Maggie's provides education and support to sex workers in their efforts to live and work with safety and dignity.

Maggie's is the first sex-worker-run education project in Canada. The project provides information about health promotion, AIDS and STD prevention, Canadian law, and dangerous clients to sex workers. Maggie's was founded in 1986 and is an incorporated Ontario non-profit charitable organization, registered for tax exemption status with Revenue Canada. Maggie's has been funded by the Toronto Department of Public Health, the Ontario Ministry of Health, Health Canada and private donations. Maggie's at one time administered an annual budget of $380,000. Maggie's, the only organization of its kind in Canada, has been a model for sex worker peer-education projects, internationally. Maggie's membership is open to sex workers who support the group's goals. Maggie's offers non-voting membership for non-sex workers too.
