The cross border vaccine mandate for truckers in/out of Canada is now in effect.  The U.S. vaccine mandate takes effect on January 22nd.

Keep in mind, any impact is taking place in a supply chain system that is already tenuous and unstable at best.  A small disruption that may have been minimally significant against a fully operational supply chain, is more likely to be a much bigger disruption in a supply chain that is already under a severe amount of demand side stress.  Somewhere in the range of 16,000 to 38,000 daily loads are likely to be impacted.

you should listen cause it effects America too
