Cargo flights are increasing in Halifax with FedEX, Purolator, ASL, Korean Air Cargo, CargoJet and others.
There is also increased business jet traffic and military stopovers. Halifax also handles many flight diversions for medical and mechanical emergencies.
Scanning CYHZ
The airport is far enough away from Halifax/Dartmouth proper that monitoring from home is spotty at best, although some parts in the city may be just fine. Your best bet from downtown is the Tower and Terminal frequencies. That said, experiment a bit and try getting the ATIS. It you get it, try some of the FBOs and ground support frequencies.
As always, the better the antenna the more you'll hear.
Here's a list of important frequencies at CYHZ. There are presumably other frequencies not included here such as law enforcement, fire, security and Canada and US Customs. Some may be on the provincial TMR II system or unpublished.
