Summary

The Transportation of Dangerous Goods Act regulates the handling, offering for transport, and transportation of hazardous materials across Canada by road, rail, air, and marine modes. As Canada’s energy system transitions toward low-carbon fuels such as hydrogen, biofuels, ammonia, and carbon dioxide for CCUS, the TDGA has increasing relevance for climate-related infrastructure and supply chains. The Act establishes classification, packaging, documentation, training, and emergency response requirements, enforced through inspections and penalties. Compliance is mandatory for companies involved in transporting fuels, chemicals, and energy-related materials, making the TDGA a foundational safety and risk-management law for net-zero technologies and logistics.

  • The framework increasingly applies to low-carbon fuels and CCUS-related materials

Penalties for Non-Compliance

  • Significant fines and imprisonment for serious violations

  • Administrative penalties and compliance orders may be issued
