I just sent the FedEx return lable to Canada along with my passport for them to ship it back
The tricky part is to create a return lable by FedEx as I spent 2 hrs in FedEx Centre to figure out how it can be done.
The process becomes complicated a when you select FROM address of Canada it doesn’t allow you pay by a US credit card, seems wired but I had this checked at 2 stores and numerous FedEx employees it is restriction in there systems.
So hence a work around ,create a FedEx online account and add your credit card to this account. Now go to any fedex store and on their self help computer login to your Account and create a return shipping lable with custom value of 1$, you can select any shipping method from express to ground, now use your Account as a mode of payment it allows you to. Willa!! It allows a US credit card that seems a little weird but seems to hack in their systems, now print this lable for free from there and add it with your documents and do a normal shipping to Canada
Hope this helps as it took me sometime to figure is out so thought might help someone
