Pointe-Claire Village is less a prewar suburb than a rural village that predates (sub)urbanization. Same with Ste-Anne-de-Bellevue, Saint-Geneviève and Pointe-aux-Trembles. In Laval, you have St-François and Ste-Rose in similar situations. On the South Shore, there's La Prairie and Boucherville, and on the North Shore, St-Eustache and Charlemagne, among others.
Here's
one view and
another of Charlemagne – it's a good example of an old "noyau villageois" that hasn't been upgraded or gentrified, unlike St-Eustache, Boucherville, La Prairie, etc.
That said, Pointe-Claire was indeed a small railroad suburb served by the Hudson line that started service in 1887. But the prewar commuter suburb was concentrated around Valois station which is nearly 4km away from Pointe-Claire Village. You can see it on Google Maps
here – the typology is completely different and has more in common with other railroad suburbs from the early 20th century. For instance,
Highland Park in LaSalle, which is another prewar railroad suburb.
Also worth noting: Vieux-Longueuil, Ste-Thérèse and Terrebonne all have a bit of the village typology going, but they were more than just rural villages, they were towns important in their own right that just happened to be absorbed by Montreal's urban sprawl. Kind of like Brampton vs. Unionville in a GTA context.
