Not a superpower, but not powerless
After 1945, Canada had one of the largest navies and air forces in the world and an economy that had not been bombed. It was nowhere near as powerful as the United States or the Soviet Union, but it was not small either. Canadian leaders described Canada as a middle power: a country that could not get its way by force, but could have real influence through cooperation, diplomacy and international organizations.
The years from about 1945 to 1957 are sometimes called the "golden age" of Canadian diplomacy. Canadian diplomats helped create the United Nations (1945) and NATO, and they built a reputation as helpful, fair-minded problem-solvers. In this lesson you will judge whether that reputation was earned.
A middle power uses many tools together. Canada used each of these between 1945 and 1982.The Suez Crisis, 1956
The Suez Canal in Egypt links the Mediterranean Sea and the Red Sea. Britain and France had controlled the company that ran it. In July 1956, Egypt's president, Gamal Abdel Nasser, nationalized the canal (took it over for Egypt). In October and November 1956, Israel, Britain and France attacked Egypt. The Soviet Union threatened to get involved, and the U.S. was angry with its own allies. A small war could have grown into a much bigger one.
Canada's Secretary of State for External Affairs, Lester B. Pearson, proposed a solution at the UN: a United Nations Emergency Force (UNEF) that would stand between the armies while the invaders withdrew. The UN agreed. UNEF was commanded by a Canadian, General E. L. M. Burns, and Canada sent troops. In 1957 Pearson won the Nobel Peace Prize, the first Canadian to do so.
Two perspectives inside Canada: many Canadians were proud. Others, especially people with strong ties to Britain, were upset that Canada had not supported Britain. The Conservatives under John Diefenbaker criticized the government, and they won the 1957 election.
Each step caused the next. Pearson's idea turned a dangerous crisis into the first large UN peacekeeping force.Peacekeeping becomes part of Canada's identity
After Suez, Canadians served in many UN missions, for example in the Congo (1960–1964) and in Cyprus, where Canadian peacekeepers served from 1964 to 1993. Peacekeeping meant monitoring ceasefires, patrolling buffer zones and building trust. It was dangerous work: Canadian peacekeepers have died on missions.
Peacekeeping became a source of national pride and part of how many Canadians saw their country. Historians also point out that Canada spent far more on its NATO forces in Europe than on peacekeeping, and that peacekeeping did not always succeed. Pride in a role and the evidence of that role are not always the same thing.
Harder tests: nuclear weapons, Cuba and Vietnam
- The Cuban Missile Crisis (October 1962): the U.S. discovered Soviet nuclear missiles in Cuba. Prime Minister Diefenbaker hesitated for days before putting Canadian forces on full alert, partly because he resented not being consulted. Many Canadians and Americans were angry at the delay; others agreed that Canada should not simply follow the U.S.
- Nuclear warheads (1963): Canada had bought Bomarc missiles that were designed to carry nuclear warheads, but Diefenbaker's government could not decide whether to accept them. The issue helped bring down his government. Pearson, now Liberal leader, agreed to accept the warheads and won the 1963 election.
- Vietnam: Canada did not send combat troops to the Vietnam War. It served on international commissions that monitored ceasefires (the ICSC from 1954 and the ICCS in 1973). In a 1965 speech in the U.S., Pearson suggested a pause in the American bombing of North Vietnam, which angered President Lyndon Johnson. At the same time, Canadian companies sold materials used by the U.S. military, and tens of thousands of young Americans who opposed the war or the draft moved to Canada.
New directions in the 1960s and 1970s
- Foreign aid: the Canadian International Development Agency (CIDA) was created in 1968 to run Canada's aid to developing countries.
- La Francophonie: Canada joined French-speaking countries in founding the Agency for Cultural and Technical Co-operation in 1970, an early form of La Francophonie. This also showed Canada's bilingual identity abroad.
- China: in 1970, under Prime Minister Pierre Trudeau, Canada recognized the communist People's Republic of China, before the U.S. did.
- Nuclear weapons: Canada signed the Nuclear Non-Proliferation Treaty in 1968. In 1974 India tested a nuclear device using plutonium produced in a research reactor Canada had supplied for peaceful use, which shocked Canadians and led to stricter rules.
- Humanitarian crises: during the war in Biafra (Nigeria, 1967–1970), Canadian church groups and citizens organized relief flights, while the government was slower to act.
Worked exampleModelled example: Continuity or change?
Was Canada's international role between 1945 and 1982 mostly continuity or mostly change? Build an answer.
- Set a starting point: before 1939, Canada had a small military, few diplomats and usually followed Britain's lead.
- Evidence of change: Canada helped create the UN and NATO, invented large-scale UN peacekeeping, created CIDA, and made independent choices (no troops in Vietnam, recognizing China in 1970).
- Evidence of continuity: Canada still stayed close to a great power, but now it was the U.S. instead of Britain (NORAD, NATO, Bomarc warheads). Canada stayed a loyal Western ally throughout the Cold War.
- Weigh it: the tools and the partner changed a lot, but Canada's basic position (a smaller ally of a powerful friend) continued.
- Write a thesis that shows both.
Sample thesis: "Between 1945 and 1982, Canada's international role changed dramatically as it became an active middle power through the UN, peacekeeping and aid, but there was also important continuity: Canada remained the junior partner of a great power, only now that partner was the United States rather than Britain."
Just for funA true story: Lester Pearson's friends and family called him "Mike". The nickname came from a flight instructor in the First World War, who thought "Lester" did not sound tough enough for a pilot. So a Nobel Peace Prize winner got his nickname in an air force.
