With the end of the Seven Years’ War in 1763, Britain replaced France as the preeminent colonial power in the land that is now Canada. In doing so they assumed the legacy of Aboriginal-French relations. Relations under British rule continued for some decades along the lines established during the French era. From the Great Lakes eastward, commercial and military interactions dominated the interchanges between Indigenous and immigrant peoples. In the 19th century these links would be replaced by a different form of association — policies that advocated assimilation, subjugation and even destruction — as European settlement pushed westward.

The Age of Alliance

In eastern Canada, British strategic considerations meant that Aboriginal nations remained desirable as allies from the American Revolution to the 1820s. Throughout this period the British tried to maintain alliances with interior nations, while most Aboriginal peoples found alliance with the British more attractive than either neutrality or support for the Americans.

The reasons for this support can be seen most clearly in the brief career of the Odawa chief Pontiac, who forged a common front of First Nations of the southern interior after the Seven Years' War. Pontiac's forces sought to resist the expansion of Anglo-American agricultural settlement from the seaboard colonies. This strategy remained popular among many Aboriginal groups, including the Shawnee leaders Tecumseh and his brother Tenskwatawah (also known as The Prophet) who supported the British during the early stages of the War of 1812. Tecumseh and Tenskwatawah’s aim was to establish a self-governing Aboriginal state west of European settlement.To defend these lands from American expansion, they chose an alliance with the British, who made promises to support an autonomous Confederacy of Indigenous nations. After the War of 1812, however, these agreements became much less advantageous to the British, who abandoned their promises, allowing virtually unchecked westward American expansion.

A lasting consequence of the age of alliance was the Royal Proclamation of 1763. Issued by the imperial government to delineate the boundaries and stipulate the governance of its new colony, Québec, the Proclamation also attempted to control increasing tensions in the interior of the continent. The Royal Proclamation forbade European settlement and regulated trade west of European colonies, and recognized these interior lands as Aboriginal "hunting grounds." Under the Proclamation only the Crown could accept surrenders for such lands. This requirement laid the basis for the system of land-surrender treaties that was pioneered in Ontario in the late 18th and 19th centuries, and was replicated on the prairies after Confederation and in the north in the 20th century.The Proclamation did not, however, cover eastern settlements, where Mi’kmaq, Maliseet, Passamaquoddy, Innu, Wendat, Algonquin, Haudenosaunee and other peoples interacted with imperial administrations through other agreements, or were subject to encroachment and marginalization.

Commercial Partnership

The British inherited from the French a commercial partnership with Indigenous peoples, which moved westward and northward after the 1760s. In the lands granted to the Hudson's Bay Company (HBC) in 1670, an influential new type of relationship developed after the HBC began to move inland and establish posts from the 1770s onward. The HBC and the Montréal-based North West Company, who amalgamated under the name of the former in 1821, traded with the Cree, Assiniboine, Saulteaux and others in the western interior, although epidemic disease, combined withthe abuse of alcohol and violence, led to severe losses to population and culture.

A vitally important social consequence of the western trade was the emergence of the Métis, the offspring ofunions between European traders and First Nations women on the Plains. Two subdivisions were present: the country-born were offspring of English or Scottish traders and First Nations women, while the Métis were the result of marriages of francophones and Aboriginal women. These mixed-blood communities found their centre of gravity near present-day Winnipeg, where they lived harmoniously with Aboriginal people and Europeans. As HBC's trade increasingly emphasized the northwestern Athabasca District after 1821, and various smaller posts were shut down in the wake of HBC’s amalgamation with the North West Company, many Métis previously employed in the fur trade shifted into the provisioning trade that supplied pemmican, a food product of the buffalo hunt, to distant posts. Though Métis found success in producing pemmican, the industry was not without its problems. The 1814 Pemmican Proclamation, for instance, led to violence between Métis and the colonial administration at the Seven Oaks in 1816. Toward the end of the 19th century marked the beginning of serious decline in the buffalo herds on which the Plains economy was built.

Further west, on the Northwest Coast, the HBC also eventually emerged as the dominant partner in the fur trade following its merger with NWC. Beginning in the 1770s with Spanish arrival and accelerating after voyages by British mariners, the Pacific became the site of a vigorous trade in furs, especially sea otter pelts. As in more easterly regions, Northwest Coast groups like the Nuu-Chah-Nulth of Vancouver Island emerged as intermediaries between other First Nations and Europeans and Americans. Even after a land-based trade replaced maritime commerce in the early 19th century, the familiar pattern of economic partnership that had typified the early stages of fur commerce in more easterly areas was replicated in British Columbia.

The final Aboriginal community to come into extended contact with European newcomers was the Inuit, dwelling north of the treeline in the Arctic regions of Canada. While Viking explorers made small forays into the eastern Canadian Arctic as early as 1000 CE, and explorers — like John Davis in the 1570s — seeking the Northwest Passage contacted the Inuit as well, prolonged exposure to Europeans began in the 19th-century whaling trade. By the middle of the 20th century most Inuit had become integrated into the federal government's administrative services, with varying results.

New Euro-Canadian Imperatives

Beginning as early as the 1770s in Maritime Canada, the arrival of increasing numbers of Europeans whose purpose in the New World was farming or mining dramatically altered the nature of relations with Indigenous populations. Whereas the fur trade, military alliance and even evangelism had required co-operation between Aboriginal people and newcomers, the shift to farming and mining made them competitors in the eyes of settlers. First Nations people, especially the majority who lived by hunting-gathering, were viewed as obstacles to European economic objectives; extensive Aboriginal use of arable lands was seen as a barrier to economic development. The consequence of this change was a shift by the newcomers to policies that aimed at the dispossession and removal of the First Nations from the territories the strangers coveted. In practice these new Euro-Canadian imperatives translated as land-surrender treaties and policies of attempted assimilation and control.

Treaty-making, founded on the Royal Proclamation and other agreements, and developed in Upper Canada in the first half of the 19th century, had its fullest application in the western interior after Confederation. Between 1871 and 1877 Canada negotiated seven agreements, the "numbered treaties," covering a region from the Lake of the Woods to the Rocky Mountains, and from the international border to a line halfway up the prairie provinces. Although not all Aboriginal groups wanted to negotiate treaties, a majority of them, particularly the Plains nations, saw treaties as a less repugnant alternative to war and starvation. What pushed most western groups to make treaty was the awareness that the buffalo on whom they depended were rapidly dwindling in number while the population of settlers and farmers was increasing. Western chiefs saw treaties as means of establishing a formal link with the newcomers through the Crown, a relationship from which they could draw assistance in an era of transition. These objectives explain why it was chiefs and First Nations negotiators, not government representatives, who insisted that the numbered treaties provide farming implements and schooling.

The transition from military and commercial alliances to struggles for autonomy and self-determination was difficult for many Indigenous communities. Though many of the treaties of the late 19th century appeared to prepare communities for transition, in practice, the relations between Aboriginal people and the state post-Confederation were far more complicated and destructive.
