Dangerous Goods Transport Regulations for Tradespeople in Ontario
Ontario tradespeople—including HVAC technicians, electricians, painters, and plumbers—routinely transport flammable liquids, compressed gases, and corrosive substances. Failure to comply with the federal Transportation of Dangerous Goods (TDG) Act and Ontario-specific enforcement rules can trigger fines up to $50,000, licence suspension, or criminal charges under the Canada Labour Code. This guide clarifies your legal obligations using binding authorities: the TDG Regulations (SOR/2001-286), Ontario Regulation 102/07 (under the Occupational Health and Safety Act), and requirements tied to provincial trade licensing via the Ontario College of Trades (now Skilled Trades Ontario).
1. Legal Framework & Applicability in Ontario
The federal TDG Act and Regulations apply to all dangerous goods transport in Canada—including intra-provincial movements in Ontario. Key Ontario-specific instruments include O. Reg. 102/07 (Hazardous Materials Information System), which mandates workplace training and SDS accessibility for employers. Tradespeople must also comply with the Ontario Building Code (OBC Div. B, Section 3.2.4) regarding storage limits on job sites. Provincial trade licensing (Skilled Trades Ontario) requires proof of TDG training for certain certificates (e.g., Gas Technician A). The Canada Revenue Agency (CRA) may audit vehicle logs and training records during GST/HST compliance reviews. Ignorance is not a defence: if you load, unload, or transport Class 2–9 goods—even small quantities like propane cylinders or paint thinners—you’re legally a 'consignor' or 'carrier' under TDG.
2. Required Training, Documentation & Labels
All Ontario tradespeople handling dangerous goods must complete TDG training every three years, certified by an employer or approved provider (TDG Sec. 6.2). Training records must be retained for two years post-employment. You must carry shipping documents (e.g., waybills with UN number, proper shipping name, class, and emergency contact) and ensure packages display compliant labels, placards (if >500 kg aggregate), and safety marks per TDG Part 4. Ontario Regulation 102/07 further requires workplace-specific hazard communication—meaning SDS must be accessible on-site and in vehicles. Note: Even non-commercial use (e.g., carrying 2x 4.7L gasoline cans for equipment) triggers TDG documentation if exceeding exemption thresholds (TDG Sec. 1.17). Failing to display a Class 3 flammable liquid label on a solvent container violates both TDG and OBC fire code provisions.
3. Vehicle Requirements & On-Site Storage Rules
Vehicles used by Ontario tradespeople must meet TDG Part 7 standards: secure cargo, prevent leakage, and segregate incompatible classes (e.g., acids from cyanides). Ontario’s Fire Code (O. Reg. 213/07) restricts on-site storage: e.g., no more than 200 L of Class 3 flammables in a single indoor location without a fire-rated cabinet. The Ontario Building Code (OBC 3.2.4.5) prohibits storing dangerous goods in exit corridors or near ignition sources. For mobile service vehicles, TDG requires secondary containment for liquids and ventilation for gases—especially relevant for HVAC techs transporting refrigerants (Class 2.2). Skilled Trades Ontario inspectors may verify vehicle compliance during licence renewal audits. Non-compliant storage can void insurance and trigger Ministry of Labour inspections under OHSA.
4. Penalties, Enforcement & Recordkeeping
Violations attract strict liability penalties: up to $50,000 per offence under TDG (Sec. 29) and up to $100,000 or 2 years’ imprisonment for repeat or willful breaches. Ontario’s Ministry of Labour, Immigration, Immigration and Skills Development enforces O. Reg. 102/07 through workplace inspections—and may refer cases to Transport Canada. Records required include TDG training certificates, shipping documents (retained 2 years), SDS logs, and vehicle inspection reports. CRA may cross-reference these during business audits, particularly for contractors claiming vehicle expenses. Provincial trade licences (e.g., Electrical Contractor Licence) require ongoing TDG compliance as a condition of good standing. Fines are levied per occurrence—not per day—so improper labelling on five containers equals five separate violations.

Reg. 102/07 workplace SDS logs, and prepare for Skilled Trades Ontario audits—all tailored to your trade, vehicle type, and common dangerous goods (e.g., acetylene, methanol, lithium batteries).
Get Expert Help from HandymenAIFrequently Asked Questions
Do I need TDG certification if I only transport small amounts of paint or cleaning solvents?
Yes—if quantities exceed TDG exemptions (e.g., >1 L of Class 3 flammable liquid per container, or >50 kg aggregate). Most trade-related solvents, aerosols, and adhesives fall under regulated classes. Ontario Regulation 102/07 applies regardless of quantity if used in the workplace.
Can my Ontario trade licence be suspended for TDG violations?
Yes. Skilled Trades Ontario may suspend or refuse renewal of licences (e.g., Gas Technician, Powerline Technician) for repeated TDG non-compliance, as it reflects on public safety competence under the Ontario College of Trades Transition Act, 2021.
