I don't think you will have any problems. However, expect delays in customs. It can take them a while to get it through.
I ship parts to canada quite often and typically only takes a day or so longer then packages being shipped stateside. Boils down to the shipper have the proper documentation and invoices filled out when shipping. I highly suggest UPS. Their internet shipping programs is very user friendly and all documents print right off.
To be honest I never shipped to canada using UPS, I've shipped using USPS a few times and always had trouble.
Heres a great Idea that I learned from a guy I bought a bow from in Ireland... He took the bow apart and sent it broken down so the box was the size of a lop-sided pizza box, it took about 8 days if I remember right, and on the box because of the anti's he wrote sporting goods.....worked like a charm..... Caution this only works if you have a way of putting the bow back together!!!! (ie. bowpress) :laugh: :laugh:
