Breathtaking! I share your apparent fondness for resurrecting old riding boundaries (and names--I'm delighted to see St. Andrew-St. Patrick making a comeback). I'm truly sorry that such a large legislature would never fly politically--I have always believed Dalton Camp had the right idea back in the 70s.
In my view, the population inequality in Ontario's current riding map is constitutionally intolerable. My number one beef with the Wynne government was that they didn't try to adopt the (admittedly imperfect) new federal boundaries so voters in the June election could have at least roughly equal votes. But this solution, if by some miracle it were to be adopted, would be the best possible outcome. Congrats for undertaking all this work; a slightly more detailed map, though perhaps technically infeasible for you, would be even better!
It wouldn't have been legal and possibly not constitutionnal. A delay must be allowed to parties to do the needed changes to their internal organisation (riding associations, changing the riding of every member...). Usually, laws provide a 6 to 9 months period to do that.
