We have determined that the shipping address you gave us is a residential address and not a commercial/business address as determined by Canada Post and most couriers. As residential shipping is more costly, we have to ask you to pay the additional surcharge per our shipping policies when you checked out. If you prefer not to pay this additional amount you can give us a commercial address to ship to, or you can advise us to cancel and refund your order. Sorry for the inconvenience.
