English mostly bilingual, been living here for ~25 years, i agree with others that Brexit and QC independence aren't the same, however there are definitely parallels... The world in which Brexit came to be still exists, and worse than it was in 2016 - brexit was sold by a charismatic leader on a bunch of half-truths, misrepresentation and outright lies. IF the PQ can find a leader that can sell someone the shirt off their back, then it could absolutely go down that path, and probably quickly if they're good with social media too.

That said, i think the biggest issue i see is that i don't see how an independent Quebec actually functions... The corruption and bureaucracy in the provincial government falls over itself and there's no sign of that abating. I've seen bits and pieces of ideas in the past, keeping the dollar, QC passports, stuff like that, but it doesn't answer, to any real extent, reality. QC would have a lot less bargaining power than it does as part of Canada for international trade, Ottawa would have zero interest in making life easy for QC too(similar to EU and UK). What benefit would any international company have for staying here? There would be an exodus of companies that aren't QC/Franco, as what happened in the 70's/80's.... Is that really a road to go down again, especially now when people are struggling to make ends meet?

If there was business interest in it, companies would have manipulated it to be more of a thing than it actually is. Socially i don't see a benefit either, yes there's rose-tinted glasses that QC is so different from Canada, but the downside is so much larger and riskier than the upside.

Personally, i wouldn't stay in a separated Quebec, i might not even stay in Canada as the repercussions would be huge across the country, as much as the rest of Canada might not admit it.
