Tsawwassen is a suburban, mostly residential community on a peninsula in the southwestern corner of the City of Delta in British Columbia, Canada. It provides the only road access to the American territory on the southern tip of the peninsula, the community of Point Roberts, Washington, via 56th Street. It is also the location of Tsawwassen Ferry Terminal, part of the BC Ferries, built in 1959 to provide foot-passenger and motor vehicle access from the Lower Mainland to the southern part of Vancouver Island and the southern Gulf Islands. Because Tsawwassen touches a shallow bank, the ferry terminal is built at the southwestern end of a 3 km (1.9 mi) causeway that juts into the Strait of Georgia. Boundary Bay Airport, a major training hub for local and international pilots which also provides local airplane and helicopter service, is ten minutes away. The Roberts Bank Superport is also nearby.

Delta is a city in the Lower Mainland region of British Columbia, Canada, as part of Greater Vancouver. Located on the Fraser Lowland south of Fraser River's south arm, it is bordered by the city of Richmond on the Lulu Island to the north, New Westminster to the northeast, Surrey to the east, the Boundary Bay and the American pene-exclave Point Roberts to the south, and the Strait of Georgia to the west.
