We've gotten a DIRECT TV signal on Vancouver Island in the west and on PEI and Nova Scotia in the east, as well as points in betweeen.
With Direct TV (Possibly with DISH as well) if you cannot get HD signals, try "All Channels" on your Preferences. The non-HD signal is not as picky. That also works during bad weather.
Many RV parks, including those in Canada list the proper settings for satellite.
