Thunder Bay is a city in and the seat of Thunder Bay District, Ontario, Canada. It is the most populous municipality in Northwestern Ontario and the second most populous (after Greater Sudbury) municipality in Northern Ontario; its population is 108,843 according to the 2021 Canadian Census. Located on Lake Superior, the census metropolitan area of Thunder Bay has a population of 123,258 and consists of the city of Thunder Bay, the municipalities of Oliver Paipoonge and Neebing, the townships of Shuniah, Conmee, O'Connor, and Gillies, and the Fort William First Nation.
European settlement in the region began in the late 17th century with a French fur trading outpost on the banks of the Kaministiquia River.  It grew into an important transportation hub with its port forming an important link in the shipping of grain and other products from western Canada, through the Great Lakes and the Saint Lawrence Seaway, to the east coast. Forestry and manufacturing played important roles in the city's economy. They have declined in recent years, but have been replaced by a "knowledge economy" based on medical research and education. Thunder Bay is the site of the Thunder Bay Regional Health Research Institute.
On 1 January 1970, the City of Thunder Bay was formed through the merger of the cities of Fort William, Port Arthur, and the geographic townships of Neebing and McIntyre. The city takes this name from the immense Thunder Bay at the head of Lake Superior, known on 18th-century French maps as Baie du Tonnerre (Bay of Thunder).  The city is often referred to as the "Lakehead", or "Canadian Lakehead", because of its location at the end of Great Lakes navigation on the Canadian side of the border. 
Various Anishinaabe peoples such as the Ojibwa are indigenous to the Thunder Bay Area.  European settlement at Thunder Bay began with two French fur trading posts (in 1683 and 1717) which were subsequently abandoned (see Fort William, Ontario). In 1803, the Montreal-based North West Company established Fort William as its mid-continent entrepôt . The fort thrived until 1821 when the North West Company merged with the Hudson's Bay Company, and Fort William was no longer needed.[ citation needed ]
By the 1850s, the Province of Canada began to take an interest in its western extremity. Discovery of copper in the Keweenaw Peninsula of Michigan had prompted a national demand for mining locations on the Canadian shores of Lake Superior. In 1849, French-speaking Jesuits established the Mission de l'Immaculée-Conception (Mission of the Immaculate Conception) on the Kaministiquia to evangelize the Ojibwe. The Province of Canada negotiated the Robinson Treaty in 1850 with the Ojibwa of Lake Superior. As a result, an Indian reserve was set aside for them south of the Kaministiquia River. In 1859–60, the Department of Crown Lands surveyed two townships (Neebing and Paipoonge) and the Town Plot of Fort William for European-Canadian settlement.[ citation needed ]
Another settlement developed a few miles to the north of Fort William after construction by the federal Department of Public Works of a road connecting Lake Superior with the Red River Colony. The work was directed by Simon James Dawson (see Port Arthur, Ontario). This public works depot or construction headquarters acquired its first name in May 1870 when Colonel Garnet Wolseley named it Prince Arthur's Landing. It was renamed Port Arthur by the Canadian Pacific Railway (CPR) in May 1883. 
The arrival of the CPR in 1875 sparked a long rivalry between the towns, which did not end until their amalgamation in 1970. Until the 1880s, Port Arthur was a much larger community. The CPR, in collaboration with the Hudson's Bay Company, preferred east Fort William, located on the lower Kaministiquia River where the fur trade posts were. Provoked by a prolonged tax dispute with Port Arthur and its seizure of a locomotive in 1889, the CPR relocated all its employees and facilities to Fort William. The collapse of silver mining after 1890 undermined the economy of Port Arthur. It had an economic depression, while Fort William thrived.
In the era of Sir Wilfrid Laurier, Thunder Bay began a period of extraordinary growth, based on improved access to markets via the transcontinental railway and development of the western wheat boom. The CPR double-tracked its Winnipeg–Thunder Bay line. The Canadian Northern Railway established facilities at Port Arthur. The Grand Trunk Pacific Railway began construction of its facilities at the Fort William Mission in 1905, and the federal government began construction of the National Transcontinental Railway. Grain elevator construction boomed as the volume of grain shipped to Europe increased. Both cities incurred debt to grant bonuses to manufacturing industries.
