I can give you my opinion, and then Alain can give you more details.
One of the slides shows all possible sources of employees. Immigration is one of the major sources. However, if people who reach retirement age remain on the labour market, or if we can increase employment among aboriginal people or disabled persons, those latter groups will constitute possible sources of workers. Of course, emerging economies, as you call them, are competing for talented and skilled employees. I believe that Canada has a great deal to offer immigrants, but if their countries of origin also have a great deal to offer, we will find ourselves competing on the labour market for the best and most talented employees.
