I heard that companies are mandated to support bilingualism because of Bill 101, which could be a challenge for startups. But then again, perhaps that can be easily overcome by investing enough in localization.
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.
