Lower Mainland

The Lower Mainland is a name commonly applied to the region surrounding and including Vancouver, British Columbia, Canada. As of 2016, 2,759,365 people (60% of British Columbia's total population), lived in the region; sixteen of the province's thirty most populous municipalities are located there.[1] Islands contained within rivers in the region are considered to be part of the Lower Mainland.

While the term Lower Mainland has been recorded from the earliest period of non-native settlement in British Columbia, it has never been officially defined in legal terms. The British Columbia Geographical Names Information System (BCGNIS) comments that most residents of Vancouver might consider it to be only areas west of Mission and Abbotsford, while residents in the rest of the province consider it to be the whole region south of Whistler and west of Hope.[2] However, the term has historically been in popular usage for over a century to describe a region that extends from Horseshoe Bay south to the Canada–United States border and east to Hope at the eastern end of the Fraser Valley.[3]

Climate, ecology and geology of the Lower Mainland are consistent enough that it has been classified as a separate ecoregion (the Lower Mainland Ecoregion) within the Ecological framework of Canada, used by both Federal and Provincial Environment Ministries.[4][5] The region is the traditional territory of the Sto:lo, a Halkomelem-speaking people of the Coast Salish linguistic and cultural grouping. There are two Regional Districts within the region, Metro Vancouver and the Fraser Valley.

The region is bounded to the north by the Coast Mountains and to the southeast by the Cascade Mountains, and is traversed from east to west by the Fraser River. Due to its consistency of climate, flora and fauna, geology and land use, "Lower Mainland" is also the name of an ecoregion—a biogeoclimatic region—that comprises the eastern part of the Georgia Depression and extends from Powell River on the Sunshine Coast to Hope at the eastern end of the Fraser Valley.[6]

One of the mildest climates in Canada, the region has a mean annual temperature of 9 °C with a summer mean of 15 °C and a winter mean of 3.5 °C. Annual precipitation ranges from an annual mean of 850 mm in the west end to 2000 mm in the eastern end of the Fraser Valley and at higher elevations. Maximum precipitation occurs as rain in winter. Less than ten percent falls as snow at sea level but the amount of snowfall increases significantly with elevation.[6]



Population history
Source: Statistics Canada

As of the 2016 census, the population of the Lower Mainland totals 2,759,385:

These figures are slightly inflated due to the inclusion of areas within the Regional Districts which are not normally considered to be part of the Lower Mainland, notably the lower Fraser Canyon and the heads of Harrison and Pitt Lakes, which are within the FVRD, and Lions Bay and Bowen Island, which are within the Greater Vancouver Regional District.

The population of the Lower Mainland was up 9.2 percent from the 2006 census. This is among the highest growth rates in the continent.


The Lower Mainland is among the most diverse regions in Canada. Europeans form just over 50% of the population, while other significant ethnic groups which dominate the Lower Mainland include Chinese (17.6%) and South Asians (12.2%).

Regional districts

Regional districts were first created across British Columbia in 1966–1967 to form bodies for inter-municipal coordination and to extend municipal-level powers to areas outside existing municipalities. Today, the Lower Mainland includes two Regional Districts: the Metro Vancouver Regional District and the Fraser Valley Regional District (FVRD). Both regional districts, however, include areas outside the traditional limits of the Lower Mainland. Metro Vancouver includes areas like Surrey and Langley that are geographically in the Fraser Valley.

The Metro Vancouver Regional District (MVRD) is made up of 21 municipalities. The MVRD is bordered on the west by the Strait of Georgia, to the north by the Squamish-Lillooet Regional District, on the east by the Fraser Valley Regional District, and to the south by Whatcom County, Washington, in the United States.

The Fraser Valley Regional District lies east of the Greater Vancouver Regional District, and comprises the cities of Abbotsford and Chilliwack, the district municipalities of Mission, Kent, and Hope, and the village of Harrison Hot Springs. It also includes many unincorporated areas in the Fraser Valley and along the west side of the Fraser Canyon (the Fraser Canyon is not in the Lower Mainland).

