Does anyone know if this is good results or not?
Those are all the DTV stations transmitted in Ottawa so I guess those results are OK. How well do you receive the analog broadcasts? That is a much better indication of how good the antenna is.
With a better antenna you might be able to pick up one of the PBS stations from the US, but from your description of the antenna you have, you won't get them with it.
My biggest concern with your antenna is that it is likely UHF only and after the Canadian analog shutdown some stations will use their analog channel number on VHF (for example CJOH plans to stay on channel 13) so you may need a different antenna at that time.
