That's a false impression, at least for Quebec. I don't know how it is in the rest of Canada, but statistics in Quebec show that 60% of those 65 and over have incomes of less than $30,000. Consequently, it's a misconception to think that 65‑year-olds are better off than 75‑year-olds, at least in Quebec.
