I think it's the same for all canadians,we dont seem to be able to choose our own carrier,when we choose USPS,we dont have any choice but to bear with canadian post because once the package arrives at the border,Canada post takes charge of it till it reaches destination in Canada.And right now it's a pain in the *** because Canada post employees are using desruptive tactics to force the government to accept their conditions and demands,this means our packages gets lost our become uterly late.
