Thank you. I'll start and my colleagues may wish to add to what I say.
If we talk about non-compliant goods at this stage, there are current measures under the Customs Act that limit the risk that goods in transit could be diverted into the Canadian market. Pursuant to the Customs Act, CBSA does customs controls on goods in transit to ensure they're not diverted into the Canadian market and that goods in transit are not a threat to Canada or in fact their international destination. During the process of transit, these goods remain under control of the CBSA from the customs office where they enter to the office where they exit, and there are various methods of customs control that are quite specific.
