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 They have declined in recent years, but have been replaced by a "knowledge economy" based on medical research and education.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.

The city takes its 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.


Before 1900

European settlement at Thunder Bay began with two French fur trading posts (1683, 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.

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.

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 the amalgamation of 1970. Until the 1880s, Port Arthur was a much larger and dynamic 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.

20th century

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.

By 1914, the twin cities had modern infrastructures (sewers, safe 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 1913–14, 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. 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 during late World War I to produce naval ships and railcars) re-opened to build aircraft for the British. Now run by Bombardier Transportation, 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". Predictably, the vote split between the two, and "Thunder Bay" was the victor. 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 majority of the population preferred the "Lakehead". There was much discussion over whether there was any other city in the world that uses the word "The" in its name, which there is, as The Pas, Manitoba has "The" in its name, for example. 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 businessmen and professionals, has proved to be a major asset. Another upper level institution is Confederation College. The same businessmen and professionals who helped attract the university and college were the driving force(s) behind the political amalgamation of Fort William and Port Arthur in 1970.

The city has an area of 328.48 square kilometres, 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.

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.


The Thunder Bay area experiences a humid continental climate (Köppen climate classification Dfb) that is influenced by Lake Superior, with especially noticeable effects in the city's north end. 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) 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.

The city is quite sunny, with an average of 2121 hours of bright sunshine each year, ranging from 268.1 hours in July to 86.2 hours in November, sunnier than any city in Canada located to the east of it. 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.

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 has its 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.

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.


Thunder Bay has 38 elementary schools, three middle schools, eight secondary schools, two private schools, and an adult education facility. The city also has several other private for-profit colleges and tutoring programmes. Post-secondary institutions in Thunder Bay include Confederation College and Lakehead University.

The Lakehead District School Board is the largest school board in the city, with 22 elementary schools, 3 high schools and a centre for adult studies. The Thunder Bay Catholic District School Board is the second largest, with 16 elementary schools, three middle schools and two high schools. Conseil scolaire de district catholique des Aurores boréales operates one elementary and one high school in Thunder Bay, and an additional six schools throughout the Thunder Bay District.



Thunder Bay receives air, rail and shipping traffic due to its prime location along major continental transportation routes. The municipally owned Thunder Bay Transit operates 17 routes across the city's urban area. The city is served by the Thunder Bay International Airport, the fourth busiest airport in Ontario by aircraft movements. The main highway through the city is Highway 11/17, a four-lane highway designated as the Thunder Bay Expressway.

The city is an important railway hub, served by both the Canadian National and Canadian Pacific Railway. Passenger rail service to Thunder Bay ended on 15 January 1990, when Via Rail rerouted the Canadian to the north.


Thunder Bay has been a port since the days of the North West Company, which maintained a schooner on Lake Superior. The Port of Thunder Bay is the largest outbound port on the St. Lawrence Seaway System, and the sixth-largest port in Canada. The Thunder Bay Port Authority manages Keefer Terminal, built on a 320,000 square metre site on Lake Superior.
