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.
