I cant find nor the possible manufact neither possible specs on that now old 88302B antenna. First make sure it is a high gain UHF antenna since CBC, TVO and Global from Toronto are UHF only. Your local CTV 2 on VHF is so close , you will get it anyways probably.
you mention it has a main boom and a corner reflector , sounds to be some kind of yagui or similar therefore the more elements the antenna has the higher the gain and more directional. So count the elements (not the reflector neither the dipole/s).
Second, the size of the elements tells you wether it is UHF capable or not, for UHF they are usually less than 20-30 cm long , for VHF they are longer. If the elements are long then it is probably only VHF capable and therefore you will need a new one. Also maybe it is already damaged by the wind , missing elements, too rust, in that case consider buying a new antenna, High gain , Highly directional , possibly hi VHF capable for CTV ch 9 from Toronto. (local CTV 2 has other programming).
You do need a very good preamp like the close to 100 cad channel masters. Do a tvfool.org analysys using your coordinates and 30ft antenna height and tell us the results or post a picture. We need more info for further analysys. It is also a good idea to contact a reputable local installer, be a cuban and ask around, lol, for a recomendation.
Just another option if I have not mention it before , although expensive will give you tv stations from almost every corner of the world with a motorised system.
I am not aware of CTV or Global being available via satellite C or Ku band 24x7 but all CBC and RDS timezones (5 each) are available3 via C band (requieres a 6 feet dish installed on the patio, full cost of dish only 200 cad). You will need a new HD MPEG4 DVB-S2 digital sat receiver like the cheap Openbox S10 that usually cost 130cad. Consider extra 200 cad to install and setup. This is just an option, for extra 100 cad this dish can be motorised so you will get lots of channels accross the satellite arc (close to 60 satellites)
