Provincial adoption and edition rule. Model codes and standards only become law where your province or territory adopts them, often with amendments, and the edition in force is the one your province, inspector, contract or engineer names. These summaries are study notes in our own words, not the code text. Always check the current adopted edition, your site procedures and your supervisor or inspector.
Automotive Service Technician
- CMVSS (Canada Motor Vehicle Safety Standards)
Federal safety standards for brakes, lighting, airbags, seat belts and more. They apply to every road vehicle. Repairs and modifications must keep the vehicle compliant, and provincial safety inspection standards build on this. - OBD-II on-board diagnostics
The standard diagnostic connector, generic powertrain codes (P0xxx) and readiness monitors on light vehicles. It applies when you diagnose a check-engine light or confirm a repair, and readiness monitors must set before some emissions or inspection checks. - Emissions rules (federal and provincial)
The On-Road Vehicle and Engine Emission Regulations under the Canadian Environmental Protection Act set emission standards, and tampering with or removing emission controls is prohibited. Provincial programs and inspections vary by province. - Refrigerant handling (provincial rules)
Recovery of A/C refrigerant and technician certification for ozone-depleting and halocarbon refrigerants are set provincially. They apply on any A/C service. - Provincial safety inspection standards
Each province publishes its own standard for safety certificates, such as brake lining minimums, tire tread and lighting. It applies when you sign off an inspection.

Provinces adopt the NBC, some with their own versions (Ontario, Quebec, BC and Alberta each publish one). - NBC Part 4 (engineered structures)
Larger or complex buildings fall under Part 4 and are designed by an engineer. You build to the stamped drawings rather than the Part 9 span tables. - CSA O86: Engineering design in wood

Safety standards that equipment is tested and certified to. Rule 2-024 says installed electrical equipment must be approved, which in practice means a recognized certification mark (such as CSA, cUL or cETL). If equipment has no mark, it needs a special inspection before you energize it. - Hazardous locations (CEC Section 18, with Section 20 for fuel dispensing and similar locations)
Areas where flammable gas, vapour, dust or fibres can be present. Areas are classified (the Zone system for gas, and Classes and Divisions on older work), and the wiring methods, seals and equipment ratings change to suit. It applies at fuel stations, paint booths, gas plants and anywhere the engineer's area classification drawing shows. - CSA Z462: workplace electrical safety
