Looking at your report, it seems pointless to chase the US stations from your location. The complicating issue you have is the orientation of the two towers carrying Canadian broadcasts, about 100 degrees apart. Getting both with one antenna without rotating it will be challenging.
To the recommendations: both antennas are UHF bow-tie arrays, not yagis, and both have way too narrow beamwidths to work in a fixed location (meaning that pointing the antenna to get one tower will put the other tower in one of the antenna's "blind spots"). You need an antenna that has a wide beamwidth, like the RCA ANT-751.
Before you go any further, though, I recommend signing up at the
OTA forum at digitalhome.ca. There is a subforum for reception results that will have a thread for your area. If you feel the least bit handy, folks in the antenna research and development thread at that site have come up with a very wide beamwidth antenna called the "stealth hawk" that could be the perfect design for you.
