Canada

A note on the map before anything else: the border data draws Canada only from 1932, which is 65 years after Confederation. Before 1932 the polygons for Ottawa, Winnipeg and Yellowknife fall inside the British Empire. The entry covers 1867 to the present and explains the gap rather than pretending it away.

At a glance

What is Canada?

A federation created by an act of the British Parliament in 1867, which united four colonies of the former British empire in North America — Ontario, Quebec, Nova Scotia and New Brunswick — into a self-governing dominion. It expanded across the continent by purchase, treaty and annexation: the Hudson's Bay Company's lands in 1870, British Columbia in 1871, Prince Edward Island in 1873, the Arctic islands, Newfoundland in 1949.

Its constitution was, until 1982, a British statute that Canada could not amend itself. That is the paradox at the centre of Canadian sovereignty: a country that governed itself in almost everything, and had to ask London to change its own constitution. The Canada Act of 1982 — assented on 29 March, proclaimed on 17 April — ended that, and added a Charter of Rights and Freedoms that has reshaped Canadian politics ever since.

How did Confederation happen?

Through deadlock, debt and fear. The Province of Canada — Ontario and Quebec — had been governed since 1841 by a union in which the two halves could block each other, and by the 1860s the system had stopped working. The American Civil War alarmed the British colonies, and the Fenian raids of 1866 made defence a practical question. Britain wanted to reduce its colonial commitments; the colonies wanted railways and markets.

The British North America Act was enacted on 29 March 1867 and came into force on 1 July. It divided powers between the federal government and the provinces in sections 91 and 92 — giving the federal government the residue of powers, unlike the United States — and it was designed to be a centralised federation, though the provinces have grown stronger ever since. The 72 Resolutions of the Quebec Conference of 1864 were its draft, and Prince Edward Island stayed out until 1873, when its railway debt made union attractive.

How was the west taken?

By treaty, by survey, by railway and by force, in that order — and the treaties are the foundation of the legal argument that continues today. Between 1871 and 1921, the Crown signed eleven numbered treaties covering most of the prairies and the north. Treaty 1, signed at Lower Fort Garry and ratified on 12 September 1871, promised 160 acres per family of five, a $3 gratuity, a $15 annual annuity and a school on each reserve; the government's negotiator, Joseph Howe, had been instructed to keep the annuity at or below $12.

The Indian Act of 1876 consolidated the legal regime that governed status Indians, and it accumulated prohibitions: the potlatch was banned in 1884, ceremonies in 1895, off-reserve dancing in 1914 and all dancing in 1925. The residential school system was recommended by Nicholas Davin's report of 14 March 1879 — commissioned on 28 January 1879 — and the first three prairie industrial schools opened in 1883. Children were taken from their families, forbidden their languages, and in thousands of cases never returned.

The west was also taken by war. The Red River Resistance of 1869–70 produced Manitoba, after Thomas Scott was court-martialled on 3 March 1870 and shot the next day. The North-West Resistance of 1885 — led by Louis Riel, who had returned from exile — ended at Batoche; Riel was hanged on 16 November 1885, and eight Indigenous men on 27 November. The Métis land provisions — 607,000 hectares for Métis children — were honoured in the breach, and the resistance's defeat was followed by the pass system, imposed in the 1880s without legal authorisation.

How did Canada govern itself?

As a parliamentary federation, with the British model adapted to a continental scale.

The governor general represented the Crown; the prime minister governed with a cabinet drawn from the House of Commons; the provinces had their own legislatures, premiers and jurisdiction over property, education and health. The division of powers in sections 91 and 92 gave the federal government the residue — "peace, order and good government" — which was meant to make Ottawa dominant and in practice made the provinces powerful as the country grew.

The courts decided the balance, and until 1949 the final court was the Judicial Committee of the Privy Council in London, which repeatedly ruled in favour of the provinces. That is why Canada is one of the most decentralised federations in the world, and why provincial premiers — in health care, in resources, in constitutional negotiations — are national political figures.

What was the National Policy?

A tariff, a railway and a settlement programme. John A. Macdonald's government introduced the National Policy in the budget of 14 March 1879: protective tariffs on manufactured goods to keep Canadian industry alive against American competition, a transcontinental railway to bind the country together, and immigration to fill the west.

The railway was the centrepiece. The Canadian Pacific Railway was incorporated on 16 February 1881 with a subsidy of $25 million, 25 million acres of land, $37 million for surveys and a twenty-year monopoly on through traffic; the last spike was driven on 7 November 1885. The CPR made Confederation physically possible, and it made the prairies a wheat colony of the east — which is exactly what the National Policy intended.

