Answer:
Much of that growth was taking place not in the actual cities but in their neighbouring municipalities. It is worth noting that there have been several resource extraction towns founded in the last 100 years but no new cities. The late 19th century saw the birth of every major city in western Canada (apart from slightly older Victoria and New Westminster), but the only truly new centres in the 20th century are satellites and suburbs of the largest metropolises. Mississauga, Brampton, Surrey, Laval, Markham, Vaughan, and Burnaby are examples drawn from the largest 20 cities in Canada, none of which contained more than a few thousand in 1914, all of which are very near or past the quarter-million mark now. Each of these began as peripheral, spillover, bedroom communities associated with a larger urban centre and, in that respect, they were very typical.
