When you use the term 'separatism', it signals you do not understand quebecois nationalism.
as proposed by quebecois nationalists of yore meant a number of common institutions: security (armed forces), economy. Think European Union (EU).
The movement in favour of sovereignty association is for all practical purposes dead. Please note that the Canadian federal state made a number of initiatives to co-opt quebecois nationalism over the years.
Please note that the socio-economic factors that initially drove quebecois nationalism in the 1960s have evolved in the favour of French-speaking quebecois. They used to be near the bottom of the socio-economic pile with only southern European immigrants and indigenous peoples occupying a lower rank.
These days bilingual quebecois of French Canadian origin earn the highest incomes in the province. [edited for clarity]
The quebecois opposition to shale gas and oil pipelines is annoying but no more so than similar opposition in British Columbia and far less costly to western Canada than BC's opposition.
