This argument seems basically identical to the people who argue that road diets raise GHG emissions due to having more cars idling at lights. A modicum of planning knowledge tells us this isn't true, because infrastructure induces demand -- a new, more remote airport opens up with cheaper fees so all the budget airlines relocate there, it becomes much harder to get to via transit so people are more likely to drive there, lower fees mean (at least theoretically) lower cost of air travel, so people are more likely to fly frivolously rather than approach it as the weighty decision it should be. Even more insidiously, short domestic/regional flights (which still emit tons of GHG due to takeoff and landing) become normalized and cheap and further undercut the market for passenger rail, in exactly the usage case where passenger rail belongs -- not the long intercontinental flights that trains physically can't make unless someone teaches them how to swim.
I would agree that we have this airport built, only if all major cities in Canada are served with daily passenger rail.
