Binding law — in force
State in every publicly advertised job posting that AI is used to screen, assess or select applicants (Ontario, ESA s. 8.4)
From 2026-01-01, Ontario's Employment Standards Act, 2000 s. 8.4 requires every employer (including a prospective employer) who advertises a publicly advertised job posting and uses artificial intelligence to screen, assess or select applicants for the position to include in the posting a statement disclosing that use; O. Reg. 476/24 defines AI as a machine-based system that infers from inputs how to generate outputs such as predictions, content, recommendations or decisions, defines publicly advertised job postings (excluding general recruitment campaigns, help-wanted signs, internal-only postings and work outside Ontario) and exempts employers with fewer than 25 employees. Postings must be kept for three years after they are taken down (s. 15(7.1)). Detect posting-publishing code in a pipeline that ranks or scores candidates, with no AI-use statement.
