A major sponsor of Adrian Liu and Derrick Ng pulled out because the Vancouver duo lost major points they needed to qualified for the Olympics Games.
Ng says he and Liu can't afford the $40,000 bill to compete in nearly 18 other tournaments to make up the qualifying points, so they've started a crowdfunding campaign online.
"It was pretty devastating to hear our sponsor was pulling our funding," said Ng. "It was another big blow for us."
The pair were disqualified because Badminton Canada mistakenly entered them into another tournament that overlapped with the Games, which is in violation of a Badminton World Federation regulation.
Ng says he's asked Badminton Canada for help. He says officials told him the organization will help if it can, but there's no guarantee.
CBC News was unable to reach Badminton Canada.
More than $3,600 has been raised as of Tuesday at 7:30 a.m. PT.
"It means a lot to us, we never really knew how much people cared," said Ng. "We can't do it without them."
