On 5 February 1981, Toronto police carried out Operation Soap, raiding four gay bathhouses and arresting 286 men in one of the largest mass arrests in the city's history. The response was immediate: the following night, roughly 3,000 people marched through downtown Toronto demanding an end to the harassment. It became a defining moment for Toronto's queer community and its Pride movement — one that's widely remembered today, among activists and historians alike, as "Canada's Stonewall."
