2012: What’s New?


Security of Loads - Regulation 363/04

Regulation 363/04 was recently amended to adopt the most recent version of National Safety Code (NSC) Standard 10 (Cargo Securement)dated September 2010. Future updates to NSC Standard 10 will be adopted automatically by reference in Regulation 363/04. This will ensure that Ontario’s regulations are harmonized with other Canadian jurisdictions in a timely manner. These changes took effect on July 1, 2012.


Critical Defects of Commercial Motor Vehicles – Regulation 512/97

Regulation 512/97 was amended to include an inoperative brake as one of the critical defects for the purposes of the Commercial Vehicle Impoundment Program (CVIP). A commercial motor vehicle or trailer equipped with an air brake system, other than an air-over-hydraulic brake system, has an inoperative brake for the purposes of commercial vehicle impoundment if, when the brake actuator is applied:

  • There is no movement of the chamber push rod, slack adjuster or cam shaft,
  • Neither of the two shoes moves, or
  • Neither of the two shoe linings contacts the drum.
The regulation was also amended to clarify that the measurement of travel of a push rod out of a service brake chamber must be taken with the initial air system pressure between 90 and 100 psi. These changes took effect on July 1, 2012.
