A Cornerstone of Portsmouth Village

Pending approval by the City of Kingston.

Our Vision

Union Park Kingston will reimagine the site of the former Prison for Women.

The proposed plan is to create a vibrant mixed-use neighbourhood for the benefit of all existing neighbours in Portsmouth, Kingstonians in general, and the hundreds of people that will live and work at Union Park.

Union Park Kingston will be located on an 8.1-acre site near Portsmouth Harbour adjacent to the Correctional Service of Canada Museum and steam plant, Duncan McArthur Hall (Queen’s University), and the Kingston Penitentiary. It is situated on on the traditional homeland of the Anishinaabe, Haudenosaunee and the Huron-Wendat which are also occupied by the Métis, Inuit, and other Indigenous peoples.
