Final answer:
Nunavut has the highest percentage of First Peoples, with 85 percent of its population being Inuit.
Step-by-step explanation:
The Canadian province with the highest percentage of First Peoples, which includes First Nations, Inuit, and Métis, is Nunavut. In Nunavut, 85 percent of the population is Inuit. This contrasts with other areas such as the Northwest Territories, where just over half of the population are First Nations people, but the total population is much smaller. It's essential to recognize that the First Peoples of Canada are comprised of diverse groups with distinct histories, languages, and cultures. Canada's native population makes up less than 4 percent of the country's total population but represents a great deal of this cultural and linguistic diversity.
