Transport Canada has posted an alert on their website that deals with US carriers transporting dangerous goods into Canada.
Section 6.4(1) of the TDG Regulations states that a carrier from the US must have a hazmat endorsement on their commercial driver’s licence and that this endorsement must reference sections 172.700 to 172.704 of 49 CFR (Code of Federal Regulations). As the hazmat endorsement is state generated, not federal (DOT), not all endorsements make reference to those sections of 49CFR.
However, Transport Canada has an agreement with the Federal Motor Carriers Safety Administration (FMCSA) that Transport Canada will recognize the hazmat endorsement on the CDL.
