Toronto police have recovered the bodies of two boaters who went missing in Lake Ontario on Sunday.

Authorities were alerted when the two men, aged 52 and 72, left Bluffer's Park Marina together for Lake Ontario on Sunday morning and didn't return at lunch as planned.

Police said strong winds made for large waves of up to nearly a metre in height, which may have overpowered the pair's four-metre long aluminum boat.

A fishing boat found the first man's body, police said, while the other was found in the water near the marina.  

Police said both bodies lacked vital signs, but paramedics attempted to revive both men with CPR.

A friend of one of the victims who was helping with the grim search said he warned one of the men about the dangerous conditions on the water. 

"He should have never went out. It's too bad," he said, noting his friend brushed off his warnings because he wanted to go fishing. 

Others who knew the men also went to the marina, where several wept as police recovered the bodies and put them into ambulances.
