Explanatory Note
These cylinders have previously been manufactured under a permit granted
pursuant to the Regulations for the Transportation of Dangerous Commodities
by Rail. The applicant had demonstrated that by restricting certain design
parameters as well as the types of gases that could be contained, a cylinder of
reduced wall thickness could be manufactured with equivalent safety. This
certificate authorizes continued manufacture and use of the cylinders under the
Transportation of Dangerous Goods Regulations.

NOTE
Under Canadian Law, a foreign manufacturer of non-specification cylinders
cannot be charged with an offence under the Transportation of Dangerous
Goods Act, 1992 for failure to comply with the conditions of a Certificate.
However, certain remedies under the Act are available to Transport Canada in
this eventuality.
These include:
1. detention of dangerous goods and consequently the means of containment
containing them (subsection 17(1));
2. detention of the means of containment whether full or empty
(subsection 17(1));
3. directions not to import the means of containment or to return them to origin
(subsection 17(3));
4. inspectors’ directions (section 19);
5. directions to importers of the means of containment to issue notices of
defective construction or recall (subsection 9(2)); and
6. revocation of the Certificate, thereby making any use of the means of
containment an offence (subsection 31(6)).
If none of the foregoing are adequate, Protective Directions may be issued to
prohibit or to control the use of the means of containment (section 32).