Regional district powers are very limited and other localized provincial government services are delivered through other regionalization systems.

Indigenous territories

The traditional territories of the Musqueam and Tsleil'waututh lie completely within the region; the southern portion of Squamish traditional territory is also in the region. Its claims overlap those of the Tsleil-waututh, Musqueam, and Kwikwetlem. Other peoples whose territories lie within the region are the Sto:lo, Chehalis, Katzie, Kwantlen, Tsawwassen, and Semiahmoo; many of their territories overlap with those of the Musqueam, and with each other. Many other peoples of the Georgia Strait region also frequented the lower Fraser, including those from Vancouver Island and what is now Whatcom County, Washington.

Sto:lo traditional territory, known as Solh Temexw in Halkomelem, more or less coincides with the traditional conception of the Lower Mainland, except for the inclusion of Port Douglas at the head of Harrison Lake, which is in In-SHUCK-ch territory, and the lands around Burrard Inlet.

Health regions

Health system services and governance in the Lower Mainland are provided by Vancouver Coastal Health, serving Vancouver, Richmond and the North Shore, and the mainland coast as far north as the Central Coast region, and Fraser Health, which serves the area of the Lower Mainland east of Vancouver and Richmond.[15]

Natural threats


The Lower Mainland is considered to have a high vulnerability to flood risk. There have been two major floods, the largest in 1894 and the second largest in 1948. According to the Fraser Basin Council, scientists predict a one-in-three chance of a similar-sized flood occurring in the next 50 years.[16]

In the spring of 2007, the Lower Mainland was on high alert for flooding. Higher than normal snow packs in the British Columbia Interior prompted municipal governments to start taking emergency measures in the region. Dikes along the Fraser River are regulated to handle about 8.5 m at the Mission Gauge (the height above sea level of the dykes at Mission). Warmer than normal weather in the interior caused large amounts of snow to melt prematurely, resulting in higher than normal water levels, which, nevertheless, remained well below flood levels.[17][18]

Flooding can cover much of the Lower Mainland. Cloverdale, Barnston Island, low-lying areas of Maple Ridge, areas west of Hope, White Rock, Richmond, parts of Vancouver, and parts of Surrey are potentially at risk. In 2007, the Lower Mainland was largely spared, although northern regions of the province, along the Skeena and Nechako Rivers, experienced floods. Climate scientists predict that increasing temperatures will mean wetter winters and more snow at the high elevations. This will increase the likelihood of snowmelt floods.[19]

The provincial government maintains an integrated flood hazard management program and extensive flood protection infrastructure in the Lower Mainland. The infrastructure consists of dikes, pump stations, floodboxes, riprap, and relief wells.[20]


While earthquakes are common in British Columbia and adjacent coastal waters, most are minor in energy release or are sufficiently remote to have little effect on populated areas. Nevertheless, earthquakes with a magnitude of up to 7.3 have occurred within 150 kilometres of the Lower Mainland.

Based on geological evidence, however, stronger earthquakes appear to have occurred at approximately 600-year intervals. Therefore, there is a probability that there will be a major earthquake in the region within the next 200 years.[21]

In April 2008, the United States Geological Survey released information concerning a newly found fault line south of downtown Abbotsford, called the Boulder Creek Fault. Scientists now believe this fault line is active and capable of producing earthquakes in the 6.8 magnitude range.[22]


Much of the Lower Mainland is vulnerable to explosive eruptions from the Garibaldi Volcanic Belt. Volcanoes in this zone are capable of producing large quantities of volcanic ash that may cause short and long term water supply problems for Lower Mainland communities.[23] All airports covered by the accompanying eruption column would be closed, heavy ash falls would damage electrical equipment and weak structures could collapse under the weight of the ash.[24]


The Lower Mainland's communities includes large cities in Metro Vancouver, and smaller cities, towns and villages along both banks of the Fraser River. Neighbourhoods within cities are not listed unless historically or otherwise notable and/or separate. Only some of the many Indian Reserves are listed.

