Timeline of Calgary history

Pre-Contact and Early European Encounters

Archaeological evidence indicates human presence in the Calgary region for at least 12,000 years, with the area's abundant game and fish resources attracting nomadic groups. Over millennia, the land was home to several dominant cultures, with the Blackfoot people arriving approximately 2,000 years ago from the Eastern Woodlands. The Sarcee people came to the area from the north around the early 1700s, followed by the Stoney people from Manitoba. Physical traces of these early inhabitants include spear points, campsites, bison kill sites, tipi rings, and storage pits dating back over 4,000 years. Religious and ceremonial sites featuring cairns, effigies, and medicine wheels have also been documented, and pictographs can be viewed on the Big Rock near Okotoks. The first recorded European to visit the area was the cartographer David Thompson, who spent the winter of 1787 with a band of Peigan travellers encamped along the Bow River.

Founding, Railway, and Early Growth (1870s-1890s)

The modern founding of Calgary is rooted in the westward expansion of Canada and the establishment of law and order. In 1870, the future site became part of Canada and the North-West Territories. John Glenn became the first documented European settler in the area in 1873. The establishment came in 1875 when the North-West Mounted Police built a post, initially called Fort Brisebois after officer Éphrem-A. Brisebois, to combat whisky trading and protect the fur trade. The I.G. Baker Company from Fort Benton, Montana, constructed the original fort and a log store. The name was changed to Fort Calgary by Colonel James Macleod in 1876. The signing of Treaty 7 in 1877 formally ceded the area's title to the Crown. The federal government began offering cattle ranching leases in Alberta in 1881, which spurred immigration. The settlement's fortunes were permanently altered with the arrival of the Canadian Pacific Railway in 1883, which prompted the relocation of the town's core across the Elbow River and spurred rapid growth. The CPR began selling lots around the new station, with corner lots priced at $450. Calgary was officially incorporated as a town in 1884, electing George Murdoch as its first mayor, and the Calgary Police Service was established the following year. The devastating Calgary Fire of 1886 led to a reconstruction largely in sandstone. The Calgary and District Agricultural Society held its first fair in 1886, attracting 500 of the town's 2,000 residents. Growth continued, leading to incorporation as The City of Calgary in 1894 within the North-West Territories.

Growth, Innovation, and Social Change (1900 to 1945)

The early 20th century saw Calgary expand in population, infrastructure, and civic influence. The city annexed communities like Parkdale in 1910 and surpassed 50,000 residents by 1913. A major cultural occasion, the Calgary Stampede, was first held in 1912. The city became a national leader in electoral reform, adopting a form of proportional representation for city councillors in 1917, which also saw the election of Calgary's first female councillor, Hannah Gale. This system remained in use for council elections until 1961, was used again in 1971, and was employed for the last time in that year. During this period, the mayor was elected using instant-runoff voting. The period was also marked by labour activism, including a general strike in 1919 as part of the Canadian Labour Revolt and the formation of the One Big Union in the city. The Glenmore Dam was constructed between 1932 and 1933 to secure the city's water supply. In 1932, the Co-operative Commonwealth Federation, the forerunner of the New Democratic Party, was founded at a meeting in Calgary. The city's military units were reorganized, with the 103rd Calgary Rifles created in 1910, becoming The Calgary Regiment in 1920, and The Calgary Highlanders splitting off as its own regiment in 1924. The Calgary Stampeders of the Canadian Football League began play in 1945, and the city's population passed 100,000 in 1946.

Post-War Boom and Modernization (1945 to 1988)

The post-war era changed Calgary into a major urban centre, driven largely by the oil and gas industry. Major construction projects reshaped the skyline, beginning with the Husky Tower, whose construction started in 1967 and it opened to the public on June 30, 1968. The innovative +15 enclosed pedestrian walkway system debuted downtown in 1970. The city's population exceeded 500,000 by 1978. Professional sports arrived with the relocation of the NHL's Atlanta Flames to become the Calgary Flames in 1980. The CTrain light rail transit system began operation in 1981, and the Suncor Energy Centre became the city's tallest building upon its completion in 1984. This period culminated in Calgary hosting the XV Olympic Winter Games in 1988. The following year, the Flames won the Stanley Cup, defeating the Montreal Canadiens on their home ice. Key infrastructure and cultural developments from this era include several specific events and constructions.

