Currently the Canadian/US border is open on a limited capacity. Traffic is at a single file and every vehicle is being completely searched. You obviously can imagine the americans paranoia.
Airline passenger are mostly being bused to LA/Seattle if they are heading into the states. Many however are stuck without accomodation in Vancouver. I have not heard how these passangers are being cared for. The canadians are typically going above and beyond the call of duty.
TV is quoting that the American response will not be cruise missles but more than that. This could be all out warfare.
VERY bad day for all of us.
