Here's my comments/suggestions for new riding names (what else would you expect from me!):
Les Plaines: Not a bad name, considering it contains Sainte-Anne-des-Plaines and the La Plaine sector of Terrebonne. The name doesn't cover the Saint-Janvier sector of Mirabel though, so how about Les Plaines--Saint-Janvier
? If you don't mind long names, then the more inclusive name would be Sainte-Anne--La Plaine--Saint-Janvier.
Prevost: Obvious desire to re-incarnate the old riding name since it includes the municipality of Prevost. However, Prevost contains only part of the riding (I realize it was also named for the family). Prevost is the largest city in the riding and the second largest municipality. I can't really think of a better name for the district at the moment. Any ideas?
Mont-Royal--Outremont: Not a bad name, but the riding contains part of Cote-des-Neiges, so at the risk of having a long name, howabout Mont-Royal--Outremont--Cote-des-Neiges
Masson -> Mascouche (obviously)
Terrebonne -> Terrebonne (only loses a newly annexed suburb of the city anyways)
Mirabel -> Mirabel. Not the best name, as the riding contains some territory on Lac Deux-Montagnes, but losing Saint-Janvier still puts most of the riding in Mirabel. Plus, Deux-Montagnes is in another riding of the same name.
I think this riding was a point of contention last time I created alternative riding names. I wanted Les Laurentides I think, but it was too general?
Rousseau -> Montcalm. Territory is now the entirety of this MRC, so it's an obvious name.
D'Arcy-McGee -> Cote-Saint-Luc--Hampstead or Cote-Saint-Luc--Hampstead--Snowdon.
Notre-Dame-de-Grace -> Notre-Dame-de-Grace--Montreal-Ouest. The riding now contains all of these two places.
Mercier -> Mile-End or Mile-End--Laurier. This riding contains all of Mile-End now.
Westmount--Saint-Louis -> Westmount--McGill. The riding contains Westmount plust the area around McGill University.
Saint-Henri--Sainte-Anne -> Le Sud-Ouest? I hate that name, but it is the Borough name that the riding now has the exact same boundaries with. Also, the alternative is way too long: Saint-Henri--Saint-Paul--Pointe-Saint-Charles--Emard (based on a similar 1990s federal riding name, which was just as long).
Maskinonge -> Maskinonge--Saint-Maurice: Maskinonge already contained much of the historic Saint-Maurice County. Now that Saint-Maurice is dead, might as well add the name to this riding, especially since it gains even more of Saint-Maurice.
Champlain -> Champlain: The new territory is also located in the historic Champlain County. A more modern name for the riding could be Les Cheneaux--Cap-de-la-Madeleine reflecting the MRC and the community in Trois-Rivieres which is also in the riding.
Trois-Rivieres -> Trois-Rivieres: Just loses a neighbourhood.
Laviolette -> Shawinigan--Mekinac--La Tuque. The old part of Shawinigan has been transferred to this riding, so it makes sense to include it in the name. The riding also includes Mekinac and La Tuqe MRCs.
