Greenwashing in Canada Just Became a Legal Risk

Greenwashing in Canada is no longer just a reputational concern. It has become a legal, compliance, investor, and business risk for companies that communicate environmental claims without strong evidence.

For years, companies used broad sustainability language to describe climate goals, product benefits, net zero plans, responsible sourcing, and corporate environmental performance. Terms such as “green,” “eco-friendly,” “sustainable,” “carbon neutral,” and “climate positive” appeared in marketing materials, annual reports, websites, investor decks, product labels, and recruitment campaigns.

Today, that language needs much more discipline.

Canada’s Competition Bureau has issued final guidance on environmental claims and the Competition Act, following amendments that added two provisions explicitly targeting greenwashing. These provisions require certain product environmental claims to be based on adequate and proper testing, and certain business or business activity claims to be supported by adequate and proper substantiation using an internationally recognized methodology.

That creates a new reality for Canadian companies. Sustainability communication can no longer move faster than sustainability performance.

Why Canada is tightening expectations

Consumers, investors, regulators, employees, and business partners increasingly expect companies to prove their sustainability claims. At the same time, many organizations still struggle to explain environmental progress clearly and accurately.

This creates risk.

A company may have a real sustainability strategy, but weak wording can make it appear misleading. Another company may have strong environmental initiatives, but poor data can weaken trust. A marketing team may want a bold message, while the sustainability team may know that the evidence is incomplete. Legal may see the risk only after the campaign is nearly ready.

That gap is where greenwashing risk grows.

The Competition Bureau’s final guidelines regarding environmental claims clarify how environmental claims are assessed under the Competition Act’s deceptive marketing provisions. The Bureau also notes that environmental claims are examined on a case-by-case basis and assessed on their own merits.

This means companies should not treat the rules as a reason to stay silent. Instead, they should treat them as a reason to strengthen governance, documentation, and internal review.

Real-world warning signs are already visible

Canada has already seen how environmental claims can create regulatory and reputational consequences.

The Competition Bureau states that it has taken enforcement action in environmental claims cases under the deceptive marketing practices provisions of the Competition Act, including matters involving Keurig and Volkswagen. Its consumer-facing guidance also directs readers to examples such as Keurig Canada’s settlement over coffee pod recycling claims and compensation related to Volkswagen, Audi, and Porsche emissions cases.

These examples show why environmental claims need the same level of care as other public business statements. Even when a claim sounds simple, it can carry legal and reputational consequences if it gives the wrong impression or lacks support.

The lesson for Canadian companies is clear: greenwashing risk does not start only with false claims. It can also start with claims that are too broad, too vague, too selective, or poorly substantiated.

The problem with vague sustainability language

Many greenwashing risks begin with vague language.

A claim such as “we are sustainable” may sound positive, but what does it actually mean? Sustainable compared to what? Based on which data? Across which part of the business? Over what time period?

The same issue applies to phrases such as:

• environmentally friendly
• clean
• green
• low carbon
• net zero
• climate positive
• carbon neutral
• responsibly sourced
• eco-conscious

These phrases can create confusion when they lack context. They may also create legal risk if they suggest a broader environmental benefit than the company can prove.

A stronger approach is to make claims specific. Instead of saying a product is “eco-friendly,” a company can explain the exact attribute it can support. This may include recycled content, reduced packaging weight, lower energy use, verified emissions reductions, certified sourcing, or a defined operational improvement.

Specific claims build trust. Vague claims create suspicion.

Evidence is now the heart of sustainability communication

The new reality is simple: environmental claims need evidence.

Businesses should be able to show how they reached a claim, what data supports it, and which methodology they used. Certain environmental claims about products must be based on “adequate and proper testing,” while certain claims about business activities must be supported by substantiation in line with an internationally recognized methodology.

This matters because sustainability communication often depends on complex data.

Carbon claims may require emissions calculations. Supply chain claims may require supplier due diligence. Product claims may require lifecycle information. Net zero claims may require transition plans, interim targets, and credible reporting.

For example, a company claiming emissions progress should understand whether the claim covers Scope 1, Scope 2, or Scope 3 emissions. It should also explain the baseline year, calculation method, reporting boundary, and level of assurance.

A company claiming responsible sourcing should understand supplier practices, traceability, and human rights risks whereas a company claiming net zero progress should avoid presenting ambition as achievement.

Greenwashing is becoming an investor issue

Greenwashing is often viewed as a consumer protection issue. Increasingly, however, investors also care about the quality and credibility of sustainability information.

PwC’s Global Investor Survey shows that investors are looking for companies that can protect cash flows from persistent and interconnected risks. Sustainability information plays a growing role in how many investors assess resilience, governance, risk management, and long-term value.

This matters for Canadian companies because environmental claims can influence more than consumer perception. They can affect investor confidence, lender expectations, ESG ratings, procurement decisions, and stakeholder trust.

If a company cannot support its environmental statements, the risk may move beyond marketing. It can become a governance issue.

Greenwashing is not only a marketing problem

Many companies still treat greenwashing as a communications issue. That is a mistake.

Greenwashing risk sits across the whole organization. Marketing writes the message. Sustainability provides the data. Legal reviews the claim. Procurement manages suppliers. Finance may control reporting systems. Leadership approves public commitments.

If these teams do not work together, environmental claims can become risky.