How did Canada expand?

By purchase, treaty, annexation and negotiation. The Hudson's Bay Company sold Rupert's Land and the North-Western Territory to the Crown in 1869–70 for £300,000, and the new territory became the Northwest Territories and Manitoba. British Columbia joined in 1871 on the promise of a transcontinental railway within ten years; Prince Edward Island joined in 1873 with its railway debt paid. The Arctic islands were transferred in 1880, and Newfoundland — which had rejected Confederation twice — joined in 1949 after a referendum and a narrow vote in its legislature.

The expansion was not consensual everywhere. The Métis and the Indigenous nations of the prairies were not consulted about the transfer of their homelands, and the treaties that followed were presented as land surrenders; whether they were understood that way by the people who signed them is the central question in the litigation that continues today.

Who came?

Immigrants, in waves, and not all of them welcome. The Laurier boom brought 3,059,220 arrivals between 1896 and 1914, out of 4,537,252 for the whole period 1867–1914, with a peak of 400,870 in 1913. The prairie provinces grew from 419,512 people in 1901 to 1,328,121 a decade later — an increase of 217 per cent.

Clifford Sifton, the minister responsible, wanted "stalwart peasants in sheep-skin coats" — preferably British, American or northern European. The policy was explicitly racial. Chinese immigrants paid a head tax from 1885, rising to $500, and were excluded altogether by the Chinese Immigration Act of 1923; about 82,000 people paid the tax, contributing some $23 million. The Komagata Maru, a ship carrying 376 Punjabi passengers, was turned away from Vancouver in 1914. Black immigrants from the United States were discouraged by order-in-council, and Jewish refugees fleeing Europe in the 1930s were admitted in numbers so small — about 5,000 between 1933 and 1945 — that a Canadian official's phrase, "none is too many", became the title of a book about it.

What was the Depression like?

Catastrophic, and it shaped everything that came after. The prairies were hit by drought and falling wheat prices at the same time; farm incomes collapsed, relief camps were set up for unemployed men, and the On-to-Ottawa Trek of 1935 ended in a riot in Regina. Immigration fell from 400,870 in 1913 to 14,382 in 1933 — a drop of 96 per cent — and the population growth of the country stalled.

The political result was a set of new parties: the Co-operative Commonwealth Federation in 1932, Social Credit in Alberta, and a Conservative government that lost to Mackenzie King in 1935. The Rowell–Sirois Commission, appointed in 1937 and reporting in 1940, concluded that the provinces could not manage unemployment relief and that the federal government needed a larger share of taxation — the intellectual foundation of the post-war welfare state.

What did the wars do?

They made Canada a nation, and divided it. In the First World War, Canadian divisions fought at Ypres, the Somme, Vimy Ridge and Passchendaele, and in the Hundred Days; the dead are given as 61,000 by some historians and more than 66,000 by Veterans Affairs Canada. Conscription in 1917 — the Military Service Act, with 401,882 men registered and 24,132 reaching France — split the country: the Union government won the election of December 1917 with 153 seats to 82, and riots followed in Quebec.

The Second World War began for Canada on 10 September 1939, a week after Britain declared. Canada sent 1,086,343 men and women into uniform, lost about 44,000 dead, and fought at Hong Kong, Dieppe, Ortona and Juno Beach. Conscription came again in 1944, after a plebiscite in 1942 that Quebec voted against by 72.9 per cent. The war also produced the country's worst refugee policy: the St Louis was turned away in 1939 with 907 Jewish refugees aboard, and 254 of them later died in the Holocaust.

When did Canada become sovereign?

In stages, without a declaration. The Statute of Westminster, assented on 11 December 1931, ended the British Parliament's power to legislate for Canada except at Canada's request, and gave the dominions control of their own foreign policy. It did not settle the constitution: the amending formula remained in London until 1982, and the Judicial Committee of the Privy Council in London remained Canada's final court of appeal until 1949.

Canadian citizenship was created in 1947; Newfoundland joined in 1949. The Canada Act of 1982 patriated the constitution, with an amending formula and the Charter of Rights and Freedoms — sections 25, 33 and 35 are the ones that matter most, protecting Aboriginal rights, allowing legislative override, and recognising existing Aboriginal and treaty rights. The Charter has made the courts a central institution of Canadian politics, and it has made the notwithstanding clause a permanent feature of constitutional debate.

What was Canada's Cold War?

