CanPass Air - fast immigration processing

On my weekly trips to Canada, I have recently been able to use the CanPass Air customs clearance system. This uses biometric information, iris scan, to determine my identity, then after I answer whether I have any items to declare, allows me to bypass the usual immigration lines and go straight to the customs exit. Especially when I am sitting at the back of the plane, this system is a real boon.

There is a system called Nexus, which works both ways, i.e. into the US as well as Canada, but I travel through Winnipeg and they do not have Nexus yet.
