Elected to represent the
riding of
Markham—Unionville in the
House of Commons of Canada in the
2021 Canadian federal election, he served as Parliamentary Secretary to the Minister of Diversity and Inclusion. During the
2025 federal election, it was revealed that Chiang remarked at a Chinese-language media news conference in January that
Joe Tay, who was then seeking the Conservative nomination in
Markham—Unionville, should be reported to the Toronto Chinese Consulate in exchange for a 1 million HKD bounty that was placed by the Hong Kong police. Chiang later apologized for the comments by calling them "deplorable." He also issued another statement saying it should never happen again and that he reached to Tay for a personal apology. Tay rejected Chiang's apology stating it was insufficient. The
Royal Canadian Mounted Police later opened an investigation to see if Chiang's comment broke the law after
Hong Kong Watch filed a complaint. He was replaced by
Peter Yuen who was defeated by Conservative candidate
Michael Ma in the election. ==Personal life==
