Another example, he has 2 Global:
real channel 27, CIII-DT
real channel 2, CIII-TV

Antennas for channel 2 are very large, because it is the lowest VHF-Low frequency.
Channel 2 is 54 to 60 MHz, center frequency 57 MHz. A simple dipole antenna for channel 2 would be 5540/57 = 97.2 inches or about 8.1 feet long.

The above antennas also receive VHF-High and UHF.

Does he really need both?

For CTV the only one that is strong enough is CJOH-TV on real channel 6, which is so strong that he could probably receive it with an indoor rabbit ears antenna or folded dipole antenna.
5540/85 = 65 inches, See Attachment

So, now we have it down to this for the locals:
For CTV, CJOH-TV, real channel 6, an indoor or attic antenna
For TVO, CICO-DT, real channel 26, a DB4E in the attic or an RCA ANT751 outside aimed at 45 degrees magnetic
For GTN and CBC, CIII-DT real channel 27, and CKWS-DT real channel 30, a DB4E outside aimed at 270 degrees magnetic. A preamp might be needed for this antenna.
You can combine the CTV antenna with the TVO antenna with a UVSJ. You might be able to combine the two UHF antennas with a splitter in reverse.

I can't guarantee that this will work, but it is my best guess based on my experience, your tvfool report, and what you have told us.
