We can't predict the unpredictable... but if the trend continues, the demographic weight of Québec within Canada will pursue its slow decline. In 2050, Québec should account for ~21,5% of our country's population, with ~10,87 M inhabitants. It the commuting patterns towards the main cities continue to grow, Montréal, Québec, Sherbrooke, Trois-Rivières and Gatineau should integrate a few communities within their respective CMA.
* Montréal (including St-Jean) would be around 6,22 M.
* Québec would have grown enough to absorb Donnacona, St-Ferréol, St-Apollinaire and Pont-Rouge. The metropolitan area would be around 1,15 M people.
* Gatineau (the Québec part of Ottawa) : ~442 k
* Sherbrooke/Magog : ~341 k (including Windsor and East Angus)
* Trois-Rivières, slow but steady growth, the long awaited high speed train is not built yet in 2050
: ~199,5 k
* Saguenay, quite stable : ~177 k
* The surprise will probably be Granby/Bromont. The increasing commuting of Waterloo/Shefford towards the centre of the agglomeration will push it to ~152 k
* Drummondville will probably continue to grow to ~138 k
* Finally, located at the doors of Montréal, Joliette will continue its steady growth to become a real satellite city at ~113 k.

- Sherbrooke 237 k.
- Trois-Rivières 162 k.

Regions:
Gaspésie and Côte-Nord will continue their decrease. Côte-Nord could hypothetically lose its administrative region status, with a population of less than 69000.
Estrie will see its relative importance increase, with RCMs of Haute-Yamaska and Brome-Missisquoi leaving Montérégie to join a new "Cantons-de-l'Est" administrative region (this process is already in motion in 2020). New Cantons-de-l'Est: 624 k. New Montérégie: 1,8 M.
Villages:
If the depopulation phenomenon continues, a few villages/municipalities could face closure, of become seasonal-only / cottage-only territories.
