You or your husband will have to pay the tax and duty on the goods. You are allowed up to a limit of personal property that are exempt (clothes, personal items, computer, etc) but for a container full of stuff purchased outside of Canada you will need to pay. Your shipping company can more than likely help you determine the cost. Also, using a company like DHL, FedEx (they have container services also) you can usually get a better deal on customs, etc then most freight forwarders and customs brokers will charge.
Can I know what happen if we have stuffs that was used, do we have to pay tax for those items? How many goods do each family allow to bring?
