RonnCanadian bills are pretty close in height to USD. I don't have a CAD bill but it would definitely be tight, so the top edge would get rumpled if you close the wallet tightly. It's still definitely viable to fit CAD bills.

ChristopherJThanks for the picture Chris. Can anyone with Canadian Bills chime in on this? I really want this wallet but don't wanna be disappointed with beautiful wallet that is too small. Thanks
