If it's going to the hub, the address you ship to will be:
EISYYZ C/O (Buyer's Name)
2-2520 Royal Windsor Dr
Mississauga, ON L5J 0B8
There are also some indicators on order page pointing out it's EIS:
and on the order's listing page there will be a globe icon instead of a truck for EIS orders:
To see EIS as a shipping option you need to set your location to another country...for example on one of your listings I set United States, and it shows EIS. UPS is cheaper so it shows your UPS option first.
