Chill out. Closing the border means not allowing passenger transport, not turning back freight/cargo. Even Europe keeps the trucks going through their closed borders.

Not just trucks but people working and etc

Just to clarify - all of these travel restrictions apply to non-logistical/essential persons only and Canada still is emphasizing that goods movement won't be restricted - it's important too since Canada is a net importer of food.

They wouldn't ban trucks carrying cargo, supplies, etc.

Which, due to the closeness of the US/Canada relationship, makes it pretty pointless. Unless they do something involving disinfecting truck cabins then switching from US to Canadian drivers, at the border.

Every trucker who goes to Canada pops into a Tim Hortons before heading back to the US, no exceptions.

Don't let perfect be the enemy of better-than-nothing. Especially when we're talking about individual truckers vs. tens of thousands of close packed poor-environment-suffering groups of people in transit hubs.

Disallowing close-packed passenger travel while still allowing essential logistics _curbs_ even if it does not halt. Just because it's not the solution doesn't mean it's not worth doing.

I agree with you in general.

I'm saying that, epidemiologically speaking, Canada and the US should be treated as one entity. This is probably the case for border regions of Mexico as well, though I see no reason to allow flights to or from D.F. at the moment.

If (it's probably when) we start to see domestic travel restrictions, curbing transport between states, that's a good time to restrict the border as well.

I believe a lot of those in particular aren't US originating, but if they are, probably not to a critical extent. Many of them Chinese, or maybe passing through the U.S, but not all that much more critical than leisure travel anyway.
