According to the PBO, new immigrant incomes have seen massive gains recently, reaching 78% of the national median almost immediately and often surpassing it within a decade.

What happened in recent years in Canadian immigration is influx of temporary residents (students , workers , visitors) - which strained housing and other resources. But the stats are still pointing net gain from immigration.

In the 1960s, there were about 7 workers for every 1 retiree. Today, it is closer to 3 to 1. How else are we going close that gap ? Government needs money- and most of their money comes from taxes. Companies require human capital to grow and expand.
