If you transport cargo from the US into Canada, you need to learn about the eManifest program.
This program, implemented by The Canada Border Services Agency, requires electronic data about your cargo and the vehicles to CBSA before crossing the border. As of November 1, 2012 you will be required to use the eManifest program. Failure to do so will result in you being denied entry. Penalties may also be levied although penalties will be zero-rated (i.e. non-monetary) until May 1, 2013.
It seems that not everyone realizes that unmarked tiedowns are no longer allowed for Cargo Securement in Canada.
As of January 1, 2010, tiedowns and components that are not marked with their working load limit (or grade in the case of chain) can no longer be used. Check all of your tiedowns to ensure that they are properly marked.
Section 11(4) of the National Safety Code Standard 10 has been rewritten as of the September 2010 edition of the code to read as follows:
(4) A person shall not use a tiedown or a component of a tiedown to secure cargo to a vehicle unless it is marked by the manufacturer with respect to its working load limit.
Most of Section 12 dealing with how to treat unmarked tiedowns has been deleted. Only subsection 9 remains, dealing with unmarked friction mats.
