If this is a personal shipment you may bring in 20kg. If it is a commercial shipment you will require a Cheese import license which can be applied for before you start importing from the Canadian Food Inspection Agency. Secondly, cheese is regulated and a import permit is also required in order to benefit from a lower duty rate. If you do not have a import permit the duty rate for cheese will be over 200%. Permits are obtained from Global Affairs Canada based on a quota. Do not import cheese until you know you have these licenses and permits in place or you may pay large duty amounts.