Thunder Bay was the first city in the world to enact daylight saving time, on 1 July 1908.  
By 1914, the twin cities had modern infrastructures (sewers, potable water supply, street lighting, electric light, etc.) Both Fort William and Port Arthur were proponents of municipal ownership. As early as 1892, Port Arthur built Canada's first municipally-owned electric street railway. Both cities spurned Bell Telephone Company of Canada to establish their own municipally-owned telephone systems in 1902.
The boom came to an end in 1913–1914, aggravated by the outbreak of the First World War. A war-time economy emerged with the making of munitions and shipbuilding. Men from the cities joined the 52nd, 94th, and 141st Battalions of the Canadian Expeditionary Force.
Railway employment was hurt when the federal government took over the National Transcontinental Railway and Lake Superior Division from the Grand Trunk in 1915, and the Canadian Northern Railway in 1918. These were amalgamated with other government-owned railways in 1923 to form the Canadian National Railways. The CNR closed many of the Canadian Northern Railway facilities in Port Arthur. It opened the Neebing yards in Neebing Township in 1922. By 1929, the population of the two cities had recovered to pre-war levels.
The forest products industry has played an important role in the Thunder Bay economy from the 1870s. In the 1880s, Herman Finger established the Pigeon River Lumber Company in the area, and also built the Gunflint and Lake Superior Railroad, but he dissolved the lumber company and moved his operations to The Pas by 1919.  Logs and lumber were shipped primarily to the United States. In 1917, the first pulp and paper mill was established in Port Arthur. It was followed by a mill at Fort William, in 1920. Eventually, there were four mills operating.
Manufacturing resumed in 1937 when the Canada Car and Foundry Company plant (opened for the manufacture of naval ships and railcars during the late World War I) re-opened to build British aircraft. Now run by Alstom, the plant has remained a mainstay of the post-war economy. It has produced forestry equipment and transportation equipment for urban transit systems, such as the Toronto Transit Commission and GO Transit.
On 1 January 1970, the City of Thunder Bay was formed through the merger of the cities of Fort William, Port Arthur, and the geographic townships of Neebing and McIntyre.  Its name was the result of a referendum held previously on 23 June 1969, to determine the new name of the amalgamated Fort William and Port Arthur. Officials debated over the names to be put on the ballot, taking suggestions from residents including "Lakehead" and "The Lakehead". Because the vote split between the two similar names, "Thunder Bay" prevailed with a narrow plurality. The final tally was "Thunder Bay" with 15,870, "Lakehead" with 15,302, and "The Lakehead" with 8,377. 
There was more controversy over the selection of a name for the amalgamated city than over whether to amalgamate. A vocal minority of the population preferred "The Lakehead".  There was much discussion about other cities in the world that use a definite article in their names. The area was often referred to as "The Lakehead" before and after amalgamation based on its geographic location. It was seen as the "head" of shipping on the Great Lakes and the "rail head".
The expansion of highways, beginning with the Trans-Canada Highway and culminating with the opening of Highway 17 (linking Sault Ste Marie to Thunder Bay in 1960), has significantly diminished railway and shipping activity since the 1970s and 80s. Shipping on the Saint Lawrence Seaway was superseded by trucking on highways. Grain shipping on the Great Lakes to the East has declined substantially in favour of transport to Pacific Coast ports. As a result, many grain elevators have been closed and demolished. The Kaministiquia River was abandoned by industry and shipping. 
Thunder Bay has become the regional services centre for Northwestern Ontario with most provincial departments represented. Lakehead University, established through the lobbying of local businesspeople and professionals, has proven to be a major asset. Another upper level institution is Confederation College.
