Top pitfalls HR leaders must avoid when deploying AI in HR

The rollout of artificial intelligence (AI) tools across Canadian HR departments is accelerating, but governance isn’t keeping pace. According to Statistics Canada’s Analysis on expected use of artificial intelligence by businesses in Canada, 19.2 per cent of Canadian businesses were actively using AI as of mid-2026. Yet nearly four in five Canadian workers are already reaching for it at work – and most of them are doing it without employer oversight. When it comes to recruitment, performance, benefits, and compliance, that gap is where liability can accumulate for human resources (HR) leaders – particularly in the sensitive area around HR applications and data.

While the StatCan data showed a relatively small proportion of businesses actively using AI, that number has more than tripled from 6.1 per cent two years earlier. And a 2025 study of shadow AI by IBM Canada found that 79 per cent of Canadian workers use AI at work, but only one in four are using enterprise-grade tools. The remainder are relying largely on free, public platforms – feeding organizational data into systems employers don’t control.

These aren’t abstract governance concerns, they’re active risk exposures that, when they surface in HR’s own AI use, can be perilous. Here are some key pitfalls for HR leaders to avoid when deploying AI in their HR functions.

The compliance trap

No area of HR work carries more legal exposure when delegated to AI than employment standards and compliance. Canadian employment law varies significantly by province, and the language used in termination letters, policies, and employment contracts can determine the outcome of a legal dispute.

The regulatory precision required of HR professionals makes Sheila Thomson, HR Director at EastGen in Guelph, Ont., wary of AI-generated outputs. "Because HR is highly governed and legislated, a word can have significant difference," says Thomson, adding that while AI responses on compliance questions have improved over the past year, she still verifies all output against primary sources before anything enters a document.

Her caution is well-placed. Katie Thibeault, HR Manager at Cognition+ in London, Ont., puts the risk plainly: "I wouldn’t use it unchecked when it comes to things like employment legislation. It varies so much,” says Thibeault. “There are so many nuances there. It might sound like an employment lawyer, but it isn't."

Thibeault also raises a less-obvious exposure: AI note-taking tools in meetings with employment counsel. "There's a third party in there, and where are those notes being stored?” she says. “The more parties that are involved, it can take away from that confidentiality piece."

The regulatory environment is tightening on this front. Ontario's Working for Workers Four Act, which came into force on Jan. 1, 2026, requires employers to disclose when AI is used to screen or select job applicants. Quebec's Law 25 (Section 12.1) goes further, requiring organizations to notify individuals when decisions affecting them are made exclusively through automated processing, and to offer an opportunity for human review. Bill C-36 – the Protecting Privacy and Consumer Data Act (PPCDA) – was tabled in the federal House of Commons on June 15, 2026, and, if passed, would impose fines of up to $25 million or five per cent of global revenue for violations.

When chatbots dig a hole

The risks playing out in customer-facing AI are now migrating inside organizations. As HR leaders explore using AI-powered chatbots to handle routine employee inquiries on benefits, leave, and policy, two Canadian cases show what is at stake.

In June 2026, a BMW Toronto dealership chatbot offered a customer more than $27,000 to buy back his vehicle – an amount that didn’t reflect the car's actual value and was only reinstated after news media covered the matter. An Air Canada chatbot case, decided in 2024, set a more significant precedent: a tribunal found the airline legally liable for incorrect information its chatbot provided to a customer, ruling that AI responses can be binding on the organization. When AI chatbots get it wrong inside a business, the question of who answers for it will ultimately end up on the HR leader’s desk.

Translated into the HR context – where a chatbot might incorrectly state parental leave entitlements, statutory termination pay, or disciplinary procedures – the liability is direct. It’s essential that any chatbot deployed for HR queries is drawing on verified, up-to-date internal policy documents, its outputs carry appropriate disclaimers, and its logs can be audited, according to Thibeault. "It's really important that HR, who may be supporting that AI chatbot, understands where the chatbot is pulling information from and ensuring those sources are accurate," she says.

A practical approach to avoiding the pitfalls from AI chatbots serving at a first contact for HR functions is to make it clear that it’s a tool and not replacing the people element, says Helen Ashton, Vice President of People, Culture and Customer Experience at Grand & Toy in Toronto. “It's making it very, very clear that this is not to replace that collaboration, that internal communication, and the partnership with others,” says Ashton. “This is a tool that could help you."

The data privacy snare

For many Canadian HR leaders, the most persistent barrier to AI adoption is not the technology itself, it’s the risk of data leaving the building. HR professionals are increasingly aware that AI-driven errors carry real financial consequences for employers, and data exposure is among the most costly.

"If the organization isn't going to invest in a corporate [AI] account where we have an extra level of confidentiality, that's where I have hesitation," says Thomson.

Thibeault agrees on the data risk: "Once you put that out into an external large language model (LLM), you can't take that back," she says.

Unstructured AI use is already surfacing in Canadian workplace disputes, according to employment lawyers, even before the formal regulatory framework has fully caught up.

A gender gap in a female-dominated profession

A Statistics Canada study published in June 2026, drawing on the Canadian Survey on Working Conditions and titled Workplace artificial intelligence use: A profile of sociodemographic and job characteristics, found that while women and men report equal overall rates of generative AI use at work (22 per cent each), that parity disappears once occupation, industry, and education are accounted for.

After controlling for those factors, Canadian men were 15 per cent more likely than women to report using generative AI at work — a statistically significant gap. In health care and social assistance, a sector that employs a large share of Canadian women, 21 per cent of men reported using generative AI compared to 13 per cent of women. That pattern is consistent with a Deloitte survey, Women and Generative AI, which found a persistent gap between men and women globally — 44 per cent of men versus 33 per cent of women in 2024 — even as women's adoption rate has been accelerating.

The implication and potential pitfall for HR is, if the women who make up the majority of the HR profession are receiving less organizational support to adopt AI tools safely, the adoption gap won’t close on its own – and the downstream effects on professional development, pay, and influence are real.

Responsible AI adoption in HR

None of this argues against AI in HR. The efficiency gains in engagement survey analysis, policy drafting, benefits administration, and workforce data processing are well-documented and real. The question is whether the governance structures are in place to support them.

Thibeault believes that it’s essential for HR leaders to ensure that they have an enterprise-grade platform with clear data residency and access controls; a usage policy that’s reviewed regularly as tools evolve; human review of any AI output entering a legal document, performance record, or compliance communication; and structured auditing of chatbot responses before they reach employees.

"AI usage policies are important," Thibeault says. "And revisiting that regularly, just because it is changing so quickly."

The technology isn’t going away. But in a profession as legally regulated and as human-centred as HR, deploying it without governance in place isn’t efficiency. It’s walking into a trap.

“AI is just another tool, this is not a replacement for anything,” says Ashton. "There are no answers just yet. I wish there was a playbook, but I don't think there is one."
