Federal politics
Young ran for the House of Commons of Canada as an independent candidate in the 1974 federal election, in the Toronto riding of Parkdale. He received 144 votes, finishing well behind winner Stanley Haidasz of the Liberal Party.
He was elected to the House of Commons in the 2008 federal election, defeating Liberal incumbent Bonnie Brown in Oakville. On May 2, 2011, Young was reelected in Oakville with a larger majority of 12,178 votes, defeating local Oakville councillor Liberal Max Khan. He served as a backbench supporter of the Stephen Harper government.
In December 2014, Young introduced a Private Member's Bill called An Act Respecting the Prevention of Potential Health Risks from Radiofrequency Electromagnetic Radiation. The act which was co-written by Canadians for Safe Technology would have forced manufacturers of devices emitting electronic signals to place warning labels on the packaging. The bill did not get past first reading.
As a member of the Standing Committee on Health, Young devoted much of his time in Parliament to speaking out about the dangers of marijuana and the deaths it is allegedly directly responsible for. Young contended that marijuana legalization would normalize its use among Canadian youth, who currently lead the developed world in marijuana consumption. Young's argument that legalizing marijuana would still allow minors access because minors clearly have access to tobacco and alcohol despite age restrictions, had the unintended consequence of also being an argument against the legalization of the latter two substances, as noted by pundits.
Young was acclaimed as the Conservative candidate in Oakville riding for the 2015 Canadian federal election. At an all candidates' debate hosted by the Oakville Chamber of Commerce on October 6, 2015, when asked how he and his party would create employment for young Canadians, Young changed the subject stating one of the biggest problems Canada's youth have is drugs. The move provoked a groan from the crowd. Young also alleged during the campaign that the Liberal Party would create brothels if elected.
In the 2015 federal election, he lost to Liberal candidate John Oliver by 4,480 votes.
He attempted a comeback in the 2019 federal election, but he lost to Liberal candidate Anita Anand. After the 2019 election, Young supported attempts to remove Andrew Scheer as leader of the Conservative Party. Speaking with The Globe and Mail, Young described Scheer as "a nice man," but that during the election he didn't find a way to connect affirmatively with voters. Young said that he first noticed this issue during the campaign. "Not one voter ever said to me, 'Gee, I really like your leader,'" Young said. "Many voters said various versions of the opposite." He also said that "A partial victory is still a loss" (the Conservatives had gained seats but too few to replace the Liberals as the governing party), and that he believed Peter MacKay could "connect with people" and that he was "principled." He said about Scheer that "This isn’t a Rotary club, this is our country, and no one deserves a second chance because people like them."