Blanshard Peak

Blanshard Peak also known as The Blanshard Needle by local climbers is a distinctive rock pinnacle in Golden Ears Provincial Park that is visible from many places in the Lower Mainland. Named for the first governor of the colony of Vancouver Island, the name of the summit and area is the subject of some confusion due to the labeling of the entire Golden Ears Group on the published maps for the area. Mount Blanshard is the proper name of the Golden Ears massif, and later became attached by authors of climbing guides to the summit at the southern end of the group.

Cascade Falls Regional Park

Cascade Falls Regional Park is a regional park under the administration of the Fraser Valley Regional District in the Lower Mainland region of British Columbia, Canada. The park was originally 9.5 hectares in area but was expanded to a current 22 hectares. It has picnic tables and pit toilets, with various hiking trails and a walkway leading to a viewing platform over a large waterfall 30m in vertical drop, which is 15 minutes from the park's parking lot. It is located in the McConnell Creek area northeast of Mission, which gets its name from the former name of Cascade Creek, McConnell Creek, which was named for a logger in the area called Jack McConnell. Cascade Creek's outfall is into the southeast end of Stave Lake near Davis Lake Provincial Park.The park was first proposed in 1984 via studies commissioned by the Dewdney-Alouette Regional District and officially inaugurated on June 7, 1986. The land the park comprises was previously part of the Douglas Provincial Forest.Cascade Falls was featured in the final scene of the film Big Bully, as the location of a fight between characters played by Tom Arnold and Rick Moranis.

Chilliwack River Provincial Park

Chilliwack River Provincial Park is a provincial park in British Columbia, Canada, located on the north side of the Chilliwack River to the southeast of the City of Chilliwack in the province's Lower Mainland region.

When first established in 1961, the park comprised approximately 65 acres. Boundaries were decreased in 1970, then increased back to 65 acres later that year. The boundary was redrawn again in 2004, with the park now comprising 21 hectares.

Coquihalla Canyon Provincial Park

Coquihalla Canyon Provincial Park, popularly called the Othello Tunnels is a provincial park located near Hope, British Columbia focused on the canyon of the Coquihalla River and a decommissioned railway grade, now a walking trail, leading eventually to Coquihalla Pass. Originally part of the Kettle Valley Railway, five tunnels and a series of bridges follow a relatively straight line through the gorge, which is lined with sheer, flat rock cliffs.

The park was established by Order-in-Council as the Coquihalla Canyon Recreation Area, then upgraded and renamed with full provincial park status in 1997, at 151.3 hectares (374 acres) in size. It was expanded to its current 159 hectares (390 acres) hectares in 2004.

The park's rock cliffs and relatively close distance to Vancouver has resulted in many popular movies being filmed there. First Blood, Shoot to Kill, Far from Home: The Adventures of Yellow Dog, Cabin in the Woods and War for the Planet of the Apes were all filmed in Coquihalla Canyon.

The location is easily recognizable when watching First Blood where Sylvester Stallone hangs off the cliff while a helicopter tries to snipe him down.

As of May 2015, the tunnels have reopened after having been closed for over a year due to rockfall concerns.

Dewdney Peak

Dewdney Peak, also known unofficially as Hatzic Mountain, is the southwesternmost summit of the Douglas Ranges in the Lower Mainland of southern British Columbia, Canada. Dewdney Peak is located east of Hatzic Prairie and north of Dewdney, British Columbia, from whence it got its name.

Edge Peak

Edge Peak is a summit in the Golden Ears Group, located in Golden Ears Provincial Park north of Maple Ridge, British Columbia. The peak is not named for its shape but rather for Sam Edge who climbed it in 1876

. Other mountains in this area include Golden Ears and Blanshard Peak.

