The duty to accommodate is not unlimited. Every Canadian human rights statute recognizes that employers, service providers, and housing operators are entitled to stop short of perfection when the cost of accommodation becomes too great. This stopping point is called undue hardship, and understanding where it lies is essential for any business owner, sole proprietor, or non-profit operator who must balance their legal obligations against the practical realities of running an organization. The concept exists because Canadian human rights law has never demanded that accommodation come at any price. Instead, it requires a reasonable effort, pursued in good faith, up to the point where continuing would cause harm that the law considers unreasonable to impose on the accommodating party.
The foundation of undue hardship appears in every provincial and territorial human rights code, as well as in the Canadian Human Rights Act, which governs federally regulated employers and service providers. In British Columbia, the Human Rights Code explicitly references undue hardship as the limit of the duty to accommodate. Alberta's legislation uses similar language, as does the Saskatchewan Human Rights Code, the Ontario Human Rights Code, and the federal statute. Quebec presents a slightly different framework because its Charter of Human Rights and Freedoms operates within a civil law system governed by the Civil Code of Quebec, but the concept of undue hardship still applies, interpreted through the lens of proportionality and the balancing of rights that characterizes Quebec jurisprudence. Across all jurisdictions, the principle remains consistent: accommodation must be provided unless doing so would cause hardship that is undue, meaning hardship that exceeds a reasonable threshold.
