The population has increased because Trudeau has brought in more than 1 million 40-year-olds per year in recent years.
But in terms of births, USA still has 10 times more births and a higher fertility index (1.6 vs 1.2)
Anyway, I don't see the connection. If your guys don't play hockey, it won't raise the level.
I gave you a statistical census as it is, observing a 20% drop in the ratio of Canadian players in the NHL in 27 years and a 9% drop in 9 years.
What's funny is that in the 2000s when I talked about the fact that Canadians would become a minority in the NHL in the next decade, I had the same kind of reaction of denial. Yet it happened. There I tell you, that Canadians will become less than 1/3 in the next decade.
