EN 301 549 vs ACA
EN 301 549 (EN 301 549 — Accessibility requirements for ICT products and services, European Union (harmonised standard), 2014 (v3.2.1 current)) and ACA (Accessible Canada Act, Canada — federally regulated entities, 2019) 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 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.
Maintainer
ETSI / CEN / CENELEC
Jurisdiction and enforcement
European Union (harmonised standard). Referenced by EAA and Web Accessibility Directive.
What is ACA?
The Accessible Canada Act (ACA, 2019) requires federally regulated entities — federal government, banks, telecom, broadcasting, transportation — to identify, remove and prevent accessibility barriers, with the explicit goal of "a Canada without barriers by 2040" and detailed regulations layered on top including the ICT regulations referencing EN 301 549.

EN 301 549 vs ACA — the key differences
The principal difference is jurisdictional: EN 301 549 applies in European Union (harmonised standard), while ACA applies in Canada — federally regulated entities. EN 301 549 is maintained by ETSI / CEN / CENELEC; ACA is maintained by Accessibility Standards Canada. 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
EN 301 549 covers: Web content, Non-web documents (PDF, EPUB), Software (native apps, OSes), Hardware (kiosks, devices), Documentation, ICT support services. ACA covers: Federally regulated workplaces, Federal services (incl. digital), Federally regulated transportation and telecom.
Penalties
EN 301 549: Inherited from referencing law (WAD or EAA per member state). ACA: Administrative monetary penalties up to C$250,000 per violation.
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 EN 301 549 and ACA 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 European Union (harmonised standard) and have no cross-border procurement exposure, you may only need EN 301 549. The same applies in reverse for ACA. 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 EN 301 549 stricter than ACA?
Neither standard is uniformly "stricter" — they cover different regulatory domains. EN 301 549 is more prescriptive about web content; ACA about federally regulated workplaces. For organisations exposed to both, a unified WCAG 2.2 AA baseline typically satisfies the technical requirements of both.
Can a single audit satisfy EN 301 549 and ACA?
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 EN 301 549?
European Union (harmonised standard). Referenced by EAA and Web Accessibility Directive.
Which jurisdictions enforce ACA?
Canada — federally regulated entities. Accessibility Commissioner; CRTC for telecom; CTA for transportation.
What happens if I am not compliant with EN 301 549?
Inherited from referencing law (WAD or EAA per member state)
What happens if I am not compliant with ACA?
Administrative monetary penalties up to C$250,000 per violation
