If the area you want to listen to isn't covered by liveatc, you can get a scanner radio that can receive the air band. You may not hear most of the comms from ATC, that would depend on how close you are to a transmitter site, but you would be able to hear the aircraft without any trouble.
Tried that link and appears to be silence as JetScan1 said below. I only have my handheld VHF scanner, so would only be able to hear one-way aircraft traffic since i'm so far away from CYBP...if i read you correctly. Is CYBP where all the en-route traffic is handled for this area of airspace. Apologies if my terminology is incorrect, i know enough to be dangerous right now (aka VatSim)