A middle power with a large role. Canada joined NATO in 1949, contributed to the Korean War, and with the United States created NORAD in 1958 to defend the continent against Soviet bombers. It kept troops in Europe for decades, and it invented peacekeeping — Lester Pearson's proposal for a United Nations force during the Suez crisis of 1956 won him the Nobel Peace Prize, and the Canadian military's subsequent reputation rested on it.

The limits were real. The Avro Arrow, an advanced interceptor, was cancelled in 1959 in a decision that became a symbol of Canadian dependence on American defence; the country accepted nuclear weapons under NORAD in the early 1960s after a political crisis; and the defence relationship with the United States has been the constant constraint on Canadian foreign policy ever since.

What was the welfare state?

A post-war settlement built on the assumption of full employment and the memory of the Depression. Unemployment insurance came in 1940, family allowances in 1944, and the Rowell–Sirois report of 1940 had already argued for a stronger federal role in social policy. Medicare began in Saskatchewan in 1962 under Tommy Douglas and became federal policy in 1966; the Canada Pension Plan followed in 1965.

The result was a country with American-style federalism and European-style social programmes, financed by a federal government that had gained the taxing power to pay for them. It was also a country that cancelled its own advanced fighter programme — the Avro Arrow, in 1959 — and bought American weapons instead, a decision that became a symbol of the limits of Canadian sovereignty in defence.

What is the constitution?

Not one document but a set: the BNA Act 1867 and its amendments, the Statute of Westminster, the Canada Act 1982 and the Constitution Act 1982 with its Charter, plus the unwritten conventions of parliamentary government. Until 1982 the amending formula was a British statute, which meant that Canada's constitution could only be changed by the Parliament at Westminster, at Canada's request — the "patriation" question that Trudeau resolved, and that Quebec never accepted.

The Charter changed the country's politics by transferring power to the courts. Sections 1, 7, 15 and 33 structure every rights case; section 35 recognises Aboriginal and treaty rights; section 25 protects them from being overridden by the Charter itself. The notwithstanding clause allows a legislature to override sections 2 and 7–15 for five years, and its use — by Quebec, Ontario and Saskatchewan — is the permanent argument about how much power the courts should have.

What was the Quebec question?

The central domestic question of the last sixty years. The Quiet Revolution of 1960–66 secularised Quebec, built a provincial state and created a nationalist movement; the Royal Commission on Bilingualism and Biculturalism, appointed in 1963, led to the Official Languages Act, in force on 7 September 1969, which made English and French the languages of the federal government.

The Parti Québécois won the provincial election of 1976 with seventy-one of 110 seats, and held a referendum in 1980: the No side won 59.56 per cent, by 2,187,991 votes to 1,485,851, on a turnout of 85.61 per cent. The second referendum, in 1995, was much closer: No won 50.58 per cent, a majority of 54,288 votes on a turnout of 93.52 per cent. The Charlottetown Accord was rejected in 1992 by 54.3 per cent — excluding Quebec's votes, which is a detail the national total conceals. The Clarity Act of 2000 set the federal terms for any future secession negotiation.

What is the economy?

Staples, and the politics of staples. Fur, timber, fish, wheat, minerals, oil and gas — each in its turn has dominated exports and shaped the country's regions: the Atlantic fisheries, the prairie wheat economy, the Ontario and Quebec manufacturing belt, the Alberta oil sands. The National Policy's tariff made manufacturing possible in the east; the free trade agreement with the United States in 1988, and NAFTA in 1994, exposed it to continental competition.

Canada's economy is now dominated by services, resources and real estate, and its politics by the consequences: a housing market that has priced a generation out of ownership, a resource sector that fights carbon pricing, and a federation in which Alberta's oil and Quebec's hydroelectricity give two provinces enormous leverage. The country's largest trading partner is the United States, by a margin that makes the relationship an issue in every election.

What did the Quiet Revolution change?

Everything in Quebec, and therefore everything in Canada. The provincial state took over education and health from the Church, nationalised hydroelectricity, built a modern civil service and created a secular, francophone bourgeoisie. The Church's influence collapsed; birth rates fell; and the new elite demanded autonomy, then sovereignty.

The federal response was bilingualism and, later, the Charter. The Official Languages Act made French an official language of the whole federal state, not just of Quebec; the Charter entrenched minority language education rights; and the 1982 Constitution Act recognised Quebec as a distinct society in spirit but not in law. The result is a country in which French is genuinely official and in which Quebec's place remains unsettled.

What happened to Indigenous peoples?

