CAQ govt is working on that. Soon will come a bill which mandates all employers to exclusively recruit French. Currently the ruling govt of Québec is anti immigrant and showing signs of a future separatist referendum. I won't be counting on Québec to stay in Canada in the future.
That's a very pessimistic view of Quebec. PQ/Separatism is irrelevant and last time they were in power they got booted out quickly. It's more likely that Montreal separates from ROQ than Quebec separates from ROC.
