Most Torontonians wanting desi channels have one 20" elliptical for regular Sats and another one - probably a 18" dish for 61.5W for International channels.. Use a 4 to 1 DisEqC switch. If you do not have two dishes, you can get an extra dish, disEqC switch, and complete installation for as low as $110 in summer.
Whole of North America is West of longitude 61.5W, so you should be able to get the sat from an east facing balcony. However, once you cross midwest and live west of it, you can't see 61.5W - it is too far 148W, which is the other sat, can't be seen from east facing balcony from Washington state. You might also consider 121W (Echo 9) for desi channels, if that is more convenient. You might just see it from an East facing balcony from Seatle.
