@Mialonde1977 The charges for anything other than 99.99% silver or gold is taxes applicable - HST in Ontario, PST and GST depending on your province.
As for UPS, if they come to your door, and request a brokerage fee, you can decline it, and explain to them that YOU will clear it with customs later. It is convenient for me, as the Cdn Customs at Bridge to the USA is only 10 minutes away. Keep in mind, they will put up a fight, but it is your right to refuse their fees if you didn't request them to do it for you.
