Canada Lands Company never wanted to save the Prison for Women
At least one city politician in Kingston, Ontario tried to save the Prison for Women, he or she wanted to designate the property a heritage site under Part 1V of the Ontario Heritage Act, but:

     "The City received an objection to the notice of intent on September 26 2006 from the then property owner, Correctional Services Canada/Canada Lands Company. A withdrawal of the objection was received by the City on April 29 2008. An important aspect of the withdrawal was the City's inclusion of a provision within the designation by-law stating that the by-law would not be in force while the site was federally owned."
