I don't really know the whole history of U.S. preclearance at Canadian airports, but was it really due to American bullying? It truly seems like a mutually beneficial arrangement - one where passengers and airlines from both countries reap a real benefit.

I'm thankful the U.S. government is willing to provide the service and that than Canadian government allows them to do so.

Take it away, and we all lose a lot of travel options. Our transborder traffic becomes more hub-to-hub, adding connections for everyone.
