It would be disastrous for all of Canada, Quebec as well. Large parts of the world depend on a fairly recent phenomenon (TOURIST DOLLARS). I am afraid that many in the Maritimes, Ontario and most of the western provinces would simply not consider Quebec as a tourist destinationanymore and the loss of revenue from this source would be substantial. I have visited Quebec annually since 1997 and will be there again this year in mid July, so I hope that this beautiful province does not separate as in the long run it will be Quebec and Quebecers that suffer.
I have lately felt a strong resentment of Quebecers from people from other provinces, especially in the west, where it is felt that Quebec holds the rest of the country hostage with this seperatist threat. Many times lately I have overheard people state " F..... them, let them go, we do not need them and the air of uncertainty that comes along with Quebec. If they want to leave, open the door, let them out, close the door and turn out the lights.
I know that Canada as we know it would never be the same.
