With the dissolution of Vancouver Kingsway, Waddell instead contested the newly established riding of Port Moody—Coquitlam in the 1988 federal election. He was elected MP for that riding,[15] and served as NDP's justice critic in the 34th Canadian Parliament.[1] Following the resignation of Ed Broadbent as federal NDP leader in 1989, Waddell joined in the leadership race;[16][17] he placed sixth in the first ballot before withdrawing.[18] He sought re-election in Port Moody—Coquitlam in the 1993 federal election, but came in third with 21% of the vote, ending his 14-year career as MP.[15][19]
As a BC NDP candidate in the 1996 provincial election, Waddell was elected to the Legislative Assembly of British Columbia to represent the riding of Vancouver-Fraserview, winning by 380 votes.[20] He was appointed Minister of Small Business, Tourism and Culture in February 1998 by PremierGlen Clark.[8] As minister, Waddell was responsible for the first Olympic bid for the 2010 Winter Olympics in Vancouver and Whistler, beating out well financed Calgary and political favourite Quebec City.[9] He brought in a film tax credit, which created a billion dollar film industry in BC.[21] He subsequently served as Minister of Environment, Lands and Parks under Ujjal Dosanjh from November 2000 to April 2001.[8][22] He lost the Vancouver-Fraserview seat to Liberal candidate Ken Johnston in the 2001 provincial election.[20]
After leaving politics, Waddell worked as a consultant in environmental, governmental and aboriginal affairs.[10][28] He was given the honorary title of Queen's Counsel in December 2013 for his exceptionally meritorious contribution to law.[13] He also became a documentary film producer, winning the Best Producer Award in the 2016 Beverly Hills Film Festival alongside Dylan Playfair and Robert Lang for their film The Drop: Why Young People Don't Vote.[29][30]
