It  is Canada's responsibility to get a handle on our fentanyl labs, organized crime in the trucking industry, money laundering -- and a toothless justice system that sends serial  traffickers back on the street like a revolving door.

If US customs has to physically  inspect every commercial truck bound from Canada for drugs because curbing the flow of our failures is "their responsibility", expect the consequences for those failures to get worse. 

The criminal behaviour damages us more than it does the US, so one would think it's in our best interests to do something about it, yes?