The city has an area of 328.48 square kilometres (126.83 sq mi), which includes the former cities of Fort William and Port Arthur, as well as the former townships of Neebing and McIntyre. The city reflects the settlement patterns of the 19th century and sprawls. Anchoring the west end of the city, the Fort William Town Plot, surveyed in 1859–60, was named West Fort William (or Westfort) in 1888 by the CPR. The land adjoining the lower Kaministiquia River became the residential and central business district of the town and city of Fort William. A large uninhabited area adjoining the Neebing and McIntyre rivers, which became known as Intercity, separated Fort William from the residential and central business district of Port Arthur. At the extreme east of the city, a part of McIntyre Township was annexed to the town of Port Arthur in 1892, forming what later became known as the Current River area.[ citation needed ]
The former Port Arthur section is more typical of the Canadian Shield, with gently sloping hills and very thin soil lying on top of bedrock with many bare outcrops. Thunder Bay, which gives the city its name, is about 22.5 kilometres (14.0 mi) from the Port Arthur downtown to Thunder Cape at the tip of the Sleeping Giant. The former Fort William section occupies flat alluvial land along the Kaministiquia River. In the river delta are two large islands: Mission Island and McKellar Island. Since 1970, the central business districts of Fort William and Port Arthur have suffered a serious decline. Business and government relocated to new developments in the Intercity area. There has also been substantial residential growth in adjacent areas of the former Neebing and McIntyre townships.[ citation needed ]
Thunder Bay is composed of two formerly separate cities: Port Arthur and Fort William. Both still retain much of their distinct civic identities, reinforced by the buffering effect of the Intercity area between them. Port Arthur and Fort William each have their own central business districts and suburban areas. Some of the more well-known neighbourhoods include the Bay and Algoma area, which has a large northern European population centred around the Finnish Labour Temple and the Italian Cultural Centre; Simpson-Ogden and the East End, two of the oldest neighbourhoods in Fort William located north of Downtown Fort William; Intercity, a large business district located between Fort William and Port Arthur; Current River, the northernmost neighbourhood of Port Arthur; and Westfort, the oldest settlement in Thunder Bay. Within city limits are some small rural communities, such as Vickers Heights and North McIntyre, which were located in the former townships of Neebing and McIntyre, respectively.

|Climate chart (explanation)|
The Thunder Bay area experiences a warm-summer humid continental climate (Köppen: Dfb) and a continental subarctic (Dfc) influence in northeastern areas of the city (including that affected by Lake Superior), but not necessarily falling in this zone.   This results in cooler summer temperatures and warmer winter temperatures for an area extending inland as far as 16 km. The average daily temperatures range from 17.7 °C (63.9 °F) in July to −14.3 °C (6.3 °F) in January. The average daily high in July is 24.3 °C (75.7 °F) and the average daily high in January is −8.0 °C (17.6 °F).  On 10 January 1982, the local temperature in Thunder Bay dropped to −36.3 °C (−33.3 °F), with a wind speed of 54 km (34 mi) per hour for a wind chill temperature that dipped to −58 °C (−72.4 °F).   As a result, it holds Ontario's record for coldest day with wind chill.  The highest temperature ever recorded in Thunder Bay was 40.3 °C (104.5 °F) on 7 August 1983.  The coldest temperature ever recorded was −43.2 °C (−45.8 °F) on 31 January 1996.  Relatively recently, however, all-time records for both the latest first freeze and the longest growing season were set on October 17, 2021; the previous record of October 8, 2016 was beaten by 9 days, and the previous record for the longest growing season of 139 days (also set in 2016) was beaten by a day. 
The city is quite sunny, with an average of 2,121 hours of bright sunshine each year, ranging from 268.1 hours in July to 86.2 hours in November.  Winters are comparatively dry with the snowfall being very limited and temperatures much colder than in Houghton, Michigan, on the U.S. side of the lake, where the climate is marked by heavy lake-effect snow. Thunder Bay has more of a continental climate in comparison.

In the 2021 Census of Population conducted by Statistics Canada, Thunder Bay had a population of 108,843 living in 48,405 of its 50,995 total private dwellings, a change of 0.9% from its 2016 population of 107,909. With a land area of 327.77 km2 (126.55 sq mi), it had a population density of 332.1/km2 (860.1/sq mi) in 2021. 
At the census metropolitan area (CMA) level in the 2021 census, the Thunder Bay CMA had a population of 123,258 living in 54,212 of its 57,877 total private dwellings, a change of 1.3% from its 2016 population of 121,621. With a land area of 2,550.79 km2 (984.87 sq mi), it had a population density of 48.3/km2 (125.2/sq mi) in 2021. 
