June to September is Pride Season in Canada, a time to celebrate 2SLGBTQI+ people (that is, people who are Two-Spirit, lesbian, gay, bisexual, transgender, queer, or intersex, or who use other terms related to sexual or gender diversity) and honour the contributions that they have made and continue to make.

During Pride, a wide range of parties, parades and other celebratory events take place across the country.

Historically, gatherings emerged from the first large-scale protests for 2SLGBTQI+ rights. In Canada, the first demonstrations took place in Ottawa and Vancouver in 1971. By 1973, Pride events were held in several major Canadian cities. Toronto’s Pride weekend in June is now among the largest Pride events in North America
