You can plug in your info and see what stations you should be able to get from various directions.
You should be able to p/u all Erie, PA OTA TV channels as I do in Toronto for Buffalo, NY OTA TV channels, as long as the Erie, PA OTA transmitters have a proper height and/or power to reach the north side of Lake Ontario.
And as for OTA Toronto channels, all their transmitters are located on top of CN Tower, I think you're too far away from CN Tower BUT London, Ontario is pretty close to you, right? The only difference btwn Toronto channels and London channels are the local news only.
