I can answer from a commercial perspective.
Commercial traffic has declined over the last 20 years. Part of that has been because of the shift of trade between Canada and the U.S. in the automotive industry to Mexico and the United States, as well as receiving more goods through seaports such as Prince Rupert, Vancouver, and Halifax.
We're seeing more of what we call “outside the trade”. The stuff that's going back and forth between Canada and the U.S. has declined over the last number of years.
