Steve Molitor (34-3), who held the International Boxing Federation super-bantamweight title twice, said Tuesday he has retired from the ring.
"I'm more about being a father now," said the 32-year-old father of three. "We live quite a bit west of Toronto now, so training full time is not an option."
The Sarnia, Ont., native was Canada's most successful boxer from outside Quebec in the past decade.
Molitor won the IBF belt with a victory in England over Michael Hunter on Nov. 10, 2006 and defended it five times before losing in four rounds to Celestino Caballero.
He won the title back by defeating South African Takalani Ndlovu for the second time in his career in 2010. The five-foot-seven battler defended it once more against Briton Jason Booth before a loss in his third meeting with Ndlovu in South Africa.
He had one more victory over Sebastien Gauthier in Quebec City before losing his final bout, which was for the Commonwealth title, in six rounds to Carl Frampton in Belfast, Northern Ireland, in September.
At his peak, Molitor made Casino Rama near Orilla, Ont., his home base and his fights were broadcast regularly on national television.
"Those are things you dream of: being recognized everywhere you go and winning a world title," he said. "That's something I always wanted and I got to do it twice."
He will do some work for one of his sponsors, recycling firm Triple-M Metal, but mostly he wants to relax. He said he may do some coaching later on, but for now: "I need to have a couple of years away from the sport."
