The home of the Deputy Warden of Kingston Penitentiary, then a minimum security prison and a halfway house. A Federal Heritage Building protected by Part 1V of the Ontario Heritage Act. The designation covers the exterior and interior of the residence. Residents of the Isabel MacNeill house were opposed to the closure of the property: House of Commons Ottawa April 18, 2007 Mrs. Irene Mathyssen (London-Fanshawe, NDP.) "Mr. Speaker, the government recently announced the closure of Canada's only minimum security prison for women. The Isabel McNeill House provides a transitional environment for incarcerated women offenders. It provides training to enhance their employment skills.
The inmates at the prison had to take the government to court and challenge the closure under the Charter of Rights and Freedoms. This is an equality issue and another example of the government's disregard for the welfare of women."
