Quebec can't join the US - they can't even read the Constitution.
Atlantic Canada is only a basket case because of the Canadian federalist society...they'd thrive in the US with all their resources and without the endless corporate welfare...they are right now pawns of the federal government in Canada.
I guess you missed the official signing between the Provinces out east and the Feds that now allow the Provinces to have much more control and increase tax wealth over their new found oil and gas wealth .....
Quebec has never signed the Canadian Charter.
