Shipping and trade was specifically exempted from this restriction. I'm not certain if that might really complicate truck-carried goods but in theory goods moving is unrestricted.

My suspicion is that doing these restrictions for air and sea ports may be easier than for our land border. Also it seems like everything is on the table. Maybe more time is needed to ensure these exchange of goods and services aren't impacted by closing the land border.

As I was listening to the followup discussion by the ministers that was my charitable read - that closing the border would cause supply chain issues because truck drivers would be uncertain if they could cross the border or companies might not even attempt to send goods up... So I do agree that's a possibility, but it seems like if that was the emphasis it could have been expressed much more clearly.

I think you hit the mark. The government will need to allow American truckers, air freight and rail crews to cross no matter what.

Also, residents of Point Roberts, WA who must drive through Canada to access the rest of Washington state.

Why not change rail/truck crews/drivers at the border or stations closest to the border?

Imagine the complexity of that. Mind boggling.

Yeah, the risk-to-reward ratio for that would be ... high.

Yeah in general, logistics needs to remain unimpeded or you hit a whole new level of problem.

this whole covid19 business would be a lot easier to deal with if blockbattle.net were up and running :-) (not sure of a better way to notify on outages, would love to discuss)
