The 28-year-old Calgarian raced for her country at the Winter Olympics in Sochi, Russia, last year and finished seventh in her Olympic debut. The Canadian Olympic Committee commissioned commemorative rings for each athlete on the team.
Reid was not home Monday evening when thieves broke into the northeast house she shares with a cousin who was also away.
Her Olympic ring and her grandmother's pearl and diamond ring were the most precious items taken.
Reid, a bronze medallist at the 2013 world championship, says she called police immediately.
"When I saw those two rings were gone, I was just shocked," Reid told The Canadian Press.
"It's pretty devastating and upsetting to have my Olympic ring taken. It was something I worked for 11 years to earn. I wore it really proudly.
"My grandmother's ring was almost even more upsetting because I don't even feel it's really mine. It was a gift that she gave to me that is meant to be passed through our family. Both rings are things I can't really put a monetary value on."
The Maple Leaf and the Olympic rings adorn the outside of her Olympic ring that has "Sochi 2014" engraved on the inside. Her grandmother's ring is set with five pearls and diamonds on either side of each pearl.
