Canadian English (CanE, CE, en-CA) is the set of varieties of the English language native to Canada. According to the 2016 census, English was the first language of more than 19.4 million Canadians or 58.1% of the total population; the remainder of the population were native speakers of Canadian French (20.8%) or other languages (21.1%). A larger number, 28 million people, reported using English as their dominant language. Of Canadians outside the province of Quebec, 82% reported speaking English natively, but within Quebec the figure was just 7.5% as most of its residents are native speakers of Canadian French.

Canadian English contains major elements of both British and American English, as well as some uniquely Canadian characteristics. While Canadian English tends to be closer to American English in most regards, the precise influence of American English, British English and other sources on Canadian English varieties has been the ongoing focus of systematic studies since the 1950s.

Standard Canadian English varies only slightly from Central Canada to British Columbia, an area that includes the northern territories, but excludes the notably different accents found in the Atlantic provinces. Among Canadians living in central and western Canada, a more distinguishable accent difference is heard between those who live in urban centres versus those living in rural settings. Though western Canada was largely populated by farmers from Central and Eastern Europe in the early 20th century, the vast-majority of native English speakers were re-settlers from Ontario and Quebec; these already-established Canadians were of mostly British, Irish and American Loyalist descent, who took advantage of the Dominion Lands Act, which encouraged the initial settlement of the Canadian Prairies. This linguistic homogenization was further compounded by households accessing both Canadian and American media from coast to coast to coast, including the advent of the radio, and later, the television.

Phonologically, Canadian and American English are classified together as North American English, emphasizing the fact that the vast majority of outsiders, even other native English speakers, cannot distinguish the typical accents of the two countries by sound alone. Canadians and Americans themselves sometimes have trouble differentiating their own two accents, particularly when someone speaks with an urban Standard Canadian English accent, one that often sounds similar to Western American English. There is also evidence that Standard Canadian English and some Western American English (Pacific Northwest and California English, for example) are undergoing a very similar vowel shift, since the 1980s.
