It finds that the working-age population would have to grow by 2.2 per cent per year through 2040 to maintain the same ratio [of pre- vs post-retirees -- to be able to pay for the health care that Canadian seniors are going to need (and, I assume, an equitable retirement stipend from the consolidated fund we've elected them to manage) ].

And if the country wanted to go back to the average old-age dependency ratio it had between 1990 and 2015, that group of Canadians would have to grow by 4.5 per cent annually.

Given inflation, yeah, 4.5% would give us a better cushion and grow the CCP fund better for for equitable benefits and improved volatility resistance down the road as, I don't know CoViD continues to shut down services (my sister's vet hospital, this week) or similar floods/fires/karens impact the fund's stability.
