[88] The treaty that ended the war marked a major change in European relations with the maritime Algonquians, as it granted the British the right to settle in traditional Abenaki and Mi'kmaq lands.
While maritime Algonquians swiftly allied with the French, many Indigenous groups in the Great Lakes region hesitated to join, preferring to maintain trade ties with the British.

[116] Five British provincial corps, augmented by additional unincorporated units and Loyalist associators, were raised in the Canadian colonies to assist in its defence and to harass the American frontier.
[130] Despite successfully defending Quebec and Nova Scotia, British military defeats in the Thirteen Colonies led to their surrender in 1781 and the subsequent recognition of the independent US republic in the Treaty of Paris of 1783.
[139] The American retreat facilitated Brock's alliance with Shawnee chief Tecumseh and provided him with the excuse to abandon his orders to maintain a defensive posture within Upper Canada.

[169] The Upper Canada Rebellion, led by William Lyon Mackenzie, primarily comprised disaffected American-born farmers who opposed the preferential treatment of British settlers in the colony's land grant system.
The attacks sparked a month-long armed standoff in the British Columbia Interior, after a group predominantly made up of American prospectors marched from the colonial capital of New Westminster to quell the resistance in the Crown's name.
[185] By the mid-1860s, British North American colonies faced mounting pressure to assume their own defences as the UK sought to alleviate themselves of the cost of defending them and to redeploy troops to more strategic areas.
Although some questioned the need to unite post-American Civil War, subsequent raids by Fenians made more people in British North America favourable to Canadian Confederation, which was eventually realized in 1867.
Consequently, British forces withdrew from Canada, except for Halifax and Esquimalt, where garrisons of the Pacific and North America and West Indies stations remained for reasons of imperial strategy.

[136] The greater degree of autonomy Canada saw after the First World War, coupled with public reluctance to participate in further imperial conflicts, led the Canadian government to refuse a British request for military aid during the 1922 Chanak Crisis.
[274] Although Canada was a significant contributor to the war, it played no major role in its strategic planning, as Prime Minister William Lyon Mackenzie King refrained from involvement.
The fall of Belgium and France to Germany in June 1940 led Canada to drastically expand its military spending and armed forces, and implement conscription for home defence.
