Good luck! Make sure that the couriers (any) don't touch the package. If they do, they'll charge all forms of bogus 'cross-border' charges such as 'import fees', 'sales taxes' etc, where no such duties or taxes exist, and hold your package ransom until you pay up (on some insecure sketchy website) in advance.
So for example you'll be charged a 'sales tax' on bike parts where these are exempt from provincial sales taxes. Try and fight this? Ha. Or you'll get charged at the highest possible rate of duties on any item in your package (such as a pair of socks) across the entire package content. Plus extortionist 'brokerage' fees.
Do the couriers submit this the appropriate share of this windfall to the federal and provincial tax authorities? Good question....