According to the 2016 Census, 48.8% of Thunder Bay's residents were male and 51.2% were female. Residents 19 years of age or younger accounted for approximately 19.9% of the population. People aged by 20 and 39 years accounted for 25.0%, while those between 40 and 64 made up 35.1% of the population.

From 2012 to 2014, and again from 2016 to 2019, Thunder Bay had the highest per-capita rate of homicide among Canadian cities.  Winnipeg had previously held this distinction between 2007 and 2011.   In 2014, the per-capita rate of homicides in Thunder Bay was more than double the 2012 rate, and was over 2.5 times higher than the city with the next highest rate.  However, between 2014 and 2015, the crime rate decreased by 6%. This was the second highest decrease in any major Canadian city, behind only Moncton, New Brunswick. 
|Labour force |
|As of: Census 2016|
As the largest city in Northwestern Ontario, Thunder Bay is the region's commercial, administrative and medical centre. Many of the city's largest single employers are in the public sector. The City of Thunder Bay, the Thunder Bay Regional Health Sciences Centre, the Lakehead District School Board and the Government of Ontario each employ over 1,500 people.  Resolute Forest Products is the largest private employer, employing over 1,500 people. 
Bombardier Transportation operates a 553,000 square feet (51,400 m2) plant in Thunder Bay which manufactures mass transit vehicles and equipment, employing approximately 800 people.  The plant was built by Canadian Car and Foundry to build railway box cars in 1912, began building passenger railcar and transit cars from 1963 onwards   Bombardier acquired the facility from UTDC in 1992, which had acquired it from Cancar in 1984.

Lack of innovation by traditional industries, such as forest products, combined with high labour costs have reduced the industrial base of Thunder Bay by close to 60%. The grain trade has declined because of the loss of grain transportation subsidies and the loss of European markets. The gradual transition from shipping by train and boat to shipping by truck, and the Canada–United States Free Trade Agreement have ended Thunder Bay's privileged position as a linchpin in Canadian east–west freight-handling trade. As a result, the city has lost its traditional raison d'être as a break-bulk point. However, in recent years shipments through the port of Thunder Bay have stabilized, and it remains an important part of the Saint Lawrence Seaway. 
In an effort to rejuvenate its economy, the city has been actively working to attract quaternary or "knowledge-based" industries, primarily in the fields of molecular medicine and genomics.   The city is home to the western campus of the Northern Ontario School of Medicine, the first medical school to open in Canada in a generation.  The city also has a law school. 
The city is governed by a mayor and twelve councillors. The mayor and five of the councillors are elected at large by the whole city. Seven councillors are elected for the seven wards: Current River Ward, McIntyre Ward, McKellar Ward, Neebing Ward, Northwood Ward, Red River Ward, and Westfort Ward. 
Thunder Bay is represented in the Canadian Parliament by Marcus Powlowski, and Patty Hajdu, both members of the Liberal Party of Canada, and in the Ontario Legislature by Lise Vaugeois of the Ontario New Democratic Party and Kevin Holland of the Ontario Progressive Conservative Party.
A large formation of mesas on the Sibley Peninsula in Lake Superior which resembles a reclining giant has become a symbol of the city. Sibley peninsula partially encloses the waters of Thunder Bay, and dominates the view of the lake from the northern section of the city (formerly Port Arthur). The Sleeping Giant also figures on the city's coat of arms and the city flag.
The coat of arms of Thunder Bay, Ontario, is a combination of the coats of arms of both Port Arthur and Fort William, with a unifying symbol—the Sleeping Giant—at the base of the arms. 
The city logo depicts a stylized thunderbird, called Animikii, a statue of which is located at the city's Kaministiquia River Heritage Park.  The slogan, Superior by Nature, is a double play on words reflecting the city's natural setting on Lake Superior. 
Thunder Bay's flag was created in 1972, when mayor Saul Laskin wanted to promote the city by having a distinctive flag. The city held a contest, which Cliff Redden won. The flag has a 1:2 ratio and depicts a golden sky from the rising sun behind the Sleeping Giant, which sits in the blue waters of Lake Superior. The sun is represented by a red maple leaf, a symbol of Canada. Green and gold are Thunder Bay's city colours. 
