Ontario Dangerous Goods Transport Guide for Tradespeople
Ontario tradespeople—including electricians, HVAC technicians, and plumbers—often transport flammable liquids, compressed gases, or corrosive substances. Non-compliance with Canada’s Transportation of Dangerous Goods (TDG) Regulations, enforced under the federal Canada Labour Code and aligned with Ontario’s Fire Code and Occupational Health and Safety Act, can lead to fines up to $50,000 or imprisonment. This guide clarifies your legal duties, certification requirements, and provincial enforcement responsibilities.
1. Legal Framework & Key Regulations
Transporting dangerous goods in Ontario is governed primarily by the federal Transportation of Dangerous Goods Act, 1992 and its associated TDG Regulations (SOR/2001-286), administered by Transport Canada. Ontario-specific obligations stem from the Ontario Fire Code (O. Reg. 213/07), Part 6 (Hazardous Materials), and the Occupational Health and Safety Act (R.S.O. 1990, c. O.1). The Canada Labour Code (Part II) applies to federally regulated workplaces but does not override provincial enforcement for most trades. Crucially, Ontario does not issue standalone 'dangerous goods licenses'—but trade licensing via the Ontario College of Trades (now Skilled Trades Ontario) requires TDG training verification for relevant scopes. CRA does not regulate transport directly, but improper handling may trigger tax-related audits if safety incidents impact business operations.
2. TDG Certification & Training Requirements
All Ontario tradespeople who handle, offer for transport, or transport dangerous goods must hold valid TDG training certification, renewed every 3 years per TDG Regulation §6.2. Training must be employer-provided and documented, covering classification, packaging, labelling, placarding, shipping documents, and emergency response. Unlike some provinces, Ontario does not mandate third-party accreditation for trainers—but content must align with Transport Canada’s TDG Training Standard. Skilled Trades Ontario recognizes TDG certification as essential for journeypersons in gasfitters, refrigeration mechanics, and welders. Proof of training must be retained for 2 years post-employment. Failure to maintain current certification risks penalties under both TDG Regulations and Ontario’s OHSA, which holds employers liable for worker safety during transport-related activities.
3. Vehicle, Packaging & Documentation Rules
Ontario trades must use UN-certified packaging appropriate for each substance class (e.g., propane cylinders meeting CSA B339). Vehicles require proper placards (e.g., Class 2.1 flammable gas diamond) when carrying ≥150 kg aggregate quantity, per TDG §4.10–4.15. Shipping documents must accompany all shipments and include consignor/consignee details, UN number, proper shipping name, class/division, and emergency contact. Ontario’s Highway Traffic Act (R.S.O. 1990, c. H.8) empowers police to inspect vehicles for compliance; non-compliant loads may be refused entry at construction sites or municipal depots. Note: Ontario Fire Code §6.10.2.2 requires secure storage of DGs on-site—even during short stops—preventing unauthorized access or ignition sources. Always verify container integrity and valve functionality before transport.
4. Enforcement, Penalties & Provincial Oversight
In Ontario, TDG enforcement is shared: Transport Canada inspectors conduct roadside and workplace audits, while the Ministry of Labour, Immigration, Housing and Skills Development (MLIHS) enforces OHSA provisions related to transport hazards. Fines range from $5,000 (first offence) to $50,000+ (subsequent) under TDG Regulations; criminal charges apply for willful violations. Ontario courts have upheld convictions under R. v. SNC-Lavalin (2018) for TDG non-compliance linked to site incidents. Skilled Trades Ontario may suspend certifications for repeated safety breaches. Municipal bylaws (e.g., Toronto Municipal Code Chapter 747) also restrict DG transport in certain zones. Keep records of training, manifests, and vehicle inspections for 2 years—required under TDG §6.10 and Ontario’s Archives and Recordkeeping Act.

Do I need a special driver’s licence to transport dangerous goods in Ontario?
No—Ontario does not require a special driver’s licence for DG transport. However, you must hold valid TDG training certification, appropriate vehicle insurance, and comply with all TDG packaging, labelling, and documentation rules. Commercial vehicle operators may need a Class D or higher licence depending on vehicle weight, per Ontario’s Highway Traffic Act.
Is TDG training required for small quantities like one 20-lb propane cylinder?
Yes—if you are offering it for transport (e.g., delivering to a job site), TDG training is mandatory regardless of quantity. Exceptions exist only for ‘limited quantities’ under TDG §1.17 (e.g., <30 kg net mass of certain Class 3 flammables in approved containers), but most trade-related DGs—including propane, acetylene, and refrigerants—do not qualify. Always verify using Transport Canada’s TDG List of Dangerous Goods.
