When a complainant establishes what tribunals call a prima facie case of discrimination, something important happens in the legal proceeding: the burden shifts to the employer. This shift is not merely procedural. It fundamentally changes who must prove what, and it places the responding party in a position where silence or inaction will almost certainly result in an adverse finding. For business owners, sole proprietors, and non-profit operators across Canada, understanding this shifted burden is essential because it defines the terrain on which an employer must mount a defence. The question is no longer whether something discriminatory occurred but whether the employer can justify the conduct, policy, or decision that led to the complaint.
Canadian human rights law operates on the principle that once discriminatory treatment is shown, the onus falls to the party with the power and information to explain. Employers are presumed to have access to the reasoning behind their decisions, the documentation supporting those decisions, and the operational context in which they were made. This is why the law places the evidentiary burden on employers at this stage. A complainant who has shown differential treatment connected to a protected ground has done their part. Now the employer must respond with more than denials. The response must be substantive, evidence-based, and grounded in principles that Canadian human rights legislation recognizes as legitimate.
