Want an idea of what one of the start-up costs was? Have a look at this Federal Court decision:
http://www.canlii.org/en/ca/fct/doc/201 ... fc1335.pdf
[19] In the result, Toronto Port Authority is awarded $705,131.35 for costs and taxes and
$194,851.15 for disbursements which, in total, is $899,982.45. Porter is awarded $836,248.65 for
costs and taxes and $156,422.88 for disbursements which, in total, is $992,671.53. These awards
include applicable taxes.
$1.9 million in costs and disbursements alone, that Air Canada had to pay as a result of losing its case. That doesn't include the bill from its law firm, McCarthy Tetrault LLP. (probably about the same amount). And these costs were only a small part of the whole package related to the Toronto Island Airport proposed operations.
