I think, to answer your question, the chasm that I referenced is the amount of money being paid by the services and the amount of money being received by the artists. You referenced the possibility of foreign services established elsewhere and if there's a possibility for them to steal the content and to broadcast it back into Canada. Technically, that is possible. But those companies, like those anywhere else, could potentially face copyright infringement.
There are a lot of services available in Canada today that broadcast from the U.S. and don't pay royalties in Canada. It still exists.
