A fairly soft approach is to require reporting on how they conduct the due diligence on their supply chains, how they report that, what was it, and did they find linkages to Xinjiang. There could be just a pure transparency requirement, and that alone may have an influence, because those companies won't want to say that they found Xinjiang buried in their supply chain. In the U.S. we have the Tariff Act, and that can be used to seize goods produced anywhere in the supply chain with forced labour. In the U.S. that is a pretty powerful tool. I'm not aware of Canada having the same tool, but I was suggesting that, in general, given your government's strong stance against forced labour, it might be worth considering a measure like that.
Those would be some of the ways you could at least start to impose extrication on companies, and you could ratchet it up from there if they're not responding.
