The Maritimes need to figure something out.
Their young people are leaving in droves for Alberta and The West.
The unemployment rate in the Maritimes is the highest in the nation.
Generally the Martimes need to join all together into 1 province which would make them a greater force and could possibly help all the people living there.
And then you can have subsections within it, like you suggest:
The regions of:
Newfoundland
Labrador
French New Brunswick
English New Brunswick
Nova Scotia
Cape Breton Island
PEI
all within in the provinve of "Maritimes"
