It is sustainable, just not with the current polices. At its current first world standards, Canada should be able to attract top talent from any developing country. It has practically infinite space & resources. They can selectively import a mix of medicine, education and construction professionals to make sure that services keep in touch with the rising population. Sadly, their polices are all over the place. While the US skims from the top of the Indian talent pool, Canada seems hell bent on importing the most mediocre of Indian talent. This article does a good job of elaborating on the needles and massive hurdles faced by a foreign health-care professional, if they want to immigrate to Canada. You can complain about the shortcomings all you want, but the unwillingness to expand slots is a purely political decision. Similarly, despite having a massive housing shortage, housing remains firmly in the grasp of Canadian NIMBYs. All social-welfarist countries will need to find ways to replace their aging workforces. Some will try to promote fertility (Hungary, Poland?) and others will try immigration. There isn't much else you can do. For once, the US had had a mature and well thought out legal immigration system. It pretty much selects for only those who can productively contribute to the economy, and that's after drawing ~$200k in tuition and ~5-10 years of uncompensated social security taxes.