Indian Arm Provincial Park

Indian Arm Provincial Park is a provincial park in British Columbia, Canada. It is located on the western and eastern shores of Indian Arm, a glacial fjord extending north from Burrard Inlet near the city of Vancouver. The park also surrounds most of the land near Buntzen Lake, a reservoir managed by BC Hydro.

Mount Crickmer

Mount Crickmer is one of the southernmost summits of the Garibaldi Ranges of the Coast Mountains, overlooking the Central Fraser Valley in the Lower Mainland of British Columbia, Canada. Forming a rocky knoll at the northern end of a relatively flat-topped southeast-northwest axis ridge named Blue Mountain, which divides the basin of Alouette Lake, which lies immediately below it to the west, and the valley of the Stave River; Stave Lake is immediately at its eastern foot. A northerly ridge towards Mount Robie Reid, the next summit northwards, forms a col at Florence and Morgan Lakes low enough to give Crickmer a considerable prominence of 1049m. Beneath that col there is a diversion tunnel feeding the waters of Alouette Lake to the Alouette Powerhouse on Stave Lake.

Crickmer is the highest point in the District of Mission and was named on April 1, 1957 for the Reverend William Burton Crickmer, the first rector of the Church of St. John the Divine, at Derby (Old Fort Langley) in 1859.

Mount Judge Howay

Mount Judge Howay, originally the Snow Peaks (a term which included Mount Robie Reid), is a distinctive twin summit located 10 km (6 mi) from the Central Fraser Valley and, close up, the north end of Stave Lake. Being one of the highest peaks in the region, it is visible from many of the peaks around Vancouver, British Columbia. It is on the eastern side of Golden Ears Provincial Park.

Mount Robie Reid

Mount Robie Reid 2,095 m (6,873 ft) is a mountain in the southern end of the Garibaldi Ranges overlooking the Lower Mainland region of British Columbia, Canada. It lies to the north of Mission, British Columbia, Canada and on the west side of the upper end of Stave Lake, and to the northeast of the group of summits known as the Golden Ears. It has a prominence of 1,245 m (4,085 ft) relative to the lowest col between the valleys of Tingle and Osprey Creeks (Osprey Creek is tributary to the Pitt River drainage).

Together with Mount Judge Howay, which lies northeast across the deep valley of Tingle Creek, it was known as one of the Snow Peaks, and until its renaming in 1944 was referred to by old-timers as Old Baldy. Its name commemorates Robie Lewis Reid, a noted historian and educator whose colleague Frederic W. Howay is commemorated by Mount Judge Howay. Although relatively low, views of it dominate the mountain skyline from western Abbotsford and is also visible from Maple Ridge, North Surrey and New Westminster-Coquitlam, though from most of Mission it is invisible due to intervening smaller mountains and hill country.

Nicomen Mountain

Nicomen Mountain, 1,221 m (4,006 ft), is the southernmost major summit of the Douglas Ranges in the Lower Mainland region of southern British Columbia. It is located to the north of Nicomen Island and the communities of Deroche and Lake Errock. A local area Last Spike ceremony was held in 1884 on the Andrew Onderdonk Contract of the Canadian Pacific Railway; Nicomen was the scene of meeting of the two construction crews, one from Hope and one from Port Moody, of the ninety mile stretch through the lower Fraser Valley. The railway has used the mountain extensively for quarrying for gravel ballasting up to the present. Logging and farming continue in the area, though the mountain is still mostly forested.

Sasquatch Provincial Park

Sasquatch Provincial Park is a provincial park in Kent, British Columbia, Canada.

Skagit Valley Provincial Park

Skagit Valley Provincial Park is a provincial park in British Columbia, Canada, centred on the Skagit River and its tributaries. The park borders E. C. Manning Provincial Park in Canada and Ross Lake National Recreation Area and North Cascades National Park in the United States. It includes part of Ross Lake, a reservoir formed by a hydroelectric dam in Whatcom County, Washington.
