What you refer to as "West Canada" was actually "Canada West" (there is a difference) from roughly between the War of 1812 and the birth of the Dominion of Canada in 1867 (nation of Canada). It started off being known as Upper Canada (meaning 'up the St Lawrence River' which flows from north to south from Lower Canada, or Québec), and after Canadian Confederation in 1867 this area was known as Ontario. Today it has a population of over 12 million people and is the single largest province in Canada - about 40% of the total population). The capital city of Toronto (first named York when it was founded in 1795) had a population in 1940 of about 600,000; today it is heading for 5 million.
I have commented on "Razee" in another posting of today's date.
