There are some really clear examples of this. I'd say first that the United Nations is clear that companies are required to respect human rights around the world and that Canada has international human rights obligations to make sure that third party actors, including companies, respect human rights.
At the same time, Canada is entirely in a position to be able to regulate. One example I would give is the case of Nevsun Resources, which is operating in Eritrea. Sometimes there are difficult decisions that need to be made. This is a case that went to the Supreme Court of Canada. The Canadian mining company was obliged, in order to operate in Eritrea, to use slave labour, conscripted labour. If they had done any due diligence, they would have known that.
In some circumstances, companies will need to decide that if you cannot operate in a way that respects basic human rights, maybe you can't operate there, but there are many circumstances in which companies do have a really strong amount of power and leverage to be able to ensure rights are respected, and the notion that it is simply problems with other countries doesn't bear fruit. I would point to another court case—
