From a demographic point of view, four major urban regions continue to emerge, and they account for a large and growing proportion of the nation's population. These regions are: Ontario's extended Golden Horseshoe; Montréal and adjacent region; British Columbia's Lower Mainland and southern Vancouver Island; and the Calgary-Edmonton corridor2.
In 2001, about 15.3 million people lived in these four regions, a 7.6% increase from 1996 compared with a 0.5% gain in the rest of the country. These four regions accounted for 51% of the nation's population, compared to 49% in 1996 and approximately 41% in 1971.
2The designation of these regions is based on clustered patterns of demographic growth observed between 1996 and 2001. The metropolitan areas of Ottawa - Hull (with over one million people in 2001), Windsor, and Halifax also experienced significant population growth during this period.
