Keep in mind, you can not store a vacation trailer in Canada during the off-season. Customs will require a copy of a work order from the establishment handling the repairs. This work order must contain a description of the article, owner's name and address, type of work to be done and the time and location at which the work will be effected. You are allowed up to 44 pounds of meat products. Any gasoline or oil imported, beyond the normal capacity of your vehicle, is dutiable.
Additional quantities are subject to duty and tax.
All fireworks need authorization to be imported into Canada. Duty-free means you won't be taxed on the items. GST stands for Goods and Services Tax. When you enter Canada, you'll be given information on the GST visitor rebate. Fully automatic firearms and handguns are prohibited.
