Yes, your TV is capable of receiving digital TV broadcasts (ATSC signals). Just be sure your TV is set to "air" or "antenna" mode rather than "cable" mode since this controls how the TV scans for signals.

ie. analog channel CBOT, 62.9 NM(dB), PWR -15.9 dBm BUT,
for the digital channel CBOT, 57.1 NM(dB), PWR -33.7 dBm
Not sure why the pwr is so different as they are coming from the same tx'er 14.5 miles away?

Power is less important than the Noise Margin (NM) numbers. The digital signal format is completely different than analog, and needs far less power to achieve the same range. Knowing the signal power is only important if you have very strong local signals and need to worry about overloading an amp or tuner.

Question: Should I have to do something different to receive the digital channels? The digital channels are completely "ghosted" with no hint of signal. I thought since my TV was a relatively new one and HDTV capable the tuner would automatically receive digital signals?

I don't know if your TV needs to be told to use "antenna" mode instead of "cable" mode for tuning. Some TVs do not make that determination automatically. Your TV does include an ATSC tuner, so that means it can receive over-the-air digital station.
Do you have an amplified antenna? If CBOT is coming in at -15.9 dBm, that is a very strong signal and will likely overload any kind of signal amplifier (built-in to an antenna or stand-alone). When you have very strong signals like this, you can't have any kind of amps in the signal path.
BTW, the Canadian analog shutdown is scheduled for completion on August 31st. Most of your analog broadcasts should go away, and a few of your digital channels may be switching their channels around. When that happens, you probably need to have your TV re-scan all the channels to get all the changes.
If you post a link to your signal report (should look something like "http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%xxxxxxxxxxxxxxxx"), we can get a better understanding of what kinds of signals you are dealing with.
