TransCanada then confirmed this past July that the project would cost at least $3.4 billion, adding it "may exceed that amount by approximately 10 per cent" – or another $340 million.
This would bring the total overrun to nearly $1 billion, or 36 per cent above the original cost estimate.
Hey, this is not bad for an overrun! But I think they are being coy with the true cost, since the delay has monetary value. Much like they hide the best-estimate true cost of the Niagara Tunnel!
If something actually works, I think twice as expensive and twice as much, is pretty good! Trouble is, nothing is working anymore!
