Trudeau airport set to undergo $2.5 billion expansion

Montreal's Trudeau airport is set to undergo a major expansion and renovation, which is expected to last through 2030 and cost $2.5 billion.

Among the improvements will be a new terminal, as part of an effort to meet growth projections for the airport, and a brand new multi-level parking lot and drop-off zone for cars.

Last year, nearly 20 million passengers came through Trudeau airport, but the airport authority, Aéroports de Montréal, says the airport has been growing beyond the international average over the past few years.

"Our growth North America should be anywhere from 3 to 4 per cent. And we're above 7...up to 9 and a half," says Aéroports de Montréal boss Philippe Rainville. "Huge numbers. We have to react. We have to do something."

Rainville says the work will begin at the same time work begins on the new REM light-rail station at the airport. That's expected to be up and running by 2023.

The money is expected to come mainly from long-term loans, though Rainville says he doesn't expect to implement an airport improvement surcharge on people's airline tickets — at least not for the moment.
