I understand what you're saying, but perhaps I worded my question poorly. I meant that, in my view, the individuals who came from Europe and, among other things, built roads in Quebec and Canada during the 1950s and 1960s met a worker shortage. At the time, Canadians could have done that work, but, for all kinds of reasons, they didn't.
The present situation can't be identical, obviously, but certain aspects can be compared. That's what I was trying to bring out. On the one hand, there are immigrant workers, and, on the other, temporary workers, but that's a result. Perhaps I'm venturing too far, I don't know, but it seems to me that, on the whole, conditions are not that different with regard to the arrival of immigrants and that of temporary workers.
