A little late to the party, but Cheektowaga just outside of Buffalo sounds like exactly where I'm at (off Cleveland Drive and Eggert Road to be exact). I have a CM 4228 (older model) mounted on my roof with no amp or pre-amp, and I get the following Canadian stations regularly:

Aimed at Toronto:

5 (20) - CBLT (CBC)
9 (9) - CFTO (CTV - 4228's can pick up VHF signals if strong enough)
19 (19) - CICA (TVO)
25 (25) - CBLFT (CBC French)
40 (40) - CJMT (Omni 2)
41 (41) - CIII (Global)
47 (47) - CFMT (Omni)
57 (44) - CITY (CityTV - this is supposed to be near impossible to get in WNY, but I haven't had a problem for years)

Aimed at Hamilton:

36 (36) - CITS (CTS, a Hamiton Independent)
42 (42) - CKVP (CTV 2, this is actually a repeater of CKVR in Barrie, ON whose antenna is located on Fonthill, ON)

Keep in mind, I have the older version of the CM 4228, which is no longer produced and tough to get. The newer version supposedly isn't as reliable.
