Thank you very much for the question.
To relate this to the previous discussion we had, Ms. Glover's discussion, inequality is rooted in the labour market, and the tax and transfer system is basically a bandage on top of that. What we want to build up is a high-pressure economy at the lower-end skill level. Let the demand outstrip supply, and you'll see wages rise.
In both cases, the employment insurance program and the temporary worker programs, the design of these programs in effect offers a wage subsidy to low-skilled employees. As Professor Boadway said, the evidence is not yet in on this, but I can't see how that can promote a high-skilled, high-wage economy at the low end.
