There's a minor distinction under the Accord between a permanent and a temporary immigrant. In the former case, when a person receives a Quebec Selection Certificate, a QSC, it is very clear that he or she has applied for permanent residence first in Quebec, that Quebec has selected that person and that the federal government is required to offer permanent residence following security and health checks.
The vocabulary is slightly different for temporary immigrants. They're required to give their consent, and that has given rise to the Quebec Acceptance Certificate, the QAC. However, what would be ideal, at least from Quebec's standpoint—it might not work in Canada—would be for the same rule to apply to both QACs and QSCs, in other words, for the study permit to follow when an individual has received a Quebec Acceptance Certificate. However, that's not currently the case.
