Keegan here from One Star Leather. Let me know if you have any questions! I'll try to check back here daily while this is posted. You can see colors and get more information @ www.onestarleathergoods.com Thanks!
Patrick@Patrick Honestly, I've never tried Canadian bills in this wallet, but you should be able to figure that out if you compare dimensions.
@Robert Here is a link to the interior colors (wallets can also be fully these colors). http://onestarleathergoods.tumblr.com/post/52318255643 I have not had an opportunity to make swatches for the listed exterior colors, but if you scroll through my website you'll see examples of all the colors available. If you have specific questions, please don't hesitate to email me: info@onestarleathergoods.com

I just took a picture of the wallet with Canadian bills inserted on both side of the pockets for your reference. Admittedly, it doesn't fit as well as US bills, since Canadian bills are slightly taller, but the wallet still works great, and has no problem folding despite tighter clearance.
