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). 2012/__/___ Page 7 of 7
