Club 70 was first located on 101 St. and 106 Ave., in the basement of a Greek restaurant.[3] When the owner realised that gay people were meeting there, he evicted them.[4] Because personal information of the members, such as names and addresses, had been left in the building, a few members broke in to remove them and prevent their members from being outed.[1] Only gays and lesbians were allowed to be members, and bringing a straight guest lead to a 30-day suspension.[1]
The club reopened a month later on 102 Ave. and 106 St.,[3] where it hosted themed nights and performances which were advertised in the Club 70 News newspaper, which also published more political articles.[1][2] Several famous drag queens including Millie performed there.[3] There were often incidents of homophobic violence outside the club.[4] Because of the difficulty in obtaining a liquor license, the club could only serve alcohol a few nights a week.[5] Patrons recall that the police frequently checked the premises to ensure that there was no liquor on dry nights.[2]
In the late 1970s, the club was also used as a drop in centre by the Gay Alliance Toward Equality (GATE).[1] It closed in 1978 due to financial struggles and the availability of other bars like Flashback and The Roost.[1] The independent art gallery Latitude 53 now occupies the building.
