How can I improve?
Add another antenna or change the one I have for a different one with greater distance and range.

You have a difficult location for TV reception because the channels you want are in 3 different directions. The 4-bay section aimed west seems to be doing OK. The 4-bay section aimed SE isn't doing very well because there is an escarpment in that direction too, and the SE aim is wrong for CBLT in Toronto.

If your preamp gain is set for 30 dB, there is a good chance that the tuner is overloaded by CIII-DT with a signal power of -36.6 dBm, which will make the weaker channels more difficult to receive.
-36.6 dBm + 12 dB ant gain + 30 dB preamp = +5.4 dBm
