Venue manager Betony Garner says a toonie was buried under the finish line on The Mall, thanks to Canadian Stephanie Jones who is a member of the venue team.
Alas, the lucky toonie did not deliver a medal.
Ryder Hesjedal was 63rd in the men's road race Saturday and Canadians went 12th, 27th and 32nd in the women's race Sunday.
Canadian coins have been hidden in the past for luck, most notably at the 2002 Winter Olympics when a loonie was put under the playing surface by a Canadian ice-maker. Canada won men's and women's gold and the coin was later given to the Hockey Hall of Fame.
A loonie was also hidden at the IIHF World Hockey Championships the next year when Canada won gold.
The coin trick did not work for Canada at the 2003 Rugby World Cup in Australia.
