Putting it all together

In this unit you have studied war, conscription, internment, strikes, women's rights, Indigenous resistance, immigration and culture. Now you will act like a historian and investigate one big question:

To what extent did Canada "come of age" between 1914 and 1929?

There is no single right answer. Historians disagree. Your job is to build a well-supported argument. This lesson walks through Strand A, Historical Inquiry and Skill Development, step by step.

The historical inquiry process. Historians often loop back: a new source can send you back to change your question.

Step 1: Formulate questions (A1.1)

Break the big question into smaller ones. Come of age could mean independence from Britain, national unity, a distinct identity, or fair citizenship for everyone. So ask:

  • How much control did Canada gain over its foreign policy? (political)
  • Did the war unite or divide Canadians? (social)
  • Did all people in Canada share in the new national identity? (perspective)

Step 2: Gather and organize evidence (A1.2)

Collect evidence from primary sources (treaties, speeches, letters, posters, census tables, photographs, oral histories) and secondary sources (textbooks, historians' articles, museum websites). Organize it in a chart with columns: Evidence / Source / For or against / Which group? Look deliberately for the voices of Indigenous peoples, women, workers, French Canadians and racialized communities.

Step 3: Assess and analyse (A1.3, A1.4)

For each source, ask O-P-C-C: origin, purpose, content, corroboration. Use tools such as timelines, cause-and-consequence charts, maps and graphs (for example, the immigration and election data in this unit).

Step 4: Use the concepts and evaluate (A1.5, A1.6)

  • Significance: which developments mattered most, to whom, and for how long?
  • Cause and consequence: what caused Canada's growing autonomy?
  • Continuity and change: what changed between 1914 and 1929, and what did not?
  • Perspective: would a Franco-Ontarian teacher, a First Nations veteran, a Chinese Canadian merchant and a Toronto factory owner answer the same way?

Then weigh the evidence and decide: to what extent? (completely, largely, partly, hardly).

Step 5: Communicate and cite (A1.7)

Choose a format that suits your audience: an essay, a podcast script, a museum exhibit, an infographic or a presentation. Use proper historical terms, a clear thesis, evidence, analysis, a counter-argument and a conclusion. Cite every source (your teacher will tell you which style, often Chicago or MLA). Never copy without credit: that is plagiarism.

Your answer depends on whose experience you weigh.
A continuum helps you weigh evidence. Placing your judgement somewhere between the ends is how you answer a "to what extent" question.
Worked example

Modelled example: From evidence to thesis paragraph

Write a thesis and one body paragraph for: "To what extent did Canada come of age between 1914 and 1929?"

  1. Sort the evidence into categories: autonomy (Versailles, Chanak, Halibut Treaty, Balfour Report, King-Byng), unity (conscription crisis, Regulation 17, Winnipeg strike), inclusion (women's vote vs. Indian Act changes, Chinese exclusion, internment).
  2. Decide the overall judgement: Canada gained a lot of independence from Britain, but did not become united or fair for all.
  3. Write the thesis: "Between 1914 and 1929, Canada largely came of age as an independent nation in its relations with Britain, but it did not come of age as a united or inclusive society, since conscription divided French and English Canadians and government policy excluded or harmed First Nations, Chinese Canadians and other groups."
  4. Body paragraph (autonomy): topic sentence → evidence 1 (Chanak 1922: King said Parliament would decide) → evidence 2 (Halibut Treaty 1923: first treaty signed alone) → evidence 3 (Balfour Report 1926: "equal in status") → analysis (each step moved decisions from London to Ottawa) → link back to thesis.
  5. Counter-argument: Canada still could not amend its own constitution, and the Privy Council in Britain was still its highest court, so independence was not yet complete (Statute of Westminster, 1931).
  6. Cite each source, for example the Canadian Encyclopedia article on the Halibut Treaty, or a primary document.

A strong inquiry answer has a nuanced thesis ("largely... but not..."), specific evidence with dates, analysis that explains why the evidence matters, a counter-argument, and citations.

Citation basics

A simple Chicago-style footnote for a website looks like this:

  1. "Halibut Treaty," The Canadian Encyclopedia, accessed 14 October 2026, https://www.thecanadianencyclopedia.ca/.

For a book: Author First Last, Title (City: Publisher, Year), page. Always record source details while you research; finding them again later is hard.

Skills that travel (A2)

  • Transferable skills (A2.1, A2.2): analysing sources, judging credibility, organizing information, writing arguments, debating respectfully, and understanding other perspectives. You will use them in English, science reports, civics and the workplace.
  • Current events (A2.3): when you see a news story about an immigration policy debate, a labour strike, a land claim, a war or an apology from a government, ask the historian's questions: What are the causes? Whose perspectives are reported? What does the history tell us?
  • Careers (A2.4): historians' skills are used by archivists, museum curators, journalists, lawyers (including those working on treaty and land claims), policy analysts, teachers, genealogists, heritage planners, librarians and researchers in government and business.
Just for fun

Why did the historian refuse to believe the rumour?

It couldn't cite a single source. (Historians also refuse to believe their own memory about where they put their notes, which is why they write citations as they go.)

Hands-on activity

Mini-inquiry and family museum exhibit

You need: paper or poster board, markers, a device for research with a grown-up, and about two hours over a few days.

Possible questions (or write your own with your grown-up):

  • How significant was the Halifax Explosion for Halifax's communities, including Africville and the Mi'kmaq of Turtle Grove?
  • To what extent did the 1920s improve life for women in my province?
  • How did Black Canadians build community in the 1920s?
  • How did First Nations organize to protect their rights between 1914 and 1929?

Steps:

  1. Choose one question.
  2. Find at least four sources: two primary, two secondary. Record citations as you go.
  3. Fill in an evidence chart (evidence / source / for or against / whose perspective).
  4. Write a thesis and make a one-poster exhibit with a title, your thesis, three pieces of evidence (with images or quotes), one counter-point and a source list.
  5. Present your exhibit to your family in three minutes, then answer one question from them.

Look for: a focused question, a clear thesis, accurate evidence with dates, at least one perspective that is often left out, and correct citations.

For parents and teachers

Big idea: This lesson pulls the unit together through Strand A: Historical Inquiry and Skill Development (A1.1–A1.7, A2.1–A2.4). It asks students to build an argument about the whole period, drawing on B3.1 (individuals and groups), B2.2 (autonomy) and B1.4 (wartime impacts).

How to help: The mini-inquiry and family museum exhibit can be spread over a week. Be the audience: ask your teen one challenging question ("What would someone who disagrees say?"). Help them record citations as they go.

Looking ahead: These inquiry skills carry into Grade 11 and 12 history courses and into English, civics and social sciences.

Common difficulties: Writing a thesis that only describes; using evidence without explaining why it matters; forgetting counter-arguments; leaving citations until the end.
