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.
Does not apply to startups, it only applies if you have +50 employees https://www.oqlf.gouv.qc.ca/francisation/entreprises/entrepr...
