Very briefly, something that worked for 40 years, the temporary agricultural workers program, with very specific rules, was an agreement. We had 18,000 people come and go; that's it.
I think what you have to do is pick sectors for which there is a great need, in regions where there's a great need, and to work the compatibilities. Clearly it would be the western provinces. All of them have a serious problem of semi-skilled workers—welders, machinists, electricians. I think the three countries probably could work on that specific sector, probably linked to energy. It would be something very specific and not involve the whole country, but basically the provinces that need it most.
Eventually, for Mexico we'll be needing a lot of Canadian engineers, so it's both ways, but it's sector-specific.
The last comment I have, which is very practical, is to facilitate things for businessmen, so that for businessmen in well-known prestigious companies you facilitate the possibility of having movement of people. For example, I know that the Four Seasons hotel group would like to have Mexicans work at the middle level. They would work in Canada, in the United States, and in Mexico. It makes this very difficult.
There's a need for pilot projects, probably with specific firms that are prestigious, so that you would not have the problem that they would do something illegal.
