Located at the eastern edge of the city between the mouth of Highland Creek and the Rouge River, this waterfront park provides 13.5 hectares of green space and connects the Port Union community to Lake Ontario. It features 3.8 kilometers of continuous waterfront trail, great views of Lake Ontario and its shoreline, a new pedestrian bridge over Highland Creek and trail connections north into the Highland Creek watershed. At the city's edge, the existing bridge over the Rouge River connects the park to the City of Pickering.

This park was created by Toronto and Region Conservation Authority (TRCA) with funds provided by Waterfront Toronto. It was developed in two phases, the first completed in 2006 and the second in 2012. It provides important recreational access to the waterfront, protects the shoreline, supports important terrestrial and aquatic habitats and offers environmental, economic and social benefits to the Port Union community and broader region.
