I've looked at the service CIBC is offering, and I don't really see any advantage. As someone who's worked in Banking for a while, it doesn't really give you anything better than whatever you may currently have. I know it's not beneficial to switch from my RBC account to this.
As far as what may appeal to military members, the national access part means you wouldn't have a home branch...I know all my statements still say "Oromocto RBC" because that's where I started. This service the main branch for CIBC would be yours..
The only thing that might be of interest to military members is the possibility of transferring your mortgage elsewhere...I'm not sure how they'd do it, and as I don't have a mortgage, don't particularly care.
I know I previously floated the idea of a military-aimed Credit card, but this doesn't seem to include that
