Out, became Canada's first LGBT television series when it aired on Maclean-Hunter cable in Toronto in 1972. In 1973, several Canadian cities held gay rights events in conjunction with Pride Week 1973. In 1974, four lesbians who became known as the "Brunswick Four" were involved in a historic incident in Toronto, Ontario. The four were evicted from the Brunswick House, a working-class beer hall on Bloor Street, and subsequently arrested, and three were later tried in Ontario Court for obstruction of justice. Two of those three women were acquitted in May 1974, but one, Adrienne Potts, served three months probation.

The same year, the Canadian Immigration Act was amended, removing a ban on homosexual men as immigrants. 1980s 1980–1984 On February 5, 1981, four gay bathhouses in Toronto were raided by the Toronto Police Service in Operation Soap. The event is now considered one of the crucial turning points in Canadian LGBT history, as an unprecedented community mobilization — now regarded as the Canadian equivalent of the 1969 Stonewall riots — took place to protest police conduct. One of the protest marches during this mobilization is now generally recognized as the first Toronto Pride event. In 1982, Canada patriated its Constitution, to which it added the Canadian Charter of Rights and Freedoms. Section 15 of the Charter, which guarantees equality "before and under the law" and the "right to the equal protection and equal benefit of the law without