Hands-on activityDesign a peacekeeping memorial
You need: paper, pencil or pencil crayons, and (optional) a device to look up Canadian peacekeeping missions with a grown-up.
In Ottawa there is a real Peacekeeping Monument called Reconciliation (unveiled in 1992). Imagine your town is building a small memorial to Canadian peacekeepers.
- Choose one mission from this lesson (Suez/UNEF, Congo or Cyprus).
- Sketch a design and label three symbols in it. Explain what each symbol represents.
- Write a short plaque (40 to 60 words) that explains why the mission was historically significant. Use at least one date and one fact from this lesson.
- Add one sentence on the plaque that admits a limitation or cost of peacekeeping. Good history is honest.
What to look for: accurate facts, symbols with clear meanings, and a balanced plaque.
Your turn
A country that is not a superpower but uses diplomacy, alliances and international organizations to have real influence.
2Why was the Suez Crisis of 1956 dangerous for the whole world?
Britain, France and Israel attacked Egypt; the USSR threatened to intervene and the U.S. was angry with its allies, so the conflict could have grown into a larger war between superpowers.
3What was Pearson's solution?
A United Nations Emergency Force (UNEF) to separate the armies while the invaders withdrew.
4What did Pearson win in 1957?
5Why was Diefenbaker criticized during the Cuban Missile Crisis?
He delayed putting Canadian forces on full alert, which angered the U.S. and many Canadians.
6Did Canada send combat troops to Vietnam? What did it do instead?
No. It served on ceasefire monitoring commissions (ICSC, ICCS), while some Canadian companies sold war materials to the U.S. and many American war resisters came to Canada.
Ran Canada's foreign aid to developing countries (created 1968).
More practice: warm-up
1Which Egyptian leader nationalized the Suez Canal?
2Which Canadian general commanded UNEF?
3In what year did Canadian peacekeepers begin serving in Cyprus?
4In what year did Canada recognize the People's Republic of China?
5Name the missiles at the centre of the 1963 nuclear warhead debate.
More practice: on your own
1Explain why some Canadians were unhappy with Pearson's role in Suez.
Many Canadians with strong British ties felt Canada should have supported Britain, its traditional partner, instead of working against Britain's actions at the UN.
2How did the nuclear warhead issue affect Canadian politics in 1963?
Diefenbaker's government was divided and indecisive about accepting warheads for the Bomarc missiles; it lost a vote in the House and then the election. Pearson, who agreed to accept the warheads, became prime minister.
3Why might the 1974 Indian nuclear test have shocked Canadians?
It used plutonium produced in a reactor Canada had supplied for peaceful purposes, so Canada's help had contributed to a nuclear weapons test, against Canada's goal of preventing the spread of nuclear weapons.
4Give one piece of evidence that Canada acted independently of the U.S. and one that it followed the U.S.
Independent: no combat troops in Vietnam; recognized China in 1970; kept relations with Cuba. Followed: joined NORAD; accepted nuclear warheads in 1963; stayed a close Cold War ally.
5Why do historians say pride in peacekeeping should be checked against evidence?
Canada spent more on NATO forces than on peacekeeping, and missions did not always succeed. A national story can be true in part but exaggerated; evidence tells us how big the role really was.
Challenge
1Assess the historical significance of the Suez Crisis for Canada. Use at least two criteria.
Impact at the time: it helped prevent a wider war and created the first large UN peacekeeping force. Lasting effect: peacekeeping became a long-term Canadian role and part of Canadian identity for decades. Revealing: it showed Canada acting independently of Britain. It is highly significant.
2Use historical perspective: how might an American official and a Canadian peace activist each have viewed Diefenbaker's delay in October 1962?
American official: a dangerous failure to support an ally under threat, which weakened North American defence. Peace activist: a sensible refusal to rush toward nuclear war and proof Canada would not blindly follow the U.S.
3Was the "golden age of Canadian diplomacy" golden for everyone? Write a short argument.
Sample: it was golden for Canada's international reputation (UN, NATO, Suez), but at home the same years included the Red Scare and continued discrimination in immigration and against Indigenous peoples. A country's success abroad did not mean equal rights at home, so the label fits foreign policy better than Canadian life as a whole.
Check your understandingQuiz
1. What does it mean to call Canada a middle power?
2. Who proposed the UN Emergency Force during the Suez Crisis?
3. Which countries attacked Egypt in 1956?
4. What was Canada's role in the Vietnam War?
5. Which event helped bring down Diefenbaker's government in 1963?
6. Which is the best example of continuity in Canada's foreign policy, 1945–1982?
For parents and teachersBig idea: This lesson covers Canada's international participation in the Cold War era (D2.4), parts of Canada–U.S. relations (the Cuban Missile Crisis, Bomarc, Vietnam: D2.5), and Lester B. Pearson's contribution (D3.1). The thinking skill is continuity and change and building a thesis (A1.5, A1.6).
How to help: Ask: "Was Canada's peacekeeping reputation earned?" and push for evidence on both sides. If you know anyone who served as a peacekeeper, an interview would be powerful.
Common difficulties:
- Treating peacekeeping as Canada's only military role. Remind students of NATO, NORAD and Korea.
- Confusing Pearson (Liberal; Suez; prime minister 1963–1968) with Diefenbaker (Progressive Conservative; prime minister 1957–1963).
- Writing a thesis that only lists facts. A thesis makes a claim that can be argued.
