(Ce

As defined by section
12 of the Motor Vehicle Safety Act, a Technical Standards Document
(TSD) is a document that reproduces an enactment of a foreign government
(e.g. a Federal Motor Vehicle Safety Standard issued by the U.S. National
Highway Traffic Safety Administration). According to the Act, the Motor
Vehicle Safety Regulations may alter or override some provisions
contained in a TSD or specify additional requirements; consequently, it
is advisable to read a TSD in conjunction with the Act and its counterpart
Regulation. As a guide, where the corresponding Regulation contains additional
requirements, footnotes indicate the amending subsection number.
TSDs are revised from time to time in order to incorporate amendments
made to the reference document, at which time a Notice of Revision is
published in the Canada Gazette, Part I. All TSDs are assigned
a revision number, with "Revision 0" designating the original version.
Identification of Changes
In order to facilitate the incorporation of a TSD, certain non-technical
changes may be made to the foreign enactment. These may include the deletion
of words, phrases, figures, or sections that do not apply under the Act
or Regulations, the conversion of imperial to metric units, the deletion
of superseded dates, and minor changes of an editorial nature. Additions
are underlined, and provisions that do not apply are stroked
through. Where an entire section has been deleted, it is replaced
by: "[CONTENT DELETED]". Changes are also made where there is
a reporting requirement or reference in the foreign enactment that does
not apply in Canada. For example, the name and address of the U.S. Department
of Transportation are replaced by those of the Department of Transport.
Effective Date and Mandatory Compliance Date
Compliance with the requirements of a TSD that is being introduced
for the first time is not mandatory until six months after publication
in the Canada Gazette, Part II, of the Regulations that incorporate
the TSD. In the case of a revision, compliance becomes mandatory six months
after publication of the Notice of revision in the Canada Gazette,
Part I, as long as the requirements of the previous version continue to
be met. Voluntary compliance is permitted as of the Effective Date of
the TSD.
