The problem with just "living by the graph" is that it ignores whether the country has the capacity to provide basics like food, clothing, shelter, and employment to the population. You need to have both to have the working-age population be able to engage productively in the economy.

The problem Canada created is that it tried to reset it's population graph without ensuring that there was an adequate supply of said basics, and in many instances (housing, food prices) had policies that actively undermined what needed to a happen to support a rapidly expanding population. JT and the other liberal leadership read the Century Initiative and all they took away as "we need 100m people!" (https://en.wikipedia.org/wiki/Century_Initiative)

It's not that a country couldn't theoretically be successful resetting their population graph through immigration, but that they would also have to do things that would cause housing prices to fall or more competition (ie less corporate profits) in the other sectors to absorb the extra demand generated -- 2 things Canada has been absolutely unwilling to do in any meaningful until late last year.

Yeah there has been a pretty definitive drop in overall productivity in Canada since the sudden increase in population.

I believe the economic term is population trap, where your society / economy can't expand fast enough to make efficient use of the addition in capital.

It is pretty clear based on the constantly decreasing GDP per capita.
