AODA vs EN 301 549
AODA (Accessibility for Ontarians with Disabilities Act, Ontario, Canada, 2005) and EN 301 549 (EN 301 549 — Accessibility requirements for ICT products and services, European Union (harmonised standard), 2014 (v3.2.1 current)) are two of the most-referenced accessibility frameworks in digital compliance. This guide compares them side by side — jurisdiction, scope, conformance approach, penalties, and how a single audit can cover both simultaneously.
What is AODA?
The Accessibility for Ontarians with Disabilities Act (AODA) is a 2005 Ontario law that mandates accessibility for the public, private, and not-for-profit sectors operating in Ontario — including a digital requirement that public-facing websites conform to WCAG 2.0 Level AA.
Maintainer
Government of Ontario
Jurisdiction and enforcement
Ontario, Canada. Accessibility Directorate of Ontario.
What is EN 301 549?
EN 301 549 is the harmonised European standard for digital accessibility, maintained jointly by ETSI, CEN, and CENELEC, that incorporates WCAG 2.1 AA for web and mobile content and adds requirements for hardware, software, documentation and support — and is the technical reference for both the European Accessibility Act and the Web Accessibility Directive.

AODA vs EN 301 549 — the key differences
The principal difference is jurisdictional: AODA applies in Ontario, Canada, while EN 301 549 applies in European Union (harmonised standard). AODA is maintained by Government of Ontario; EN 301 549 is maintained by ETSI / CEN / CENELEC. The standards differ on scope, conformance grading, and penalty structure — but a well-designed accessibility programme can satisfy both simultaneously by adopting the strictest applicable requirement and cross-mapping findings.
Scope
AODA covers: Public-facing websites and web content, Documents (PDF/Word), Customer-service communications. EN 301 549 covers: Web content, Non-web documents (PDF, EPUB), Software (native apps, OSes), Hardware (kiosks, devices), Documentation, ICT support services.
Penalties
AODA: C$50,000/day for individuals or unincorporated organisations. EN 301 549: Inherited from referencing law (WAD or EAA per member state).
How to comply with both at once
Adopt the stricter applicable conformance level — typically WCAG 2.2 Level AA — as your engineering baseline. Audit against that baseline once, then cross-map findings to both AODA and EN 301 549 specific requirements. A single Accessibility Conformance Report (ACR) using VPAT 2.5 INT can document both.
When you might need just one
If you operate exclusively in Ontario, Canada and have no cross-border procurement exposure, you may only need AODA. The same applies in reverse for EN 301 549. For organisations selling cross-border, into the EU or US public sector, the safer default is to plan to both simultaneously.

FAQ
Frequently asked questions
Cited answers. Sourced. Updated as standards and case law change.
Is AODA stricter than EN 301 549?
Neither standard is uniformly "stricter" — they cover different regulatory domains. AODA is more prescriptive about public-facing websites and web content; EN 301 549 about web content. For organisations exposed to both, a unified WCAG 2.2 AA baseline typically satisfies the technical requirements of both.
Can a single audit satisfy AODA and EN 301 549?
Yes. Both standards ultimately reference WCAG-aligned criteria. A combined audit with cross-mapped findings can produce documentation acceptable to both regulators.
Which jurisdictions enforce AODA?
Ontario, Canada. Accessibility Directorate of Ontario.
Which jurisdictions enforce EN 301 549?
European Union (harmonised standard). Referenced by EAA and Web Accessibility Directive.
What happens if I am not compliant with AODA?
C$50,000/day for individuals or unincorporated organisations C$100,000/day for corporations
What happens if I am not compliant with EN 301 549?
Inherited from referencing law (WAD or EAA per member state)
