Summary

Bill C-59 is a large Canadian omnibus bill introduced in 2023 to implement economic and regulatory measures from the federal Fall Economic Statement. The bill includes significant sustainability-related provisions, notably amendments to combat greenwashing, new transparency rules for environmental claims made by businesses, and expanded oversight powers for regulators to address deceptive environmental marketing practices. Bill C-59 also implements fiscal, tax, and industrial-policy measures tied to Canada’s clean-economy strategy, including investment tax credits for clean energy, clean technologies, and sustainable manufacturing. It aims to strengthen consumer protection, enhance market integrity for environmental claims, and support Canada’s transition to a low-carbon, innovation-driven economy.

Details

Jurisdictions
  • Canada
Exemptions

Bill C-59 is a binding federal Act, making its provisions mandatory once in force under Canadian law.

Criteria:

Applies to businesses operating in Canada that make environmental or sustainability-related claims, as well as companies seeking eligibility for clean-economy incentives, investment tax credits or other fiscal measures under the Act.

Also applies to federal regulators, including the Competition Bureau, which oversees substantiation of environmental claims under the amended Competition Act.

Exemptions and Flexibility:

Not every provision applies universally, as Bill C-59 is an omnibus Act with sections coming into force on different timelines (so businesses may be subject to only certain parts depending on their sector, activities or claim types).

Transitional flexibility may apply as regulators issue guidance for environmental-claim substantiation, allowing time for companies to adapt compliance systems.

Eligibility for clean-economy tax credits contains specific criteria, and businesses that do not meet technical requirements are exempt from obligations but also cannot claim incentives.

What’s Required

Businesses must:

  • Review environmental claims to ensure substantiation and compliance with amended Competition Act provisions.

  • Identify eligibility for new clean-technology tax credits and restructure investment strategy accordingly.

  • Monitor regulatory guidance from the Competition Bureau and federal agencies for implementation timelines and compliance expectations.

Important Deadlines

  • 20 June 2024: Royal Assent of Bill C-59.

  • Phased rollout of clean-tech incentives and claim-substantiation rules (to be specified in regulations and guidance).

  • Businesses should anticipate enforcement guidance from the Competition Bureau in 2024–2025.

Current Status

Bill C-59 is in force as of June 2024. Implementation is underway, but regulatory details—especially for anti-greenwashing enforcement remain under development. Some industries are already adjusting due to regulatory uncertainty.

Penalties for Non-Compliance

  • For anti-greenwashing: amendments to the Competition Act allow competition-law enforcement, which may include fines, stop-orders, or corrective actions (exact penalty structure will follow regulatory guidance).

  • Tax-credit misuse or incorrect claims may trigger repayment or legal penalties under tax or regulatory law.

  • Regulatory non-compliance may result in scrutiny, reputational damage, and increased enforcement activity.

Examples of Known Violations

  • The Pathways Alliance (Canadian oil-sands producers) removed environmental-claims content, citing “uncertainty” over the new rules.

  • Given the novelty of enforcement under Bill C-59, publicly-reported penalty cases are still limited.

Conclusion

Bill C-59 marks a major evolution in Canada’s approach to sustainable development, corporate environmental responsibility, and clean-economy investment. While many details remain to be clarified via regulation, businesses must act now to update claims, reassess investment strategy, and align with emerging enforcement expectations.
