Ontario Inspection Guidelines

Differences Between Inspections

The National Safety Code 11B Periodic Commercial Motor Vehicle Inspections (National Standard) provides greater detail and specific inspection and pass/fail criteria, and reflects recent technological enhancements found in today’s vehicles.

The National Standard manual is made up of three separate parts:

  1. Truck and Truck Tractor
  2. Trailer, Semi Trailer and C-Dolly
  3. Bus

Each page is divided into two sections, the left side of the page clearly lists the item and method of inspection and the right side of the page lists the corresponding rejection (pass/fail) criteria and highlights criteria that is considered hazardous. Each part is organized further into sections of the vehicle:

  1. Power Train
  2. Suspension
  3. Hydraulic Brakes
    3A. Air Brakes
  4. Steering
  5. Instruments and Auxiliary Equipment
  6. Lamps
  7. Electrical System
  8. Body
  9. Tires and Wheels
  10. Couplers and Hitches

The next few pages highlight the key differences between the National Standard and the previous Ontario inspection under Regulation 611 schedules 1, 2 and 4 for each type of vehicle (truck, trailer and bus) within each of the 10 sections. The intent of this document is to provide a guideline to assist inspection technicians, owner/operators and enforcement identify changes in the requirements with the adoption of the national standard. This overview does not represent the inspection itself or decisions made regarding interpretation of the standard.

Activities listed below are not the complete inspection and does not include the rejection criteria for the vehicle. Detailed inspection and rejection criteria are contained in the National Standard.

Please Note: To see the details of this inspection see Regulation 611 "Safety Inspection” at the following link: http://www.e-laws.gov.on.ca/html/regs/english/elaws_regs_900611_e.htm and copies of the inspection can be obtained for a cost at the Canadian Council of Motor Transport Administrators (CCMTA) at the following link: http://www.ccmta.ca/english/producstandservices/publications/publications.cfm.


Identified Differences between The National Standard and Previous Ontario Inspection Requirements

Section Identified Differences
(T) = Truck, (Tr) =Trailer, (B) = Bus
Power Train New:
  • Inspection of the adjustment/disengagement of the clutch and condition of the engine mount. (T&B)
  • Inspection of the starter by starting a bus three times in succession. (B)
  • Inspection of all accessory drive belts, where current Ontario inspection requirements did not require inspection of drive belts. (B)
  • Previous Ontario inspection requirements require measurement of the length of exhaust systems or drive shaft guards (T&B)
Suspension New:
  • Inspection of the kneeling feature ensuring it engages when the switch is activated and it is not leaking. (B)
  • The National Standard requires a more a detailed inspection of the suspension, outlining rejection criteria based on the type of suspension. (all)
  • Method of testing the air pressure protection valve to stop air flow remains the same only the rejection criteria has changed. (all)
Hydraulic Brake System/ Air Brake System New:
  • Brake drum diameter and lining thickness to be recorded. (all)
  • Anti-lock brakes operating on vehicles manufactured after July 1, 2011 and as of 2014 on all vehicles originally equipped (all)
  • Inspection of the break-away system to ensure it is equipped and operating. (Tr)
  • Spring brake control valve to be operating and securely mounted. (Tr)
  • Visual and audible inspection of the tractor protection system, if applicable. (tractor protection valve & trailer supply valve) (T&B)
  • The National Standard requires a low air pressure warning system with a visual indicator and previous Ontario inspection allowed for a visual or audible indicator. (T&B)
  • The National Standard does not require a performance brake test. (all)
Steering New:
  • Telescopic/tilt steering to lock in position and not have excessive play. (T&B)
  • Inspection to ensure operation of pressure regulator and pressure gauge on trailers. (Tr)
  • Both standards have the same test for steering lash, however the rejection criteria is different. Overall, the National Standard allows a greater amount of steering lash than current Ontario on road requirements but is still well within safety parameters. (T&B)
Instruments and Auxiliary Equipment New:
  • Visual inspection of the following, with rejection criteria including missing, excessively warn or broken:
    • clutch and pedal (T&B);
    • chain/headache rack (T);
    • indicator light for anti-lock brakes and airbags (T&B); and,
    • indicator light for flashing light on school bus (B).
  • Visual and manual inspection of permanently attached equipment to a trailer to ensure it is secure. (Tr)
  • Inspection required to ensure securement mounts are not missing or damaged for heater/refrigeration units only. (Tr)

Electrical System New:
  • Rejection criteria for a visual inspection of battery, switches and trailer cord, such as missing or broken. (T&B)
  • Visual inspection of the condition of the wiring. Previous Ontario inspection requirements only refer to the location of wires. (all)
  • Alternator must be inspected on school buses. (B)
Body New:
  • Different standards and greater detail for many body types, where previous Ontario inspection requirements applies one standard for all body types. (all)
