Actually, CARP has a full position on that. It is true that in federally regulated industries, mandatory retirement still persists. The companies can't do anything about it, but they can petition the federal government to change the law with one fell stroke, which is what all the provinces have already done. They allow people to keep working when they need to or want to, and they provide a structured retirement so that they can defer their pensions until they need it.
