We routinely ship to Canada by USPS International First Class Mail and USPS International Priority Mail. Priority Mail is faster and includes a tracking number, but is more expensive. First Class International can take 10-15 business days. To find out how much it will cost to ship your product to Canada, place the item in you shopping cart, enter the shipping address and select the desired shipping method. If your product is marked as free shipping (in the US), we will deduct what it costs us to ship in the US from your order when we capture the order (your credit card is not charged until we ship). That way you only pay the difference between the cost of shipping it in the US and shipping it to Canada.
If the item is of US or Mexico origin, then there is no import duty. Most products shipped to Canada are subject to GST (Goods and Service Tax) of 5% and then a Province or Territories bringing the total rate to around 12-13% (this varies). These taxes are collected by Canada Post upon delivery who then also charge a $9.95 handling fee.
