I would say a couple of things on that.
The first is that I'd have to defer largely to the Canada Border Services Agency, which is the group responsible for enforcing the ban.
What I would say around the general idea of a region-wide ban is that part of the challenge is that Canada Border Services Agency interdicts goods on a shipment-by-shipment basis, but the larger challenge is that shipments that are coming into Canada, as I noted at the outset, tend to be labelled by country of origin and not by region of origin. There are also, as I said at the outset, challenges around complexity of supply chains, such that you could have cotton, for example, that is emanating out of Xinjiang but that makes its way through supply chains in four or five different countries before the final product comes into Canada.
There can be challenges for any organization or government agency in being able to determine where exactly different components of a particular product came from. This is part of the challenge that needs to be thought through and worked out, with government and industry working in collaboration to figure out how they can have a better depth of sight into supply chains to ensure that they can be cleaned adequately.
