The body of the Lake Erie victim, Walter Santos, was found at about 9:25 a.m. on Monday, a day after he went swimming with his two children at Long Point Provincial Park in Norfolk Country and disappeared.
His body was found about six kilometres east of where he went missing and about 40 metres out in the water.
An autopsy has been scheduled.
Man went into water wearing life-jacket
Meanwhile, a search continues for an Ajax man who went missing after his canoe capsized on Lake Ontario on Sunday night.
Durham Regional Police say that the 26-year-old man was reported missing at about 10:30 p.m.
The missing man had been paddling in a canoe with another man when it capsized. However, the other man made it to shore.
Police say the missing man was wearing a life-jacket when the canoe overturned. Both the canoe and the life-jacket have been recovered.
They've searched by air and by water, as far as 10 kilometres from shore.
Also Sunday, two brothers died in Toronto after they were found without vital signs in an east-end beach area.
90% of drowning victims in 2012 have been men
Experts told CBC News the number of incidents this weekend is likely due to the good weather and the sheer number of people in the water.
All of the victims this weekend were males. Ninety per cent of drowning victims in 2012 have been adult men.
"Men just take more risks," Barbara Byers of the Lifesaving Society said of those numbers. "They take more risks when they're cycling, when they're driving, when they're skiing, when they're snowboarding. It's just part of the male thing I guess, the testosterone."
Glen Turpin of the Ontario Volunteer Emergency Response Team warned that water temperatures are a factor even in the warmest months.
"You can survive for quite some time but hypothermia does become an issue, absolutely, in the summer," he said.
Turpin said it doesn't matter how strong swimmers think they are.
"Mother Nature is a fickle creature and you've gotta respect the water, you really do," he said.
