I think wage analysis would most likely fall under Employment and Social Development.
We monitor wages quite carefully. We track wages for hundreds of different occupations and do so for each occupation in many regions across the country, and these are posted. These form the basis for the way we process the application, so that the employer has to pay above the prevailing wage in a given occupation.
We also use the wage to determine whether it's a low wage and is processed in the low wage stream with an extra set of worker protections or whether it's processed in the high wage stream. The wage analysis we do is very important for setting a credible prevailing wage.
As for wage suppression, it's a hard question to get a definitive answer to. There was a little bit of analysis done in the context of the dramatic increase of temporary foreign workers in Alberta during the oil boom, and there was some evidence, including some by outside commentators, of wage suppression in that instance. That's about the only example I can point to in which we've discovered this with some degree of certainty.
