I know I've posted my reception capability at my location before, but someone further back in the thread was specifically asking about East of TO.
I'm in the Stouffville area. This area is great for reception of OTA DTV. Using an attic mounted UHF antenna, with a pre-amp separate from the antenna, I can receive everything and consistently stable, with the exception of WNYO-DT, that just makes my Samsung 151 blink. They are all incredibly reliable, day or night. During the summer in humid weather I had some minor issues with a few stations for very short periods of time. I know a lot of people have trouble with NBC-33 but at my location its great at a solid 8 bars 99.9 percent of the time. I also get WXXI-DT on most days in June and July, and the other Rochesters are rare, but I have received them from time to time, since they are all at low power. I do not get 15-1, only an analog religious station, but 66-1 comes in fine, and the newly testing CBC channels are both at 9 bars.
