A multitude of languages have always been spoken in Canada. Prior to Confederation, the territories that would become Canada were home to over 70 distinct languages across 12 or so language families. Today, a majority of those indigenous languages are still spoken; however, most are endangered and only about 0.6% of the Canadian population report an Indigenous language as their mother tongue. Since the establishment of the Canadian state, English and French have been the co-official languages and are, by far, the most-spoken languages in the country.

Canadian English encompasses the varieties of English used in Canada. According to the 2016 census, English was the first language of 19.4 million Canadians or 58.1% of the total population; the remainder spoke French (20.8%) or other languages (21.1%). In the Canadian province of Quebec, only 7.5% of the population are anglophone, as most of Quebec's residents are native speakers of Quebec French.
