Based on the figures posted above, half of Canadian population increase is happening inside GGH (about 360k and 180k, respectively). As Canadian natural growth (births minus deaths) keeps sinking like a stone, 125k in 2014 to 85k in 2019, set to disappear by early 2030's, and then go into negative terrain, only increasing immigration will keep things afloat.

GGH will be under the same dinamics affecting Canada overall but it might face more competition from other metro areas. It's challenging to keep the current dominance indefinitely (half of country's population increase for less than a 1/3 of population).
