Raising the antenna height did not help with the American stations. For the Canada stations I recommend a Winegard HD1080 antenna aimed at about 343 Degree magnetic compass.

The angle of reception from the antenna to the Tv stations to the north and a little east and the Tv stations that are to the east and a little south is a very steep angle. However I think the stations will be received. If not then I suggest 2 antennas , one aimed at the stations to the north and a little east and one aimed at the stations to the east and a little south. The 2 separate antennas would not be connected together on the same coax. Separate coax would be run to each Tv. One antenna would have a 2 way splitter and the other antenna would have a 2 way splitter , the coaxes from the out puts of the splitters would go to each Tv. And a remote control A/B antenna switch would be at each Tv. You can also Google all the stations call signs and see if all the channels you will like to watch can be received by pointing one antenna at one group of stations.
