Granted, the plan does include funding for "Express GO Transit rail service from downtown Toronto to Hamilton, Oshawa, Brampton, Richmond Hill and Mississauga, running every 15 minutes, all day, in both directions". If Ottawa's plan were amended to include rail from Kanata, Barrhaven, Orleans, and possibly other suburbs the price tag would certainly rise, but $55B?
Best comment on the story comes from RD Lone of Vancouver:
"They should just make a series of long conveyer belts along Eglinton like in the Jetsons. I bet it would cost less than $50 billion."
