I think the first possibility is in public awareness. If governments issue supply chain warnings, as was done by the United Kingdom and the United States when both governments issued specific supply chain warnings to their companies or to companies in general, that has a big impact. I feel that is one thing that governments absolutely must do. They must raise awareness and name things by their name.
The second aspect is legal. In the United States, the CBP can block shipments that are even suspected of forced labour. The burden of proof is on the importing company. In the United Kingdom, there is an anti-slavery act that can be used. That's being challenged. The government can be sued to enforce it, although it really has not been very keen to actually enforce it.
I'm not aware of the legal situation in Canada, but I believe any legal possibilities should absolutely be exploited. If they do not exist, I think it would be high time to consider relevant legislation and to introduce relevant legislation that does target forced labour in the supply chains of companies that do business in Canada.
