Younie ran for a seat in the Alberta Legislature in the 1979 Alberta general election in the electoral district of Rocky Mountain House. Younie ran for a second term in the 1989 Alberta general election but was defeated in a landslide by Laurence Decore who had become leader of the Liberals the previous year.
He finished a distant third place out of four candidates behind future Social Cr leader Lavern Ahlstrom and John Murray Campbell who won the district. He would make another attempt to win a seat by running in the 1986 Alberta general election. He won a hotly contested race in the electoral district of Edmonton-Glengarry by a safe margin defeating four other candidates.
He served as a member of the Legislative Assembly of Alberta for a single term from 1986 to 1989 and sat as a member of the New Democrats caucus when they held official opposition status.