• 1947: Stampede Wrestling is established.
• 1955: Last provincial election where Calgary MLAs were elected through the single transferable vote system.
• 1971: Last civic election using single transferable voting for councillors and instant-runoff voting for mayor.
• 1988: Calgary hosts the 1988 Winter Olympics.
• 1989: Bankers Hall-East completed construction. The Flames win the Stanley Cup.
• 1992: Stephen Avenue is designated a National Historic Site of Canada.
• 1996: Canadian Pacific Railway moves its head office from Montreal to Calgary.
• 1997: Calgary hosts the World Police and Fire Games and drafts the Calgary Declaration on national unity.
• 1999: Hub Oil explosion occurs.
• 2000: Bankers Hall-West is completed.

The Contemporary City: Growth and Challenges (21st Century)

The 21st century has seen Calgary experience continued growth, economic cycles, and significant challenges. The city's population surpassed one million residents in 2007. The skyline continued to change, with The Bow surpassing the Suncor Energy Centre as the tallest building in 2010, a title later taken by Brookfield Place East in 2018. Eighth Avenue Place I was completed in 2011. The city faced a major natural disaster in 2013 when widespread flooding across southern Alberta forced the evacuation of approximately 75,000 Calgary residents. In 2018, a city-wide plebiscite resulted in the withdrawal of Calgary's bid to host the 2026 Winter Olympics. The global COVID-19 pandemic affected the city beginning in 2020. Culturally, the annual Historic Calgary Week festival, exploring local history through walks and talks, continues, with its 36th edition scheduled for July 24 to August 3, 2026, featuring over 75 events.

Military, Electoral, and Political History

Calgary has a distinct history in military organization, electoral systems, and political movements. The 103rd Calgary Rifles was created in 1910, later reorganized as The Calgary Regiment in 1920. In 1924, The Calgary Highlanders split from the Calgary Regiment to become its own distinct infantry unit. The Calgary Regiment was renamed The King's Own Calgary Regiment in 1948. The Mewata Armouries were constructed between 1915 and 1918. On the civic front, Calgary was a pioneer in electoral reform in Canada. It became the first Canadian city to use a form of proportional representation, specifically the single transferable vote, to elect its city councillors starting in 1917. This system remained in place for council elections until 1961, was briefly reinstated in 1971, and was used for the last time in that year. During this period, the mayor was elected using instant-runoff voting. The system was also used provincially. Calgary MLAs were elected using STV in a city-wide district from the 1926 Alberta election until 1955. Politically, the city elected two Labour Party candidates, William Irvine and Joseph Tweed Shaw, to the House of Commons in 1921. The Co-operative Commonwealth Federation party was formed at a meeting in Calgary in 1932. No CCF or NDP MLAs were elected in Calgary under the first-past-the-post system after 1955 until 1986.

Cultural Institutions, Events, and Disasters

Calgary's cultural scene is anchored by long-standing institutions and popular annual events. The Calgary Stampede, first held in 1912 and becoming an annual event in 1923, is the city's most famous celebration, rooted in its ranching heritage. It originated from earlier agricultural fairs run by the Calgary and District Agricultural Society and the Western Pacific Exhibition Company. Historic Calgary Week, an 11-day festival of walks, tours, and presentations organized by the Historical Society of Alberta, has been running for over three decades. The city's professional sports teams, the Calgary Flames and Calgary Stampeders, are central to its community identity. Other significant cultural fixtures include Stampede Wrestling, founded in 1947. The city has also faced disasters and civil unrest. The Calgary Fire of 1886 destroyed much of the early wooden town. The Great Depression saw periods of civil strife, with battles between police and unemployed men. The Hub Oil explosion occurred in 1999. The flood of 2013 was a major disaster, leading to large-scale evacuations.

Annexations and Urban Expansion

The physical growth of Calgary has been achieved through a series of annexations of surrounding localities, expanding its municipal boundaries over time. The process began early in the city's history, with the annexation of the community of Parkdale recorded in 1910. This pattern of absorbing neighbouring areas continued throughout the 20th century as the city's population and economic needs grew. Through these various annexations, numerous former independent settlements and districts are now within Calgary's city limits. This expansion was necessary to accommodate residential development, industrial areas, and infrastructure like the Glenmore Dam, which was built on annexed land between 1932 and 1933. The annexations reflect Calgary's evolution from a compact railway town to a sprawling metropolitan area that surpassed one million residents in 2007, requiring ever-greater land for housing, services, and transportation networks like the CTrain system.
