The CRTC requires Bell to resell its lines for fixed rates. Bell must offer service that's at least as good as what it provides to its own customers. As the regulated rate is below Bell's own rate of return from an actual Bell customer, Bell has no incentive to provide better service that what it provides to its own customers. If the CRTC allowed for other arrangements, Bell could strike a deal with a wholesaler to offer unlimited service at a higher price. As it stands, it can't. Nothing here is surprising.

If you own your network enough, you could consider multicasting. udpcast is one tool for doing this, or you could look into implementing a file carousel. If you don't have the network support for multicast, then this won't be very helpful.
