I read it and found no meaningful references to reverse grey-market activities. What part of Canadian rules regarding reception of encrypted US DTH programming applies to the converse?
Perhaps the CRTC may try to insert themselves into a situation where the end-user is not telling the truth but I question their jurisdictional ability to prosecute non-Canadians who are paying for the service. They can certainly notify the carrier of the deception but I suspect that may be the limit of their "power".
As noted in the House of Commons Committee report on "reverse grey market", both the committee and Bell-Expressvu were active and determined to stop reverse grey market, as grey market is illegal in both countries (copyright and licensing) and, naturally, each country is responsible for prosecuting grey market violators (why would you think otherwise?). The CRTC certainly could step in at any time if a DTH satellite company actively pursued subscriptions in the other country in violation of these laws. Any CRTC warnings ignored by the DTH satellite company could very easily be remedied by simply removing their license. I suspect the FCC could do the same (whether either would take that drastic step or not, is another story, but I would suspect if flagrant enough, pressure from the opposing country, as well as from its own government, copyright holders, etc., could result in such a drastic step, if warranted).
