Bit of a noob question, piggyback
I've got a noob question but because of COVID, I simply don't know the answer, and it relates to your Halifax-Montreal-USA route.
I'm travelling YUL-YYZ-LAS, but can't see clearly where I pre-clear US customs? In YUL or in YYZ? Did you pre-clear in Halifax? Do they have pre-clear in Halifax?
Thanks all.
