Canadian English
Charles Boberg's 2005 North American Regional Variety Survey found that English-speaking Canada encompasses 6 principal lexical regions: Western Canada, Ontario, Montreal, New Brunswick - Nova Scotia, Prince Edward Island, and Newfoundland, each separated by a lexical boundary. Lexical boundary distinction is measured on the basis of “major isoglosses,” which occur when there is greater than a 50% difference in the frequency of a linguistic variant between regional boundaries; and mean net variation between the borders of neighbouring lexical regions.
