Maggie's Toronto Sex Workers Action Project is an organization run for and by sex workers. Their mission is to assist sex workers in their efforts to live and work with safety and dignity. Founded in 1986, Maggie's is one of Canada's oldest sex worker justice organizations. They work from a harm reduction perspective and believe that sex workers must control their own lives and destinies. The organization formally adopted the name "Maggie's Toronto Sex Workers Action Project" in 2009 and became a registered charity in 1991.

Maggie's focuses primarily on serving sex workers in Toronto and the Greater Toronto Area (GTA). They specifically support sex workers in Toronto's downtown east end through various programs. As they approach their 40th anniversary in 2026, Maggie's continues to offer services across Toronto and the GTA. Their office is located at 526 Richmond Street East in Toronto.

Program highlights include drop-in sessions, case management, street outreach, and community-specific supports. They offer weekly drop-ins on Wednesdays, specialized Indigenous drop-ins, and groups for trans/non-binary and male sex workers. Maggie's provides safer sex and drug use materials, information, and education. They also offer legal services, emergency food efforts, therapy services, and more. Their work includes advocating for human rights and the decriminalization of sex work. Maggie's operates with an experientially-led model that prioritizes sex work experience and knowledge.
