“The series ran for five seasons (2000 to 2005 on Showtime and 2001 to 2005 on Showcase). It was believed by fans that the show could have run for another year (most of the cast originally had six year contracts but according to one rumor the contracts were renegotiated to five years after the first season).
However, Showtime was concerned about the rising production costs due to the strength of the Canadian Dollar. Some of the cast, however, felt that Showtime didn't want to be known as a "gay only" network so they cancelled the show. Publicly, at least, Ron Cowen and Daniel Lipman both stated that they didn't feel there were really any further stories that they could tell. Randy Harrison (Justin) was reported as saying that had the series gone into a sixth season, he would not have been part of it.”
