Section 508 vs AODA
Section 508 (Section 508 of the Rehabilitation Act, United States — federal government and federal contractors, 1998 (2017 Refresh)) and AODA (Accessibility for Ontarians with Disabilities Act, Ontario, Canada, 2005) 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 Section 508?
Section 508 of the Rehabilitation Act requires US federal agencies, federal contractors, and recipients of federal funds to make their information and communications technology (ICT) accessible to people with disabilities, with conformance benchmarked against WCAG 2.0 Level AA via the 2017 Refresh.

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.

Section 508 vs AODA — the key differences
The principal difference is jurisdictional: Section 508 applies in United States — federal government and federal contractors, while AODA applies in Ontario, Canada. Section 508 is maintained by US Access Board; AODA is maintained by Government of Ontario. 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
Section 508 covers: Federal-agency websites and applications, Federal-contractor ICT, ICT procured with federal funds. AODA covers: Public-facing websites and web content, Documents (PDF/Word), Customer-service communications.
Penalties
Section 508: Procurement disqualification. AODA: C$50,000/day for individuals or unincorporated organisations.
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 Section 508 and AODA 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 United States — federal government and federal contractors and have no cross-border procurement exposure, you may only need Section 508. The same applies in reverse for AODA. 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 Section 508 stricter than AODA?
Neither standard is uniformly "stricter" — they cover different regulatory domains. Section 508 is more prescriptive about federal-agency websites and applications; AODA about public-facing websites and 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 Section 508 and AODA?
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 Section 508?
United States — federal government and federal contractors. GSA, agencies, US Court of Federal Claims.
Which jurisdictions enforce AODA?
Ontario, Canada. Accessibility Directorate of Ontario.
What happens if I am not compliant with Section 508?
Procurement disqualification Contract termination or modification Bid protests at GAO and US Court of Federal Claims Reputational and downstream civil-rights exposure under Sections 501 and 504
What happens if I am not compliant with AODA?
C$50,000/day for individuals or unincorporated organisations C$100,000/day for corporations
