I'm not. But too many people wish the GTA was like Berlin: two separate and parallel transit systems which require passing through a military checkpoint to transfer between them. West Berliners boycott the S-Bahn, because it was owned by the GDR Government and they didn't want to fund them.
In all seriousness, I doubt there will be any serious opposition to extending at least the Yonge Line if it weren't for the municipal boundary. The Spadina Line extension can go to hell north of Steeles, but that's a different matter.
It has nothing to do with the fact that projected utilization of said projects within the 25 year timeframe predict that during the busiest hours--AM peak--that the $5 billion worth of capacity will be up to 80% unused.
Uh...wut? Perhaps for the Spadina Line into Vaughan, but definitely not for the Yonge Line. I don't believe the standing-room conditions on the Yonge Line at Finch will suddenly vanish if the tunnel is extended north.
It makes about as much sense as building a subway line out to the Beaches or to Malvern and yes I'd call those foolish expenditures too.
Last I checked, there are so many idiots arguing the subway should never touch the 905 because "our" 416 tax dollars should not be paying for something on "their" side. They won't be satisfied until there are concrete walls, landmines, razor wire, and soldiers with shoot-to-kill orders on Steeles Avenue.
