Importing Jewelry Supplies to Canada

I will be touring in Europe for a little while. the plan as usual is
to visit some jewellery supply. I wander if anyone has experience on
how it works with taxes. Do I have to pay taxes there as well or just
here when I return to Canada? If I pay taxes there can I have them
refounded and where? If I don’t pay taxes there will I still have a
invoice to show at the border? Thanks to all the entusiastic reply!
