@Minniemoo15 Same question as I was asking over on the air travel policy thread.
He would need to test in Montreal then continue to Halifax (I am from Halifax!). I have no idea if they are using rapid testing or what. Halifax airport is using the rapid tests, I believe.
BUT, a big but, what if his test in Montreal came back positive? He would need to isolate in Montreal until he got negative test. He would likely need to present a quarantine plan in Montreal FOR Montreal in case this happened. This is how I am understanding all of this.
