Humdum, You can't unless someone in canada will sub for you or share sub with you. Secondly, It is really depends if you really getting the signal. It highly unlikly unless you live close (within 200 hundered miles) to the Canadian border.
I live 15 miles outside NJ border I get signal level of 70% to 75% with a 20" dish on either 82/91
If yo have a relative or a friend live in Canada I guess yo can share the bill and get B#V or S#C
B#V has better movie channels But yo won't get local channels in NJ
3 to 5 years from now IPTV will let yo go anywhere with an IPTV set top box to take anywhere using internet instead of satellites At least that's what I sense from satellite trade shows
