Let me clarify my question.
In fact, I already know everything you have said. What I want you to clarify for me is why this requirement only applies to ships docking at ports that are not ports of entry.
Are railway companies subject to the same requirement to scan the contents of rail cars arriving in Canada from abroad?
Let’s take the example of a shipment of cars filled with drugs from Mexico transiting through the United States to Canada. Does that mean that the contents of rail cars arriving from international destinations have not been scanned?
