yes. The Province listed the Crosstown LRT as $4.9 billion in 2010 dollars, but the actual contract signed was closer to $7 billion IIRC.
Its the same reason its not fair to compare the $3.2 billion cost to the $1.5 billion cost for the LRT option, as the LRT price tag is not escalated. The TTC published an estimated escalated cost of the LRT, and it was something like $2.5 billion. Supporters of the LRT called it bullcrap of course, refusing to believe those numbers. Apparently the LRT is immune from cost changes but the subway is possible to see infinite increases into the trillions.
Its why the original pricetag on the subway was so low, as it was in 2010 unescalated dollars for councillors to compare between the two projects. They switched to escalated dollars after the vote as that is how it is normally financed. TorStar with its vendetta against the project just ran with it making it seem like a huge cost escalation, while the truth was that it was really just an accounting change.
There has been a small "real" increase in costs, from $2.9 billion escalated to $3.2 billion escalated. There was an initial jump from $2 billion to $2.9 billion, which was the accounting change, then it went to $3.2 billion, which was a "real" cost overrun.
Besides, costing changes are expected at that stage as the cost estimates were extremely preliminary in those original decisions.
