Hmm. I know it's illegal to prevent someone from putting up an antenna in the US (even on condos or apartments), but I guess that law might not cross over to Canada.

You MIGHT do better with a more "traditional" antenna with a separate higher quality / higher db preamp.

I'm pretty sure City's signal is shaped to send most of it to the north/east/west, so there might not be much hope of receiving it where you are - although SOME Buffalonians (with big antennas) have reported getting it.
