There are two answers to your question. One is that for those categories of professionals, there are prevailing wage requirements. In other words those professionals coming from abroad into Canada would have to be paid the prevailing wage in Canada, in that region, for a professional at that level of expertise and experience.
Therefore, if what you're suggesting is that maybe the company would be more inclined to hire this worker from abroad than our young people, then they would be hiring them at a higher wage. They would have to hire them at the same wage they would pay for the more experienced Canadian professional, given the prevailing wage requirements.
They would also have to have a pre-arranged contract. They don't come in and look for a job. There would have to be an investor or a contract here that requires that person to come in on a temporary basis to facilitate the particular investment or particular service that is being provided by the TPP country.
