Property that is never returned gets sold, unless selling it would cost more than it is worth, in which case it is destroyed. Nothing can be sold or destroyed within 15 days of the notice refusing to return it, or while a Canadian court case about the seizure is still running. Documents are treated differently: they are kept as long as administering Canadian law requires, then returned to the authority that issued them or disposed of under Canadian law.
(1)If a thing seized, other than a document, is not returned to its lawful owner or the person from whom it was seized, the thing shall be sold unless the costs of the sale would exceed the monetary value of the thing, in which case the thing shall be destroyed.
(2)A thing seized shall not be sold or destroyed (a)within the 15 days after the day on which the notification of a decision not to return it was provided; or (b)before a final decision is made in any judicial proceeding in Canada affecting the seizure or the return of the thing seized.
(3)If a document is not returned to its lawful owner or the person from whom it was seized, the document shall be held for as long as is necessary for the administration of the laws of Canada, after which it shall either be returned to the authority that issued it or disposed of in accordance with the laws of Canada.
