When I didn’t use my Business Number with CBSA for one year – is it still active ?

You have to show your import/export account on your customs documents. This applies to most shipments that enter Canada.

You only use your import/export account for importing or exporting. If you do not use it, your account will expire after two years. You can reactivate it by contacting any customs office. If there is any change in your status (e.g.,name or address change), you must report these changes to us as soon as possible.
