Fortin suggested representing another country is an avenue she might explore after she lost to Mary Spencer at last week's Canadian women's boxing championships.
"She has to find another country that wants her, apply for citizenship, get the citizenship, make their national team," Robert Crete said Wednesday.
Fortin lacks the dual citizenship other athletes have used to their advantage and, if the country picked were in Europe, she would have to qualify there as well as nationally before heading to the world championships in China to earn an Olympic berth, he added.
"I know that she's not too happy that she lost and her Olympic dream is gone ... (but) when you lose, you lose and you move on."
Spencer won the 75-kilogram class and is currently ranked No. 1 in the world as she prepares to head to China this spring to try to qualify for the summer Olympics. Women's boxing is making its debut at the London games.
Crete says Fortin's claims of biased judging were not substantiated. She was leading going into the third round and she and her manager appealed the decision after the fight.
"We reviewed the scoring and there was no abnormality in the five officials and she clearly lost her competition," Crete said.
Spencer and Fortin are both former world champions.
Spencer, now living in Windsor, Ont., has held three world titles, two at 66 kilograms and one at 75 kilograms. Fortin, from Saint-Nicolas, Que., has held two titles at 69 kilograms.
The former roommates, friends and sparring partners had to compete against each other in the 75-kilogram class last week in Glace Bay, N.S., because only three weight classes were approved for women at the Olympics — 51, 60 and 75 kilograms. Men's boxing has 11 weight classes at the Games.
