Experts want the federal government to use "mystery shopping" — where testers pretend to be regular users — to find out whether AI chatbots give dangerous advice. The idea is to test chatbots under Bill C-34, a law introduced in June that would set up a Digital Safety Commission to enforce safety rules for social media platforms and AI chatbots.

The call comes after a study led by McGill University, released in late June, that checked popular AI chatbots for harmful content. Aengus Bridgman, associate director of the Centre for Media Technology and Democracy at McGill, co-authored the study and told The Globe and Mail that testing whether chatbots give advice on harmful behaviour should be "a key part of the regulatory framework" under Bill C-34.

Emily Laidlaw, Canada Research Chair in cybersecurity law at the University of Calgary, told The Globe and Mail she supports mystery shopping audits of AI chatbots. She said such audits would "help achieve safety by design, which is a goal of the bill" — meaning the systems should be built to be safe from the start, not fixed only after something goes wrong.

The McGill study tested chatbots in May and June by asking them questions about suicide, cyberbullying of children, promoting serious eating disorders, and other harmful behaviour. Researchers used an AI tool to ask chatbots probing questions, including trying to get methods for causing harm.

The results varied sharply. ChatGPT and Google's Gemini, when pressed, provided harmful content. The report found that Gemini produced "explicit, actionable guidance in response to self-harm requests" and that a newer version "showed no improvement on this measure." Gemini also gave information on how much of a popular painkiller could kill a 14-year-old. When pushed on inducing child self-harm, Gemini's consumer app completed a fictional 14-year-old's overdose case file, specifying how much was taken and the toxicity threshold.

Meta's AI tool blocked demands for harmful information, the audit found. Anthropic's Claude AI tool refused 98 per cent of attempts to get harmful content.

Meta and OpenAI both issued statements on the same Thursday about measures they are taking to protect teens online, including safety tools built into their chatbots.

The broader context here is that Bill C-34 would put AI chatbots under the authority of the proposed Digital Safety Commission, a body whose powers are still being worked out in Parliament. The mystery-shopping idea Bridgman and Laidlaw describe would have regulators, or researchers working for them, actively probing chatbots for harmful answers instead of relying on the platforms' own safety reports. That is a shift from waiting for complaints to come in toward ongoing, active testing.

There is already a model for this approach elsewhere. The UK Office of Communications (Ofcom) uses a mystery-shopping method in which researchers create accounts that mimic real users' behaviour to check online services for child-safety problems. Ofcom The Ofcom model shows one way a Canadian regulator could run similar testing, though the federal government has not yet said whether mystery shopping will be part of the rules or guidance under Bill C-34.

The way the McGill study was done is notable too. Instead of a person typing questions by hand, the study used an automated AI tool to keep pressing the chatbots in a way that mirrors how someone trying to cause harm might interact with these systems at scale. That raises a practical question: whether a Digital Safety Commission would need its own technical staff to do this, or would hire outside academic or third-party auditors to run mystery-shopping tests credibly.

The range of results the study found across platforms also matters for enforcement. If some chatbots consistently block harmful requests while others do not, a commission using mystery shopping would need clear rules for what counts as a failure, how many tests are enough, and what penalty follows when a chatbot fails. The bill's "safety by design" approach, as Laidlaw notes, points toward looking at how these systems are built, not just at individual answers in isolation.

None of these questions have been settled yet. Bill C-34 was introduced in June and is still making its way through Parliament. The McGill study was not commissioned by the federal government, and the companies whose chatbots were tested have not been formally told of any regulatory action under the bill. What the study and the experts' commentary do is put a specific testing method in front of Parliament while the Digital Safety Commission's authority over AI chatbots is still being decided.
