At the start of this year, the Canadian Combating Counterfeit Products Act became law. With this new power, brand owners can register their trademarks and copyrights with the Canada Border Services Agency (CBSA). Basically you register with customs and when a package is inspected and the items match your intellectual property, customs will contact you to verify the package.
They can send a brand owner a sample of the package, and the details of the sender and receiver. This can also help companies that are wanting to have civil proceedings brought against counterfeiters in court.
There are no fees to register with customs. However if a brand owner wants the counterfeit goods to be destroyed, they may have to pay a fee. This part of the bill is still being developed and details are limited.
Before this bill became law, there was no legal authority for customs to seize a commercial shipment if they thought it was counterfeit.
