Kingston (Bath), Brampton (Alstom). I believe there's a facility in Sorel. And almost in Canada, is the facility in Plattsburgh; I've known Canadians commuting there daily from just across the border.
Off the top of my head.
Don't forget Hornell and Elmira NY, which are relevant competition to Bombardier and just across the border.
Railcar assembly is a nomad's existence. There are components that demand heavy foundries or specialised shops that have ongoing existence, sure.... but transit assembly plants work on the basis of one production run, maybe a repeat order if lucky.... the investment in the production infrastructure is nowhere near what is contemplated to build autos (or TV sets, for that matter). I doubt anybody in say Alstom Brampton expects the same degree of job security as people at Toyota in Cambridge (and even then, those workers are at the mercy of where Toyota is considering building as its next model, which may demand a new production line somewhere).
What St Thomas has going for it is connectivity to the "network" of auto plants and parts manufacturers between Chicago, New York, and Cincinatti. You won't see an auto plant spring up in Winnipeg as the supply chain ain't there. The "micro" analysis of how we landed in St Thomas (or Windsor) lies within that macro reality.
So, sure, if VIa were to reequip its long distance fleet, there will be builders in Ontario and Quebec trying to land the work....but an asssembly line in Ontario that continues to churn out passenger railcars for a decade or more is a fantasy. Amfleet, Superliner, Viewliner fleets all had a beginning and an end. Where are their factories today. Venture and Acela will too.
Toronto only needs so many subway cars. Thunder Bay has done well, and I hope that continues, but even there periodic layoffs and recalls are a reality.
