The Toronto native was chosen 102nd overall by the Pittsburgh Penguins in 1977 while he was in the midst of a fine OHA career with the Pittsburgh Penguins and Sault Ste. Marie Greyhounds. In 1978-79, he looked solid in 28 games as a rookie and became a fan favorite at the "Igloo." Two years later, he won 25 games and nearly led his team to a huge first round upset over the New York Islanders.

In June 1981, the Hartford Whalers signed him as a free agent. After toiling admirably in 55 games for the mediocre club in 1981-82, Millen represented Canada at the World Championships. In 1983-84, he led the NHL with 60 appearances while helping Hartford become more respectable in the NHL standings.

Millen joined the St. Louis Blues in February 1985 following a major trade that also involved Mike Liut. He formed a solid goalkeeping tandem with Rick Wamsley and helped the club reach the semifinals in 1986. In 1988-89, Millen registered an NHL-high six shutouts along with 22 wins. Late in his career, the popular backstopper spent time with the Quebec Nordiques, Chicago Blackhawks, and Detroit Red Wings before retiring in 1992. After ending his career, Millen remained in the public eye as an analyst with CBC's "Hockey Night In Canada".