For example, a sustainability team may know that Scope 3 data remains incomplete. However, marketing may promote a broad “net zero supply chain” message. Legal may review the language after the campaign has already been developed. Leadership may approve a claim without seeing the evidence behind it.

A better process starts earlier. Companies need internal checks before claims go public. They need clear ownership, reliable data, and documented evidence.

Responsible sustainability communication requires governance, not just good writing. This is a best-practice response to the current regulatory and market environment, not a replacement for legal advice.

What Canadian companies should do now

Canadian companies can reduce greenwashing risk by creating a practical review process for environmental claims.

First, they should identify where environmental claims appear. These may include websites, social media posts, product packaging, ESG reports, investor presentations, recruitment materials, procurement documents, and sales decks.

Second, they should review high-risk language. Broad terms such as “green,” “sustainable,” “carbon neutral,” and “net zero” need careful support.

Third, they should connect each claim to evidence. If the evidence is weak, the claim should change.

Fourth, they should use recognized methodologies where relevant. For emissions, this may include the GHG Protocol. For climate targets, companies may refer to the Science Based Targets initiative. For sustainability reporting, companies may use standards such as GRI, SASB, TCFD, ISSB, CSDS 1, and CSDS 2, depending on their reporting needs.

Finally, they should train teams. Marketing, sustainability, legal, finance, procurement, investor relations, and leadership need a shared understanding of what responsible sustainability communication looks like.

A practical claim-review checklist

Before publishing an environmental claim, companies should ask:

• Is the claim specific enough?
• Can we prove it with current evidence?
• Does the claim apply to a product, service, business activity, or the whole company?
• Are we using a recognized methodology?
• Have we documented the data source?
• Does the claim explain the timeframe and boundary?
• Could a reasonable customer, investor, or stakeholder misunderstand it?
• Has legal, sustainability, and communications reviewed it?
• Are we presenting ambition as progress?
• Are we omitting important limitations?

This checklist does not remove legal risk. However, it can help companies build better internal discipline before sustainability claims become public.

Why this matters for sustainability professionals

Greenwashing risk creates a major skills gap for Canadian professionals.

It is not enough to understand sustainability strategy. Professionals must also know how to communicate sustainability performance responsibly. They need to understand reporting standards, carbon data, materiality, external assurance, stakeholder expectations, and the limits of environmental claims.

They must also know when to challenge a claim.

A sustainability professional may need to tell leadership that a statement is too broad. They may need to explain why a net zero claim requires stronger evidence. They may need to help marketing teams turn ambitious language into accurate communication.

That is not easy. But it is now essential.

Canada’s greenwashing risk is also a trust test

Companies should not respond to Canada’s greenwashing rules by avoiding sustainability communication altogether. Silence can also create risk when stakeholders expect transparency.

The goal is not to stop communicating. The goal is to communicate better.

Responsible sustainability communication should be specific, evidence-based, balanced, and transparent. It should explain progress without exaggeration. It should acknowledge limitations where needed. It should help stakeholders understand what the company has achieved, what remains in progress, and what comes next.

This approach protects trust.

It also helps companies avoid greenwashing, blue washing, SDG washing, and other forms of misleading sustainability communication.

FAQs

What is greenwashing in Canada?

Greenwashing in Canada refers to environmental claims that may be false, misleading, vague, exaggerated, or not properly supported by evidence. It can apply to products, services, business activities, climate claims, net zero goals, and sustainability communication.

Why has greenwashing become a legal risk in Canada?

Greenwashing has become a legal risk because Canada has added provisions to the Competition Act that explicitly target certain environmental claims. The Competition Bureau has also issued guidance to help businesses understand expectations around environmental claims and substantiation.

What types of claims create greenwashing risk?

High-risk claims include broad phrases such as “green,” “eco-friendly,” “sustainable,” “carbon neutral,” “net zero,” “climate positive,” and “responsibly sourced” when they lack clear evidence, methodology, or context.

How can companies reduce greenwashing risk?

Companies can reduce risk by making claims specific, using reliable data, applying recognized methodologies, documenting evidence, reviewing claims internally, and training sustainability, marketing, legal, investor relations, and leadership teams.

Is sustainability communication still important?

Yes. Companies should not stop communicating. Instead, they should communicate with more accuracy, transparency, and evidence. Responsible communication can build trust and reduce legal, investor, and reputational risk.

What sustainability leaders need next

The new anti-greenwashing landscape highlights a broader reality: sustainability professionals are expected to understand reporting standards, climate disclosures, materiality, stakeholder expectations, external assurance, and responsible communication.

These topics are no longer relevant only to sustainability teams. They increasingly influence investor relations, procurement, legal review, marketing, risk management, and executive decision-making.

The Certified Sustainability Practitioner Program – Advanced Edition, Canada Cohort 2 helps professionals develop practical expertise in sustainability reporting, materiality assessments, ESG ratings, external assurance, climate disclosure, Scope 3 emissions, net zero strategy, stakeholder engagement, and responsible sustainability communication.

The October 2026 training agenda includes key topics such as sustainability strategy, ESG ratings, stakeholder engagement, GRI, SASB, TCFD, ISSB, CSDS 1 and CSDS 2, external assurance, net zero, Scope 3, greenwashing, blue washing, SDG washing, and responsible sustainability communication.

For Canadian companies, the message is clear: sustainability claims now need substance. Professionals who understand both the strategy and the evidence behind those claims will be better prepared to lead.
