Yes this do, and almost did, failed by 1 or 2 votes... I lived in Montreal "Quebec" for a couple of years the things you see and listen to about this issue... for instance on Canada day i remember seeing a couple of 30 something looking hill billy looking fellas in a huge 4x4 car with Quebec flag all over and dragging a big Canada flag on the floor behind, all dirty and torn.. in the middle Canada day street parades.. which are lively in that city due to foreigners impact.
Nothing is worse than the Quebecois hicks who have the Quebec flag next to a Confederate flag on their trucks.
Most people in Quebec don't want independence though, the number if hard nationalists has went down since the last referendum. Of course thanks to Harper that balance is shifting a bit, but the PQ election was more about opposition to the Liberals incompetence/corruption, tuition hikes, and the far right shift of the rest of Canada than it is about separatism.
There will always be the hardliners who want to drive out everyone who isn't pure laine Quebecois and ban English though. Montreal is actually where most of the Canada haters are though, since it's the one place besides the Ontario border where English is heard every day leading to a hostile minority, most of the belle province is too isolated to care.
40% isn't a majority. It's also more like 35% in support, the Le Devoir poll had a political agenda.
Anyway an independent Quebec would be a complete and total disaster, even if I understand the feeling more and more. Canada is increasingly getting ruled by Western Canada, and Western Canadians tend to not understand and hate Quebec.
