PG said "I'm currently in BC, have been travelling back and forth to the States since April of 2020 with exactly zero incident. ...mind you, these have all been trips involving commerce. "
We are in Langley, with four crossing ports we can choose from. However it is hit and miss as to the border agent you get - my hubby has had business related equipment sitting in a border services place in Blaine Washington for over a year. He has tried twice to get across to get the stuff - both times he was refused entry, even though if you call a supervisor they say they would allow you - but it is at the discretion of the agent you get at the time.
My boss has crossed that border numerous times over the past year via private helicopter with almost no issues. However the one time he came home he was refused re-entry into Canada at one port (abbotsford) - so he flew over to YVR and was admitted.
Sadly border patrol agents on both sides of the border have been given too many "ambiguous" rules that they can apply or ignore on their own.
Hopefully soon we can get back to life again.
