The Andrew Mercer Reformatory for Women was a women's (16 years of age or older) prison in Toronto, Ontario, Canada. At various times, the facility was also known as the Mercer Complex, Andrew Mercer Reformatory for Females, and Andrew Mercer Ontario Reformatory for Females.
Located on King Street West in Toronto, Ontario, the Mercer Reformatory opened in 1880. The complex was composed of two institutions: The Mercer Reformatory for adult women and the Industrial Refuge for Girls for those under 14. It would later include facilities for drug treatment and psychiatric disorders. The complex would stand until 1969, when it was demolished and replaced by other institutions.
