Sorry for the delay in response.
(1) If WBXZ-LP's move away from

is because of WNYO's move to

,
then wouldn't CHCH-DT

have the same concern with CITS-DT's move to RF
?(2) I understand the concerns with (low) VHF, but WNYB-DT is moving to

next year with increase ERP which will give it a stronger pattern in Southern Ontario. I think if WBXZ-LP moved to

with a vast increase in power, it could go non-directional. I think he's missing a big opportunity by not reaching Southern Ontario.
