The Andrew Mercer Reformatory for Women was the first women's (16 years of age or older) prison in Canada, opened in 1872.
The original Mercer Reformatory superintendent's house survives at Fraser and King. The site of the old reformatory is Lamport Stadium, and all that remains is the original superintendent's house at the corner of King Street and Fraser Avenue.
