water near Guelph on Saturday evening.

Ontario Provincial Police said they were called to a conservation area in Rockwood just before 6:30 p.m. for a drowning.

A 33-year-old man and his seven-year-old daughter were in an inflatable boat when it capsized, police say.

OPP Const. Joshua Cunningham said bystanders "went into rescue mode" and pulled the man and the child from the water.

"We don't exactly know who was all involved with even the rescue, so we're actually imploring to the people who were there and haven't spoken to police to contact us," he told CTV Kitchener.

Paramedics transported the man to a local hospital, where he was pronounced dead, police said. The girl was treated at the scene.

Greg Baker was canoeing with his family when he saw someone in distress on the water.

"We realized that there was somebody in distress, so I jumped out of our canoe, swam over and then we tried to help," Baker told CTV News.

He added that the man appeared to have been in the water for quite some time.

Police are asking anyone who witnessed the incident to contact them at 1-888-310-1122.
