First off, you ar discribing HDTV and DTV in the Toronto area as some kind of exception rather than the norm. Almost all channels in the GTA and Buffalo are DTV and thus HDTV. The exceptions are OECA Ch 19 and CKVR in Barrie.

I live in Whitby and can get at least 80% for 21 channels.

You did not mention and there has been no mention of amplification. Did you put an amplifier on the antenna? Did you use RG6 cable from the antenna?

If you did not, then your results make total sense. Go to the source and get an amplifier. Or better still, go to Walmart and just a buy a Phillips amplified indoor antenna. Put it near a window facing the CN Tower. If you have an obstructing building in the way, raise the antenna.

As for your TV, scan it on DTV...not cable and not annologue.
