Regional Variation
Canada has very little dialect diversity compared to the United States. The provinces east of Ontario show the largest dialect diversity. Northern Canada is, according to William Labov, a dialect region in formation, and a homogeneous dialect has not yet formed. A very homogeneous dialect exists in Western and Central Canada, a situation that is similar to that of the Western United States. Labov identifies an inland region that concentrates all of the defining features of the dialect centred on the Prairies, with periphery areas with more variable patterns including the metropolitan areas of Vancouver and Toronto. This dialect forms a dialect continuum with the far Western United States, however it is sharply differentiated from the Inland Northern United States. This is a result of the relatively recent phenomenon known as the Northern cities vowel shift; see below.
