This is a question we address every year when we publish our report on the financial sustainability of the federal and provincial governments. It's an exercise we usually do in the summer.
The last time we did this exercise, we realized that the long-term financial viability of the provinces had reached its limit. That said, some provinces were in better shape than others, notably Quebec, which was in relatively good shape. We will repeat the exercise this summer and update our data.
However, as you mention, it's clear that the determining factor for the provinces and territories is the aging of their populations, which has a very significant impact on the cost of health care services. An aging person obviously costs the health care system more. What's more, this increase is not linear: a 90-year-old person costs much more on average than a 65-year-old, for example.
