No problem with CFTO virtual channel 9 on rf channel 8, a VHF frequency in Richmond Hill. If you are using an outdoor antenna and pre-amp, the pre-amp has to pass VHF signals. Possible issues, the VHF part has gone defective or hi-rise condo is blocking you. Suggest try just a piece of wire for antenna and see if CFTO comes in.

I am losing channels here from the south, new condos blocking the path :-(
