Canada is projecting faster population growth because of more immigration than they have projected in the past. Previously Canada was projecting 39.4 million people in 2035 but now they are projecting a medium assumption forecast of 43.5 million in 2035. There will be many updated national population counts and new population forecasts starting from the end of 2010 and through 2011 and 2012 as the census results from 2010 are tabulated for different countries.
Canada would be in the range of 33 to 38th most populous country. I am expecting that over the next couple of decades that the current estimate will be revised upwards again. Canada is doing very well with oil in Alberta and Saskatchwan and natural gas in BC.
If Canada’s population growth trends go towards the high-growth scenario then the 2050 population could be 60-75 million. This would put Canada around 25th in World population and possibly exceeding the expected population of France or the UK.
