Toronto's choice of using LRT, the most expensive option available between subway, SkyTrain, and monorail, had nothing to do with Toronto and everything to do with Thunder Bay.
Even Ford would love to be able to say Eglinton is getting a real subway as opposed to a tunneled LRT but Queen's Park would have none of it. Those LRT trains are being built in Thunder Bay and that meant real jobs for that depressed area. This was an election year and everyone knew that McGuinty wwould not get the cakewalk he did in the last 2 elections and he needed every seat available.
Now that the election is over Queen's Park may be willing to change their technology choice. As long as Bombardier gets the same size contract I can't imagine them bitching too much as no manufacturing of the LRT trains will begin for years.
