If what you are doing is getting the Bloc pissed, it is likely good for Canada. If Quebec was to successfully separate, they would be screwing every Francophone outside of the province because interest in bilingualism will stop instantly. There will be an emotional backlash the likes this country has not seen for a long time.
Quebec then would have try to attempt to have labels printed in French for a mere 5 million people, that will be a significant cost to the economy. Also exactly who are they going to trade with, the only francophone economy worthwhile is France and the French aren’t all that keen to support their forgotten “love child” with anything more than lip service. The rest of the economies that speak French likely don’t even come close to Quebec’s GDP. If Toshiba is successful in selling their mini reactors, it could cut into the one major money maker they will have, hydro-electric.
Quebec will also have to negotiate with the First Nations and they are under no illusion about what the Quebec elite thinks of them, so that will consume huge resources and strife will be evident. To maintain peace and not to suffer breakaways they will have to sell the farm in my places, angering the Bloc supporters.
All of the immigrants coming in from Francophone countries will likely be more of a drain of resources than an resource bringer, plus they will be the wrong colour to fit in with the “real Quebecers” who will be forced to cut immigration to preserve their own majority, whom the last time I looked where not even breeding enough to replace themselves. If a majority of immigrants take over without the elitists mentality they will look at the current state of affairs and say lets join Canada on a similar level we were at before, except they will be bargaining from a position of weakness.