The city of Thunder Bay was declared a "Cultural Capital of Canada" in 2003.  Throughout the city are cultural centres representing the diverse population, such as the Finnish Labour Temple, Scandinavia House, the Italian Cultural Centre, the Polish Legion, and a wide variety of others.
The shag, a combination shower and stag held to celebrate the engagement of a couple,  and the Persian, a cinnamon bun pastry with pink icing, both originated in the city.  
Thunder Bay is served by the Thunder Bay Public Library, which has four branches.
Events in the city include Thunder Pride, an LGBTQ pride parade held since 2010, and the annual Canadian Lakehead Exhibition.
Thunder Bay is home to a variety of music and performance arts venues. The Thunder Bay Symphony Orchestra, founded in 1960, is the only professional orchestra between Winnipeg and Toronto and has 31 full-time and up to 30 extra musicians presenting a full range of classical music.  New Music North is vital to the contemporary classical music scene in the city by offering novel contemporary chamber music concerts.  The largest professional theatre is Magnus Theatre. Founded in 1971, it offers six stage plays each season and is located in the renovated Port Arthur Public School on Red River Road. The Thunder Bay Community Auditorium, which seats 1500, is the primary venue for various types of entertainment.
The Vox Popular Media Arts Festival, established in 2005, is an independent film festival that features local, national, and international films with the theme of "Films for the People." The festival is held in early October at 314 Bay Street in the historic Finnish Labour Temple.  Thunder Bay is also home to the North of Superior Film Association (NOSFA). Established in 1992, the NOSFA features monthly screenings of international and Canadian films at the Cumberland Cinema Centre, and organized the annual Northwest Film Fest film festival that attracts several thousand patrons.  Two of Thunder Bay's festivals were included in the 2018 list of the 100 best festival compiled by Festivals and Events Ontario: Teddy Bears Picnic and Live on the Waterfront, the former also being recognized as best promotional campaign and sponsor of the year. 
The Northwestern Ontario Writers Workshop (NOWW), founded in 1997, is the largest of several writing groups based in Thunder Bay. Its mission is "to encourage and promote the development of the writers and literature of Northwestern Ontario".  NOWW does this through a number of activities including regular workshops, monthly readings (summer excepted), an eWriter in Residence program, and other events designed to help and inspire writers in the region. NOWW also hosts an annual LitFest in May which includes an awards presentation to the winners of its international annual writing contest.  Past contest judges include a Who's Who of Canadian writers such as Heather O'Neill, Michael Christie, Jane Urquhart, and Liz Howard.
The Thunder Bay Art Gallery, which was founded in 1976, specializes in the works of First Nations artists, having a collection of national significance. The Thunder Bay Historical Museum Society, founded in 1908, presents local and travelling exhibitions and houses an impressive collection of artifacts, photographs, paintings, documents and maps in its archives. The City of Thunder bay also houses the Northwestern Ontario Sports Hall of Fame, and the Thunder Bay Military Museum (housed within the O'Kelley Armoury on Park Street).
Thunder Bay has two recognized Federal Heritage buildings on the Register of the Government of Canada Heritage Buildings:
Both are part of HMCS Griffin.
Thunder Bay has many places of worship supported by people of a variety of faiths, reflecting the cultural diversity of the population.  A sample:
Thunder Bay's main tourist attraction is Fort William Historical Park, a reconstruction of the North West Company's Fort William fur trade post as it was in 1815, which attracts 100,000 visitors annually.  The marina in downtown Port Arthur, an area known as The Waterfront District, draws visitors for its panoramic view of the Sleeping Giant and the presence of various water craft. The marina, known as Prince Arthur's landing also includes recreational trails along the lake, playground, harbour cruises, helicopter tours, the Alexander Henry (a retired Canadian Coast Guard icebreaker), splash pad (summer), skating rink (winter), and art gallery, gift shop, numerous restaurants, and a newly opened Delta Hotel and conference centre. There are several small surface amethyst mines in the area, some of which allow visitors to search for their own crystals.  A 2.74 m (9 ft) statue of Terry Fox is situated at the Terry Fox Memorial and Lookout on the outskirts of the city near the place where he was forced to abandon his run.