The truth came out slowly, and officially. The White Paper of 1969 proposed to abolish Indian status and treaty rights; it was withdrawn after Indigenous opposition. The Calder decision of 1973 recognised Aboriginal title in principle; section 35 of the 1982 Constitution Act recognised and affirmed existing Aboriginal and treaty rights; the Oka crisis of 1990 was a standoff over a golf course expansion on Mohawk land, and it changed the country's politics.

The residential schools were the centre of it. The Royal Commission on Aboriginal Peoples reported in 1996; litigation and the Indian Residential Schools Settlement Agreement followed; the Truth and Reconciliation Commission reported in 2015 with 94 Calls to Action; and in 2008 the government apologised for a system that had taken more than 150,000 children into one hundred and thirty-two schools. In 2021, ground-penetrating radar at former school sites in Kamloops and elsewhere found evidence of unmarked graves, and the country's understanding of its own history shifted again. The United Nations Declaration on the Rights of Indigenous Peoples was adopted into Canadian law in 2021.

What about the Arctic?

Sovereignty over the north has been a Canadian obsession since the 1880s, when the government began patrolling the Arctic islands and sponsoring expeditions. The Inuit were relocated to the high Arctic in the 1950s to assert sovereignty, a policy that was later acknowledged as a grievance and compensated; the territory of Nunavut was created in 1999, with an Inuit government and a land-claim agreement.

The Arctic is now the front line of climate change: the sea ice is retreating, the Northwest Passage is becoming navigable, and Canada's claim to the passage as internal waters is disputed by the United States and others. The map's polygons for the north are among the least accurate in the dataset, which is a small illustration of the same problem.

What is Canada's place in the world?

A middle power that punches above its weight in some forums and depends on the United States in others. It is a member of the G7 and the G20, a founding member of the United Nations and NATO, a signatory of the Paris Agreement and the Convention on the Rights of Persons with Disabilities, and a country whose foreign policy has been shaped by its relationship with Washington since the Second World War.

Its reputation rests on peacekeeping, development aid and multilateralism; its record includes the 1994 Rwandan withdrawal, the 2003 refusal to join the Iraq war, and a climate policy that has never met its own targets. It is a country that defines itself against the United States culturally and depends on it economically, and that tension is the oldest theme in Canadian politics.

What about the monarchy?

The British monarch is Canada's head of state, represented by a governor general who performs the ceremonial functions of the Crown: opening parliament, acceding to legislation, appointing the prime minister and dissolving parliament. The arrangement is legal, not sentimental — the Crown is the legal person of the state, and abolishing the monarchy would require the consent of every province under the amending formula.

Support for abolition has grown slowly and has never reached the point of action; the coronation of 2023 revived the debate, and the cost of the governor general's office is a perennial complaint. The Crown's practical importance is in the reserve powers and in the treaties: the Crown is the treaty partner of the Indigenous nations, which is one reason the monarchy cannot simply be replaced.

What is Canada now?

A liberal democracy of about forty million people, with a resource economy, a housing crisis, an ageing population and a contested place in the world. It is a middle power that depends on the United States for trade and defence, a monarchy whose monarch lives abroad, and a federation whose provinces are increasingly assertive. It has a carbon price — $10 a tonne in 2018, rising to $170 by 2030, and zero after 31 March 2025 — and a climate policy that is fought over in every election.

Its politics are now dominated by three questions: housing, immigration and climate. Immigration has kept the population growing to about forty million while the birth rate falls, but the surge of temporary residents after 2021 has made it the most contested policy in the country. Housing prices in Toronto and Vancouver have made ownership impossible for a generation, and the federal and provincial governments blame each other. Carbon pricing has become the defining partisan divide, and the 2025 decision to end the consumer carbon charge was a retreat from the policy that had defined the previous decade.

It is also a country that has begun, haltingly, to reckon with how it was made. The treaties, the schools and the pass system are no longer marginal subjects in Canadian history; they are the subject.

Why does the map start in 1932?

Because of a decision in the border dataset, not a decision in Ottawa. Canada exists in the Cliopatria polygons only from 1932; before that, the territory falls inside the British Empire's polygons, and Ottawa, Winnipeg and Yellowknife are drawn as imperial rather than Canadian.

Seshat's own polity record for Canada begins in 1867, so 1932 is a polygon convention rather than a dating of the country. Cliopatria publishes no rule for it. The only candidate with a mechanism is the Statute of Westminster, assented on 11 December 1931, whose first full year is 1932 — and the same dataset starts New Zealand in 1948, the year after its adoption of the statute, which supports the inference. It remains an inference. What is certain is that the map's Canada is a 1932-onward Canada, and that the entry has to say so.
