Actually, I think that making more small provinces is the worst possible choice ... all that accomplishes is to make the federal government more intrusive by making it "needed" to effect fiscal redistribution. We would do better to have five larger provinces:
1. Pacific Canada (BC + YU: population 4.7 million);
2. The Prairies (AB + SK + MB + NT + NU: 6.6 million);
3. Ontario (13.6 million);
4. Quebec (8.2 million); and
5. Atlantic Canada (NS + NB + NL + PE: population 2.4 million).
Or we might have, my preference, just three:
A. Canada West (population 11.3 million);
B. Central Canada (population 13.6 million; and
C. Canada East, a bilingual province with a distinctively French flair, population 10.6 million).
The three province solution would, I think, improve productivity and intra-national trade and commerce thereby improving our overall prosperity and it would render the national, central government less "necessary" and, therefore, cause parts of it (powers) to migrate back where they belong (constitutionally) and it would, eventually, grow smaller and cheaper to operate and, thereby again, better focused on its core responsibilities.
