Etymology
In Halq'eméylem, the language of the Stó:lō communities around Chilliwack and Sardis, Tcil'Qe'uk means "valley of many streams". It also lends its name to the Chilliwack River, and group of aboriginal people, the Ts'elxwéyeqw (also spelled Ts'elxwíqw or Sts'elxwíqw).Chilliwack Museum and Archives The spelling of Chilliwack is sometimes a matter of confusion. Prior to the amalgamation of the City of Chilliwack and the Municipality of Chilliwhack, there were two different spellings. At the time of the amalgamation, the current spelling of the city's name was adopted. Anglicized spellings include "Chilliwhyeuk" and other versions closer to the original Halq'eméylem.
History
The archeological record shows evidence of Stó:lō people in the Fraser Valley, or S'ólh Téméxw, 10,000 years ago. Permanent structures in the Chilliwack area date from around 5,000 years ago. It is estimated that at the time of the first contact with Europeans, there were as many as 40,000 people living within Stó:lō territory.
19th century
In the mid-nineteenth century, thousands of gold miners transited the area en route to the goldfields of the upper Fraser River. By the mid-1860s, settlers had established farms around Codville's Landing, Miller's Landing, Minto Landing, Sumas Landing, and Chilliwack Landing along the Fraser River.
On April 26, 1873, the "Corporation of the Township of Chilliwhack" (note the variant spelling) became the third municipality incorporated by the Province of British Columbia. The town centre at the time was concentrated at Chilliwack Landing along the Fraser River. Steamboats were the main mode of transportation, carrying goods and passengers between Chilliwhack and New Westminster. After the construction of the Canadian Pacific Railway (CPR) in 1885, many residents began to cross the Fraser River at Minto Landing to ride the train from Harrison Mills.
In 1881, with little room for expansion and the threat of floods constantly looming, the town centre was moved south to "Five Corners" at the junction of the New Westminster-Yale Wagon Road, Wellington Avenue and Young Road. This subdivision was initially named "Centreville", but later was renamed "Chilliwack", as it was more commonly referred to by locals in 1887. The area would experience catastrophic flooding in 1894, 1935, 1948 and 2021.
On April 20, 1891, Richard Plunkett Cooke, George de Wolf, and Walter E. Graveley established the Chilliwhack Railway Company.
Early 20th century
On February 20, 1908, the area that was then known as Chilliwack, i.e., the subdivision within the greater Chilliwhack Township, was proclaimed as the City of Chilliwack by letters patent issued by the provincial government under the Chilliwack City Incorporation Act. The City of Chilliwack and the Township of Chilliwhack co-existed as separately administered municipalities until 1980.
On October 4, 1910, the British Columbia Electric Railway began operating regularly scheduled passenger service on the New Westminster–Chilliwack Interurban Line.
In 1941, Camp Chilliwack was established following Canada's entry into the Second World War in 1939. After the outbreak of the Pacific War, the camp was expanded to garrison Canadian Army units for the defence of Canada's West Coast. It continued to be used as a permanent training facility and army garrison during the Cold War. Following the unification of the Canadian Armed Forces in 1968, the base was renamed Canadian Forces Base Chilliwack (CFB Chilliwack). The base housed the following units:
Late 20th century
On January 1, 1980, the Township of Chilliwhack and the City of Chilliwack were amalgamated to form a single municipality styled the District of Chilliwack, following the passage of referendae in both municipalities. On July 16, 1999, the District of Chilliwack, once again, was renamed the City of Chilliwack. To the present day, locals idiosyncratically use the same name to refer to the city as a whole, and to the old city centre. It is also the name of the greater metropolitan area encompassing adjacent sovereign indigenous nations, municipalities, and unincorporated areas.
In 1997, following the end of the Cold War a few years earlier, CFB Chilliwack closed. Its training facilities were converted into the Canada Education Park, a campus for multiple institutions, including the Justice Institute of British Columbia, the Royal Canadian Mounted Police, the University of the Fraser Valley, and the Western Area Training Centre (WATC). Today it also houses supply depots for the 39 Canadian Brigade Group of the Canadian Army and the Royal Canadian Army Cadets. The old quartermaster warehouse became the Canadian Military Education Centre Museum.
Geography
Chilliwack is located in the Upper Fraser Valley, east of Vancouver on the Trans-Canada Highway. The city is bounded on the north by the Fraser River, and on the south by the Canada-United States border.
Chilliwack is surrounded by tall mountain peaks, such as Mount Cheam and Slesse Mountain, and large rivers (the Fraser and Vedder).
Geology The Chilliwack Batholith forms much of the North Cascades in southwestern British Columbia, Canada and the U.S. state of Washington. The geological structure is primarily named after the City of Chilliwack, where it is the most notable geological feature.
The Chilliwack Batholith is part of the Pemberton Volcanic Belt and is the largest mass of exposed intrusive rock in the Cascade Volcanic Arc. The age of the Chilliwack batholith ranges from 26 to 29 million years old.
In 2013, Maclean's reported that, with an average annual temperature of , Chilliwack is the warmest city in Canada.
Climate The climate is typical oceanic (Köppen: Cfb) but with some influence of the land mass being some distance from the sea, similar to Orléans, France (although the former has a precipitation more than twice as long and with a tendency towards the Mediterranean pattern). Chilliwack's mild climate with limited extremes provides excellent growing conditions for a wide variety of crops and agricultural products. In fact, when averaged from 1981 to 2010, Chilliwack had one of the warmest mean temperatures for any city in Canada.
The highest temperature recorded within the city of Chilliwack is on June 28, 2021, which was set during the 2021 Western North America Heat wave, beating the old mark of recorded on July 21, 2006. The lowest recorded temperature was on December 27, 1968. Precipitation falls mostly as rain, with snow limited to the surrounding mountains, except for two or three weeks per year generally in December or January when arctic outflow occurs. In 2013, Maclean's wrongly reported that with an average annual temperature of , Chilliwack is the warmest city in Canada. The actual warmest city in Canada is Victoria, with an average annual temperature of . Chilliwack enjoys some of the warmest average high temperatures in Canada, with 15.5 °C (59.9 °F) being the yearly average high.
Chilliwack receives nearly the same number of days of precipitation (184.6 days at greater than 0.2 mm) as comparable local communities near Vancouver such as Maple Ridge (185.8 days) and the City of Mission (186.0 days) (Environment Canada Statistics). Summers in Chilliwack are usually sunny and warm, with long days (light out until well after 10 pm in June with dusk that lasts for hours) and with occasional stretches of heat where temperatures rise above .
Due to its location at the eastern end of the Fraser Valley, there has been some debate about preserving Chilliwack's air quality. However, the 2011 World Health Organization's study of air quality shows that Chilliwack enjoys air quality among the best in the world. For PM10 (10 μm) size particulates, Canada averaged third best in the world (along with Australia) at an average of 13 micrograms per cubic metre. The City of Chilliwack and the Greater Vancouver Regional District were tied at a low 8.0 MPCM. For smaller particulate of 2.5 μm size (PM2.5), "the City of Chilliwack averaged 4.9 micrograms per cubic metre. Vancouver also had 4.9, Calgary had 5.6, Winnipeg had 5.6, Toronto had 7.9, Montreal had 11.2 and Sarnia had 12.7."
