I can't imagine Canada is very happy about the US travel ban. It may increase traffic through Canadian airports as people attempt to get to their destination. So, yeah.
Deputy Prime Minister Chystia Freeland said she's like to have a serious conversation with the US about how friends/neighbours behave. Freeland immediately contacted the US Ambassador and many others - so conversations are ongoing now. Let me just say, Chrystia Freeland's face tells a story. Like it or not, she is pissed.
@Anemone This is a fear for the UK too....
