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

Prior to European settlement, Delta's flatlands and coastal shores were inhabited by the Tsawwassen First Nation of the Coast Salish.

In 1879, the area was incorporated as a municipality, named "the Corporation of Delta", and the village of Ladner was made as its administrative centre.

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.

About 45% of Delta's population are visible minorities, of which there are approximately 28,000 South Asians, 9,700 Chinese people, and 3,700 Filipinos.

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.

Delta's flat, fertile land has made it one of the most important agricultural areas in Greater Vancouver.

North Delta is also home to the Burns Bog, 40 km2 (15 sq mi) of natural wetlands that are important for wildlife.

[16] 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.

As of the 2021 Federal general election, Delta's seat is held by Carla Qualtrough of the Liberal Party.
