The neighbourhood originated as the small lakefront town of Port Union in the 19th century, within the area now known as West Rouge, until 1974 part of the Township of Pickering.

Since the 1990s, the industrial lands along the waterfront have been transformed into new subdivisions, along with a paved walkway and bike path along the shore of Lake Ontario.

In 1974, as part of the municipal government reforms that introduced the Regional Municipality of Durham, the West Rouge area of Pickering (bordered by Port Union Rd in the west, the Rouge River in the east, and Twyn Rivers Drive in the north) was annexed by Scarborough, which in turn was amalgamated into Toronto in 1998.

Sir Oliver Mowat Collegiate Institute is a TDSB secondary school established in 1970.
