TORONTO - Canadian swimmer Zack Chetrat will have his Pan Am medal upgraded to silver while teammate Alec Page and distance runner Rachel Hannah will receive bronze medals after a pair of Peruvian athletes were disqualified due to doping infractions.

The Canadian Olympic Committee was informed of the redistribution of medals by the Pan American Sports Organization after the conclusion of the anti-doping process, the COC said Thursday in a release.

Hannah gets the third-place result in the women's marathon.

"You think about how, in the moment, it would have been really special to have been up there on that stage (in the medal ceremony), so it is disappointing," Hannah said. "But it's a really nice surprise after the fact. And the fact that in Canada, with our process with Athletics Canada and drug testing, we are routinely tested, it keeps our sport clean on our end so I'm grateful for that too."

Chetrat moves into second place in the men's 200-metre butterfly while Page takes third in the same event.

"The experience of a home Games will be a memory I never forget," Page said in a statement. "It's great to be recognized and receive an honour like this, but the true honour was representing my team and my country at a home Games. That experience I'll always carry around my neck."

Gladys Tejeda originally won marathon gold in two hours 33.03 seconds. She was stripped of the result due to a failed doping test administered during the Games, Athletics Canada said in a release.

Specifics on the infraction weren't immediately available.

Adrianna Da Silva of Brazil (2:35.40) will be upgraded to gold and American Lindsay Flanagan (2:36.30) will move up to silver. Hannah (2:41.06) will receive her bronze medal on Saturday in Kingston, Ont., during a special ceremony at the Canadian cross-country championships.

"It will be fantastic to receive the medal among Canada's best distance runners, all in one spot," said Hannah, who is racing at the cross-country nationals.

Swimmer Mauricio Fiol was the other disqualified athlete, a Swimming Canada spokesman said. He tested positive for the banned steroid stanozolol and was suspended from the Peruvian team on July 17.

Fiol finished just 0.14 seconds behind gold medallist Leonardo De Deus of Brazil, who finished first in one minute 55.01 seconds. Chetrat moves into second with a time of 1:56.90 and Page takes third in 1:58.01.

Page will receive his medal Friday at the Saanich Commonwealth Place pool in Victoria. Plans for Chetrat's ceremony have not yet been finalized.

"I am thrilled to see that Zack, Alec and Rachel are finally getting the silver and bronze medals they won and deserve," said Canadian chef de mission Curt Harnett. "We congratulate them all for their outstanding accomplishments and the honour they bring to their sport and our country."

The changes bring Canada's final medal tally at the Pan Am Games to an all-time Canadian record of 219 medals: 78 gold, 70 silver and 71 bronze.

Hannah's bronze pushes the Canadian track and field team's total to 27 medals, an all-time best result for the team. The previous team best was 24 medals at the 1967 edition of the Pan Ams.

"Congratulations to Zack for his silver medal and to Alec and Rachel for their bronzes, all so rightfully earned," said COC president Tricia Smith. "I congratulate them for their achievements. The COC is resolute in its determination to protect clean athletes from doping.

"While the situation that prevented them from getting those medals in the first place is disturbing, we are pleased it was rectified. It underlines the need to be ever more vigilant in protecting the integrity of sport."
