Part 3: Empires at War (1702–1763)
Reading time: 20–25 minutes
The first half of the 18th century was one of the most turbulent periods in Canadian history. France and Great Britain were locked in a global struggle for power, and North America became one of its most important battlegrounds. Colonies changed hands, Indigenous nations were drawn into imperial rivalries, and ordinary settlers found themselves living on the front lines of conflict.
By the end of this period, France’s 150-year presence in mainland Canada had come to an end, forever changing the country’s political, cultural, and linguistic future.

21. Queen Anne’s War Reaches North America (1702)
What Happened?
Queen Anne’s War was the North American theatre of the War of the Spanish Succession, fought between Britain, France, and their allies.
Although much of the fighting occurred in present-day Atlantic Canada and New England, the conflict affected settlements throughout New France.
French forces and their Indigenous allies launched raids against British settlements, while British colonial militias attacked French positions.
Why It Matters
The war demonstrated that control of North America would depend not only on European armies but also on alliances with Indigenous nations and the ability to control trade routes.
22. The Treaty of Utrecht Redraws the Map (1713)
After more than a decade of fighting, the Treaty of Utrecht brought peace between Britain and France.
Under the treaty, France ceded:
- Acadia (mainland Nova Scotia)
- Newfoundland
- The Hudson Bay region
France retained:
- Île Royale (Cape Breton Island)
- Île Saint-Jean (Prince Edward Island)
- The St. Lawrence Valley
Lasting Impact
Britain significantly expanded its influence in northeastern North America, while France began strengthening its remaining colonies.
23. The Fortress of Louisbourg Is Built (1719–1740)
To protect the entrance to the Gulf of St. Lawrence after losing Acadia, France constructed the massive Fortress of Louisbourg on Cape Breton Island.
Louisbourg became one of the largest fortifications in North America.
It featured:
- Thick stone walls
- Dozens of cannons
- Barracks
- Warehouses
- A busy harbour
- Commercial fishing facilities
Interesting Fact
Construction took more than 20 years and cost millions of livres, making it one of France’s most expensive overseas projects.
24. King George’s War Begins (1744)
Another European conflict spread to North America.
British and French colonies once again found themselves at war.
Privateers attacked shipping, frontier settlements faced raids, and Louisbourg became the primary target for British forces.
Why It Matters
The repeated wars weakened both colonial powers and increased tensions leading toward an even larger conflict.
25. Louisbourg Falls to British Colonial Forces (1745)
In an astonishing campaign, soldiers from New England, supported by the Royal Navy, captured Louisbourg after a lengthy siege.
The victory shocked Europe.
However, the fortress was returned to France only three years later under the Treaty of Aix-la-Chapelle.
Lasting Impact
The temporary capture demonstrated Louisbourg’s strategic importance and foreshadowed future British success.
26. The Treaty of Aix-la-Chapelle Restores the Status Quo (1748)
Despite years of costly fighting, the treaty largely restored territorial boundaries to their pre-war positions.
Louisbourg returned to French control in exchange for British gains elsewhere.
Many British colonists were furious, believing their hard-fought victory had been wasted.
Why It Matters
The unresolved rivalry made another war almost inevitable.
27. The Expulsion of the Acadians Begins (1755)
British authorities in Nova Scotia feared that many Acadians—French-speaking settlers who had lived there for generations—might support France during the coming conflict.
Beginning in 1755, thousands of Acadians were forcibly removed from their homes.
Families were separated, villages were burned, and many people died from disease, starvation, or shipwreck during deportation.
Others eventually settled in Louisiana, where their descendants became known as the Cajuns.
Lasting Impact
The Expulsion of the Acadians remains one of the most tragic and significant events in Canadian history.
28. The Seven Years’ War Begins (1756)
Often described as the world’s first global war, the Seven Years’ War was fought across Europe, Asia, Africa, and North America.
In Canada, British and French armies fought for control of New France.
Major battles occurred around:
- Lake Ontario
- Lake Champlain
- Fort Frontenac
- Fort Carillon
- Louisbourg
- Quebec
Why It Matters
Victory in this war would determine which European power controlled much of North America.
29. The Battle of the Plains of Abraham (1759)
On September 13, 1759, British forces under Major General James Wolfe climbed the cliffs west of Quebec City and confronted French troops commanded by Marquis de Montcalm.
The battle lasted less than an hour.
Both commanders suffered fatal wounds.
British victory forced the surrender of Quebec City.
Interesting Fact
Despite the decisive victory, fighting continued for several more years before the war officially ended.
30. The Treaty of Paris Ends New France (1763)
The Treaty of Paris formally ended the Seven Years’ War.
France ceded nearly all of its North American possessions east of the Mississippi River to Britain, while retaining only the small islands of Saint Pierre and Miquelon for fishing rights.
Britain now controlled:
- Quebec
- Acadia
- Cape Breton Island
- The Great Lakes region
- Most of eastern North America
Why It Matters
Although French political rule ended, French language, civil law, religion, and culture endured. These traditions continue to shape modern Canada, particularly in Quebec.
Life During Wartime
For ordinary people, life was uncertain.
Settlers endured:
- Crop failures caused by conflict
- Military occupations
- Heavy taxation
- Supply shortages
- Forced labour on fortifications
- Frequent attacks on frontier communities
Many Indigenous nations faced difficult choices, balancing long-standing alliances while trying to protect their own territories and sovereignty.
Did You Know?
- The Fortress of Louisbourg was considered one of the strongest fortifications in North America.
- General James Wolfe was only 32 years old when he died after the Battle of the Plains of Abraham.
- Marquis de Montcalm died the day after the battle from his wounds.
- The Seven Years’ War was fought on five continents and is often called the first true world war.
- Despite Britain’s victory, French remained the dominant language in much of Quebec.
Key Takeaways
Between 1702 and 1763, Canada became the centre of an imperial struggle between France and Great Britain. Repeated wars devastated communities, shifted borders, and transformed the lives of settlers and Indigenous nations alike. The British conquest of New France in 1763 marked a turning point, but it did not erase French identity. Instead, the coexistence of French and British traditions would become one of Canada’s defining characteristics.
The next chapter explores how Britain governed its new colony, the arrival of Loyalists after the American Revolution, and the events that laid the groundwork for modern Canada.
