In the language there's often no differentiation between sex and labour, so I certainly think the bill would affect both equally.
What I don't have any information on is whether there is also domestic trafficking in labour of Canadians or permanent residents, for example, from northern communities or “reserves”, as we call them. But certainly that's a potential problem.
From a female point of view, the Canadian Women's Foundation has struck a national task force to look specifically at the issue as it relates to aboriginal women being taken from their culture for sex. But from a domestic labour perspective, I can't help.
