Out of NBC, CBS, ABC, Fox, CW, PBS, the only one that is reliable is PBS, with WNPI and WCFE. CBS and Fox, we're waiting for a re-transmitter to go up within a few days in Potsdam, NY. Otherwise, you might not get anymore channels. ION, none.
Ottawa has the most OTA local stations (with English and French stations), but not much as far as US stations.
Your results may vary, but alas not by much (unless he was to be elsewhere in town, on the 10th floor of a high-rise!). I suggest you check out tvfool.com and similar sites.

Bell, French packages, pls! Long live OTA!
