Sault Ste. Marie, Ontario
Sault Ste. Marie is a city in Northern Ontario, Canada, situated on the north shore of the St. Mary's River directly across from its American twin city of the same name in Michigan. With a population of 72,051 as of the 2021 census, it is the third most populous city in Northern Ontario. The city serves as a regional hub for manufacturing, particularly steel production, as well as tourism and health services. Its location at the rapids, or 'Sault', of the St. Mary's River has defined its history as a crucial meeting point for Indigenous peoples, a centre for the fur trade, and a modern international border crossing.
History and Indigenous Roots
The area now known as Sault Ste. Marie has been inhabited for over 500 years by the Ojibwe, who call it Baawitigong, meaning 'place of the rapids'. This location at the St. Mary's River rapids was a vital stopping point and strategic meeting place for Algonquin peoples, with a permanent settlement of 150 to 200 people that swelled to thousands during the annual whitefish harvest. The first recorded European to see the rapids was French explorer Étienne Brûlé in 1621, and the French initially named the rapids Sault de Gaston in honour of the brother of King Louis XIII. French Jesuit missionaries established a mission on the river's south bank in 1668, renaming the area Sault Sainte-Marie, which makes the Michigan settlement one of the oldest French settlements in North America. The name originates from the French 'Saults de Sainte-Marie', referencing the Saint Mary's falls or rapids, with 'sault' being an archaic term for a cataract that survives almost exclusively in 17th-century place names.
For over a century, Sault Ste. Marie was a cosmopolitan crossroads of the continental fur trade, forming a key juncture on the 5,000-kilometre route from Lake Superior to Montreal. A mixed population of Europeans, First Nations, and Métis grew up around the North West Company fur trading post established around 1790. Prominent figures like Scots-British trader John Johnston and his Ojibwe wife, Ozhaguscodaywayquay, were central to community life in the late 1700s, and their daughter Jane Johnston married American ethnographer Henry Rowe Schoolcraft. This fluid cross-border environment shifted during the War of 1812 when an American force destroyed the North West Company depot on the north shore in July 1814. After the war, the new international boundary restricted movement and trade as the US closed its territory to British Canadian traders. The community was incorporated as a village in 1871 with a population of almost 880 and became a town in 1887.
Industrial Development and Railway History
The city's modern industrial character began in the early 1900s, led by industrialists like Francis Clergue, transforming it into a regional centre for resource development and manufacturing. A crucial moment was the completion of the Sault Ste. Marie Canal in 1895, built to ensure Canadian control over the vital water passage after the United States refused passage to the steamer Chicora, carrying Colonel Garnet Wolseley, through the American locks in 1870. The city's connection to the national railway network was contested and shaped by both commercial and national security interests. While American railway magnate James J. Hill advocated for a route through Sault Ste. Marie to link with his US lines, fears of American expansionism and the memory of the slow Wolseley expedition during the Red River Rebellion favoured an all-Canadian rail route for military transportation. The Canadian Pacific Railway ultimately built its main transcontinental line through the interior from Sudbury Junction, bypassing the city and fuelling the explosive mining growth in the Sudbury Basin instead.
The original CPR line to Sault Ste. Marie, known as the Algoma Branch, lay dormant for years before being reactivated and completed in 1888, connecting to the US via the joint Sault Ste. Marie International Railroad Bridge. Competing railway projects, like the Northern, North-Western, and Sault Ste. Marie Railway, collapsed during this period. The city's economy initially stagnated with the decline of the fur trade but was revitalized by heavy industry, particularly steel manufacturing.
20th Century and Modern Governance
During the Second World War, Sault Ste. Marie became a point of strategic military concern due to its shipping channels and locks. Fears of a potential air attack by Nazi German aircraft flying over the Arctic from occupied Norway, a distance of about 5,000 kilometres, led to a substantial joint Canadian and US defence installation. The Permanent Joint Board on Defence coordinated the installation of anti-aircraft defences, United States Army Air Forces and Royal Canadian Air Force units, barrage balloons, and early warning radar bases at five locations in northern Ontario. An anti-aircraft training facility was established 100 kilometres north of the city on Lake Superior. Most of these defences were deemed excessive and removed by January 1943, leaving only a reduced military base at Sault Ste. Marie. The first Algerine-class minesweeper in the Royal Canadian Navy, HMCS Sault Ste. Marie (J334), was named after the city and served as a convoy escort in the Battle of the Atlantic.
