In the first half of 2026, there have been more AI-related securities class action filings in the United States than in all of 2025, representing the highest number of such claims in the last five years1. Many of these class actions involve allegations of “AI washing”—a term used to describe issuers alleged to have exaggerated or misrepresented the role, capabilities, or impact of AI in their business. While Canada has not yet seen a similar spike, the growing trend south of the border may be a preview of what is to come. To mitigate this risk, Canadian issuers should ensure that their disclosures accurately reflect their use of AI and avoid exaggerated, imprecise, or unsupported claims.
The term “AI washing” comes from “greenwashing,” which describes the practice of overstating or misrepresenting an issuer’s environmental initiatives or the environmental benefits of its products and services. Like greenwashing, AI washing occurs when companies misrepresent or exaggerate the role, capabilities, or impact of AI in their business.
AI washing allegations can take various forms. The classic case involves allegations that an issuer has falsely claimed to be deploying or developing AI technology, or has exaggerated its AI capabilities. Other cases involve allegations that an issuer has misrepresented the impact of its AI strategy on key business metrics, including financial performance.
There has been a recent spike in AI washing securities class actions in the United States. The following are examples of allegations from recent claims:
Canada has not yet seen the same spike in AI washing class actions, though the US experience may be a preview of what is to come. In one recent Canadian case, a plaintiff commenced a proposed class action involving AI-related disclosure. The allegations include that the company failed to disclose material facts relevant to its AI products and services, and thereby negligently reported its financial performance9. The claim has not been certified.
Further, in December 2024, the Canadian Securities Administrators issued guidance cautioning issuers that AI washing “may be misleading to the public or constitute a misrepresentation, as defined by securities legislation”, and warned against “vague and unsubstantiated statements” about AI10.
As with greenwashing claims, a key issue in AI washing cases may be whether the alleged misrepresentation is sufficiently material to investors. While AI has become a significant market theme, it remains to be seen how Canadian courts will assess whether statements about an issuer’s AI capabilities or competitive advantages would reasonably be expected to have a significant effect on the market price or value of the issuer’s securities.
The rapidly evolving nature of AI may also complicate courts’ assessments of alleged misrepresentations. Given the uncertainty surrounding AI capabilities and the value that AI may ultimately generate, courts and regulators may face challenges in distinguishing between statements that were misleading when made, and forward-looking statements or expectations that simply failed to materialize. More broadly, AI washing claims may also raise novel questions about how continuous disclosure obligations intersect with a rapidly evolving technological landscape.
The recent wave of AI washing litigation in the United States serves as a reminder that AI-related disclosure requires the same rigour as any other public-facing disclosure. As AI becomes increasingly prevalent in business operations, scrutiny of AI-related statements will intensify. Canadian issuers should ensure their AI-related communications are accurate and balanced, avoiding vague buzzwords and unsupported claims about the sophistication, performance, or revenue impact of their AI technology.
