A cornerstone of Portsmouth Village

Union Park Kingston will reimagine this site’s potential by creating a vibrant mixed-use neighbourhood for the benefit of all existing neighbours in Portsmouth and Sydenham, Kingstonians in general, and the hundreds of people that will live and work at Union Park.
This vibrant new planned community in the Portsmouth Harbour area will provide much needed housing, jobs, and small commercial and retail services allowing nearby seniors to age in place and creating live-work-play-age opportunities while respecting the heritage and history of the site and the Portsmouth area.

The Union Park proposal includes residential condominium units, a park and connecting pathway, a hotel for short-term and extended stays, a senior’s retirement residence, a public art wall, and a healing garden in collaboration with the P4W Memorial Collective. If approved, construction would take place in multiple phases over several years.

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.