In 1990, the city became a flashpoint in national unity debates when its council, under Mayor Joe Fratesi, passed a resolution declaring English the sole official language for municipal services. This was widely seen as a protest against Quebec Premier Robert Bourassa's use of the notwithstanding clause for language law Bill 101. The resolution was controversial as the city had previously established French as an official language due to its sizable Franco-Ontarian population, and many political figures including Prime Minister Brian Mulroney and Premier David Peterson condemned it. The resolution was struck down by a court ruling in 1994, after Premier Bourassa amended Quebec's language laws. Municipal governance continues to shape the city's direction, with the 2026 budget passing with a 3.87 percent tax increase despite city council slashing its own levy increase to zero. The next municipal election is scheduled for October 26, 2026, and the city actively promotes community engagement through events and initiatives like the annual Hallowe'en Spirit Awards and participation in the national Culture Days celebration from September 18 to October 4, 2026.
Economy and Major Employers
The economy of Sault Ste. Marie has long been dominated by the steel industry. Algoma, formerly known as Algoma Steel and Essar Steel Algoma, remains the city's largest single employer, with 3,500 employees at its main plant and approximately 553 more at an adjacent tube mill operated by Tenaris. The company has experienced significant volatility, declaring bankruptcy twice since the late 1980s due to global competition, which led to large layoffs and required bailouts from the Ontario government. An increased demand for steel from China improved the company's fortunes, and CEO Denis Turcotte was named Canadian CEO of the year in 2006. The company was officially sold to India's Essar Group in June 2007 for $1.6 billion. The Huron Central Railway has been historically crucial for transporting materials for the steel industry, though its operations have faced uncertainty, with owner Genesee & Wyoming announcing an intention to discontinue operations in 2010.
Forestry and wood products constitute another major industrial sector. While St. Mary's Paper has closed and reopened under various owners, the ARAUCO factory, which manufactures wood-based panels and operates an adjacent melamine factory for furniture and cupboards, employs over 110 people, with both factories together employing about 150. Diversification efforts include tourism and the service sector. The city was a participant in the federal Rural and Northern Immigration Pilot program launched in 2019, aimed at attracting skilled workers to northern communities like Sault Ste. Marie, North Bay, Sudbury, Timmins, and Thunder Bay. The business process outsourcing industry previously featured three call centres in the city employing about 1,500 people collectively. The city promotes itself as a destination for festivals, cultural events, and outdoor adventure, leveraging its natural setting and heritage to attract visitors.

Notable Historical Figures and Legal Cases
The history of Sault Ste. Marie is marked by several notable individuals and events that had broader significance. In the late 18th and early 19th centuries, the Johnston family exemplified the multicultural fabric of the fur trade era. John Johnston, a Scots-British fur trader, and his Ojibwe wife Ozhaguscodaywayquay, daughter of a chief, were prominent community members who hosted travellers from both the US and Canada. Their children were taught English, Ojibwe, and French. Their daughter, Jane Johnston Schoolcraft, who married American Indian agent Henry Rowe Schoolcraft, has been recognized as the first Native American poet and writer in the United States. Another significant figure was Francis Clergue, the industrialist whose efforts in the early 1900s helped establish the city as a regional centre for manufacturing and resource development.
The city also gained international notoriety in 1911 due to the trial of Angelina Napolitano, who became the first person in Canada to use the battered woman defence for murder. This legal case brought widespread attention to the community. In the modern era, Mayor Joe Fratesi was a central figure in the 1990 language resolution controversy, which drew condemnation from federal and provincial leaders and highlighted tensions in Canadian language politics. These individuals and events illustrate the city's role in broader social, cultural, and legal narratives within Canada, connecting its local history to national stories.
