I don't know why the assumption is that this hurt's Canada's ability to properly assess and tax - it's like a private whois registration, there is a registrar or stand in that can (and usually trivially accedes) to governmental requests as to original identity, it's just harder for individuals to track down. The government knows who owns what[1]. 1. At least in Canada, there are all sorts of fair accounting laws that require people handling assets to report it to the government in addition to the actual parties who own the assets to do that reporting. If your company is shifting money around in various Canadian bank accounts to launder domestically... the government knows... if you're only using international accounts then why are you even registered in Canada.
