Delta is a city in the Lower Mainland region of British Columbia, Canada, and 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 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.

Encompassing the nearby Annacis Island, Deas Island and Westham Island, Delta is mostly rural and officially composed of three distinct communities: North Delta, Ladner and Tsawwassen.

History Prior to European settlement, Delta's flatlands and coastal shores were inhabited by the Tsawwassen First Nation of the Coast Salish. The land was first sighted by Europeans in 1791, when Spanish explorer Lieutenant Francisco de Eliza mistook the area for an island and named it "Isla de Cepeda". The first European settler in Delta was James Kennedy who pre-empted 135 acres in what later became Annieville in February 1860. Thomas and William Ladner, began farming the area named after them in 1868. Farming and fishing helped the community grow quickly over the next few decades. In 1879, the area was a municipality, named "the Corporation of Delta", and the village of Ladner was made as its administrative centre.

Due to its geography, Delta was a relatively isolated community. The completion of the George Massey Tunnel in 1959 linking Ladner to Richmond and Vancouver along with the opening, in 1960, of the Tsawwassen Ferry Terminal and the Highway 99 being rerouted from the King George Highway in Surrey in 1962 to a new route through Delta, ended Delta's isolation and resulted in a massive 400% population growth over the next 20 years. The 1986 completion of the Alex Fraser Bridge connecting North Delta to New Westminster and Vancouver also helped Delta's growth.

On 22 September 2017, at the request of Delta's council, the Government of British Columbia changed the name and classification of the Corporation of Delta to the City of Delta.

Neighbourhoods Delta comprises three distinct, geographically separate communities: North Delta (pop: 60,769) is home to over half of Delta's population. It is a largely suburban area in north-east Delta bordered by the Burns Bog and Surrey. Ladner (pop: 23,047) is a 19th-century fishing village in northwest Delta that has expanded into a suburb. Fishing and farming are important industries. Ladner Trunk Road is its main street. Tsawwassen (pop: 22,160) is a suburban community in the southwest Delta that calls itself the sunniest place in Metro Vancouver. Luxury waterfront homes line Tsawwassen's coast. Tsawwassen is also home to the busy Tsawwassen Ferry Terminal which links the mainland to Vancouver Island and the Gulf Islands. Tsawwassen, together with Ladner are also known as South Delta.

Geography

Delta is located south of Vancouver and north of the Canada–US border at Peace Arch, Surrey. It is bordered by water on three sides: The Fraser River to the north, the Georgia Strait to the west and Boundary Bay to the south. At , Delta is the largest municipality in the GVRD; the second largest is its neighbour to the east, Surrey, at .

Delta's flat, fertile land has made it one of the most important agricultural areas in Greater Vancouver. The Agricultural Land Reserve regulations preserve most of this land for agricultural use, preventing its conversion to suburban housing. North Delta is also home to the Burns Bog, of natural wetlands that are important for wildlife.

Delta includes Annacis Island, an industrial island reached via the Alex Fraser Bridge, which connects Delta with Richmond and New Westminster. Delta also includes a peninsula on the east side of the Fraser River at Delta's northern city limits, which is only accessible via Surrey.

Climate Delta is known for its relatively dry and sunny climate compared with other locations in Metro Vancouver. For example, it receives nearly 40% ( from 1981 to 2010) less precipitation than downtown Vancouver ( at Vancouver Harbour CS from 1971 to 2000) and just over half of that of North Vancouver ( at North Vancouver 2nd Narrows from 1981 to 2010). It has a warm-summer Mediterranean climate (Köppen Csb) with cooler summers and milder winters than other areas on the Canada–U.S. border, and features some of the mildest winters and lowest diurnal temperature variation in Canada.

Government and politics Delta is governed by the Delta City Council, led by a Mayor and six Councillors, elected for four-year terms, and there is also an elected school board. The current mayor is George Harvie. Unlike most communities in Canada, but like Vancouver and Richmond, Delta has a system of locally based election slates such as TriDelta, IDEA, One Delta, Delta Residents Association, Delta Connect, DIVA, Independents Working For You, and Achieving For Delta.

In the House of Commons of Canada, Delta is part of the Delta electoral district. As of the 2025 Federal general election, Delta's seat is held by Jill McKnight of the Liberal Party. In the 2024 provincial general election, the North Delta seat went to Ravi Kahlon of the British Columbia New Democratic Party while the South Delta seat went to Ian Paton of BC Conservative Party.

Delta, unlike most Lower Mainland municipalities, has its own police department.

Former Delta mayor Lois Jackson served from 1999 to 2018 and since 1973 has had a seat on the Delta Council. Jackson was elected to council again in 2018.

Power In Delta is BC Hydro's Arnott Substation, the mainland terminal of the southern AC transmission connections providing power to Vancouver Island, and the former converter station for the HVDC Vancouver Island circuits.

Transportation

Public transportation in Delta is a bus system provided by TransLink. There is no rapid transit system in Delta, though the SkyTrain system in Surrey comes within of the city's borders. Delta is a major transportation hub for the Lower Mainland. Most vehicles leaving Vancouver for the United States pass through Delta's borders. Many vehicles destined for Vancouver Island use the Tsawwassen ferry terminal in Delta. Highway 99 links Richmond to Delta via the George Massey Tunnel, built in 1959. North Delta is linked to New Westminster and Richmond by Highway 91 and the massive Alex Fraser Bridge (opened in 1986). Delta is linked to Surrey, Langley, and all points eastward by Highway 10. Traffic congestion during rush hour is quite common, although improvements are being made to Highway 91 interchanges at 72 Ave to remove a traffic light as well as the ramps from Nordel Way. Highway 17 in Delta provides a connection to the Tsawwassen B.C. Ferry terminal, which provides car ferry connections to Vancouver Island and the Gulf Islands. In December 2013, north of the current junction with Deltaport Way, Highway 17 will be rerouted upon completion of the "South Fraser Perimeter Road", and will primarily run parallel to River Road through Tilbury and North Delta to all points east. The remaining stretch of Highway 17 north of that point will be renamed Highway 17A. River Road is also another connector through the municipality. River Road starts in Surrey and heads westbound through North Delta, under the Alex Fraser Bridge, north of Burns Bog, and then terminates at 62B Street, which then turns into Highway 17A. Like River Road, the western communities of "South Delta" (Ladner and Tsawwassen) are linked to North Delta and communities to the east by Ladner Trunk Road; east of its crossover of Highway 91, the road becomes Highway 10. 56th Street is another major artery in the community, bisecting the Tsawwassen region; it is the only road leading into the community of Point Roberts, south of the Canada–US border. Delta is also home to Boundary Bay Airport, Canada's seventh busiest airport by aircraft movements. Boundary Bay Airport is primarily used for private aircraft, commercial charters, and flying lessons.
