The U.S. had a more liberal container policy than Canada. A foreign
container can be used anywhere in the U.S. for a period of one year providing it is carried on a U.S.-owned vehicle. Containers in the U.S. are
regulated as if they are“reusable packaging”. In Canada, container cabotage regulations more closely resembled the restrictions on foreign trucking. Only one incidental repositioning move was permitted, with
no backtracking. Containers were given only 30 days in Canada before
being re-exported.
