Part 8: The Great War and a Nation Comes of Age (1914–1919)
Reading time: 22–30 minutes
When Britain declared war on Germany on August 4, 1914, Canada, as part of the British Empire, was automatically drawn into what became the First World War. Few Canadians expected the conflict to last more than a few months. Instead, it became one of the deadliest wars in human history.
More than 620,000 Canadians and Newfoundlanders served during the war, despite Canada’s population of only about eight million people. Over 66,000 lost their lives, and another 172,000 were wounded. Their sacrifices profoundly changed Canada’s international standing, strengthened its sense of national identity, and accelerated political and social change at home.
This chapter explores the battles, tragedies, and milestones that transformed Canada from a self-governing Dominion into a nation increasingly recognized on the world stage.

71. Canada Enters the First World War (1914)
What Happened?
Following Britain’s declaration of war, thousands of Canadians volunteered almost immediately.
Recruitment centres quickly filled with:
- Farmers
- Factory workers
- Teachers
- Students
- Indigenous volunteers
- Recent immigrants
The first Canadian troops sailed for Europe in October 1914.
Why It Matters
The First World War became the largest military commitment in Canadian history to that point and dramatically expanded the role of the federal government.
72. The Second Battle of Ypres (1915)
In Belgium, Canadian troops faced one of the war’s first large-scale poison gas attacks.
German forces released chlorine gas across Allied positions.
Although lacking proper protective equipment, Canadian soldiers held their lines under horrific conditions.
Lasting Impact
The courage displayed at Ypres earned Canadian soldiers an international reputation for determination and resilience.
Interesting Fact
Many soldiers survived only by breathing through cloth soaked in water or urine, which provided limited protection against chlorine gas.
73. The Battle of the Somme (1916)
The Somme Offensive became one of history’s bloodiest battles.
Canadian divisions joined Allied forces attempting to break German defensive lines.
Months of fighting produced enormous casualties while gaining only limited territory.
Why It Matters
The Somme demonstrated the devastating realities of modern industrial warfare, including machine guns, artillery bombardments, and trench combat.
74. The Battle of Vimy Ridge (1917)
Between April 9 and April 12, 1917, all four divisions of the Canadian Corps fought together for the first time.
Their objective was Vimy Ridge in northern France.
Using detailed planning, underground tunnels, creeping artillery barrages, and extensive training, Canadian forces successfully captured the heavily fortified ridge.
Lasting Impact
Many historians consider Vimy Ridge a defining moment in Canadian history because it showcased Canada’s growing military capability and strengthened national pride.
Interesting Fact
The Canadian National Vimy Memorial, unveiled in 1936, honours more than 11,000 Canadians who died in France with no known grave.
75. The Halifax Explosion (1917)
On December 6, 1917, the French cargo ship SS Mont-Blanc, carrying thousands of tonnes of explosives, collided with the Norwegian vessel SS Imo in Halifax Harbour.
The resulting explosion devastated much of the city.
Nearly:
- 2,000 people were killed.
- About 9,000 were injured.
- Thousands of buildings were destroyed or damaged.
Why It Matters
It remains one of the largest non-nuclear explosions in history and the deadliest disaster in Canadian history.
76. The Conscription Crisis Divides Canada (1917)
As casualties mounted, voluntary enlistment declined.
Prime Minister Sir Robert Borden introduced compulsory military service through the Military Service Act.
The policy proved deeply controversial.
Many English Canadians supported conscription, believing reinforcements were essential.
Many French Canadians opposed it, arguing they had little connection to Britain’s European war.
Lasting Impact
The Conscription Crisis intensified divisions between English- and French-speaking Canadians that would influence Canadian politics for decades.
77. The Battle of Passchendaele (1917)
Canadian troops were ordered to capture the village of Passchendaele in Belgium after earlier Allied attacks had failed.
Soldiers advanced through:
- Deep mud
- Constant shellfire
- Flooded trenches
- Ruined landscapes
The Canadians eventually secured the objective but suffered more than 15,000 casualties.
Why It Matters
Passchendaele became a symbol of the immense human cost of trench warfare.
78. Canada’s Hundred Days Campaign (1918)
During the final months of the war, Canadian forces participated in a series of successful offensives known as Canada’s Hundred Days.
Major victories occurred at:
- Amiens
- Arras
- Canal du Nord
- Cambrai
- Mons
Canadian troops gained a reputation as some of the Allied Army’s most effective fighting forces.
Lasting Impact
Their success contributed significantly to Germany’s eventual surrender on November 11, 1918.
79. The Spanish Influenza Pandemic (1918–1919)
As soldiers returned home, Canada faced another deadly crisis.
The Spanish Flu spread rapidly across the country.
Communities responded by:
- Closing schools
- Cancelling public gatherings
- Requiring isolation
- Establishing emergency hospitals
Approximately 50,000 Canadians died during the pandemic.
Why It Matters
The pandemic exposed weaknesses in Canada’s public health system and influenced future healthcare planning.
80. Canada Signs the Treaty of Versailles (1919)
Although Canada remained part of the British Empire, its wartime contributions earned international recognition.
Canada signed the Treaty of Versailles separately from Britain and became an original member of the League of Nations.
Lasting Impact
These developments marked an important step toward Canada’s growing independence in international affairs.
Life on the Home Front
While soldiers fought overseas, Canadians at home contributed through:
- Victory Bond campaigns
- Food production
- Munitions manufacturing
- Nursing
- Volunteering
- Supporting military families
Women entered factories in unprecedented numbers, accelerating social changes that would continue after the war.
Did You Know?
- More than 620,000 Canadians and Newfoundlanders served during the First World War.
- Over 66,000 Canadians lost their lives in the conflict.
- More than 172,000 were wounded.
- The Halifax Explosion generated a blast so powerful it was felt over 200 kilometres away.
- The Christmas tree sent annually from Nova Scotia to Boston commemorates the assistance Massachusetts provided after the Halifax Explosion.
Key Takeaways
The First World War transformed Canada politically, socially, and internationally. Canadian soldiers earned global respect through their performance in battles such as Vimy Ridge and the Hundred Days Campaign, while tragedies like the Halifax Explosion and the Spanish Flu left lasting scars at home.
By signing the Treaty of Versailles and joining the League of Nations in its own right, Canada demonstrated that it was no longer simply a British colony—it was emerging as an independent nation with an increasingly influential voice in world affairs.
