Creekway Park will become a critical part of the stream network connecting Hastings Park to the shore of Burrard Inlet in New Brighton Park.
As part of the Hastings Park 2011 Master Plan, the City made a commitment to pursue the development of a stream connection through Creekway Park. The proposed constructed watercourse and wetland provides a functional amenity of ecological value, connecting the Sanctuary with Burrard Inlet. To some, the reference to this historic stream provides a connection to the past.

Due to variable flow, impaired water quality, and fishpassage barriers, Creekway Park will not support native salmon and trout populations, however, it will be a biologically rich habitat:
