AODA: what Ontario requires for accessible web content and documents
Under the Accessibility for Ontarians with Disabilities Act and its Integrated Accessibility Standards Regulation, the Ontario public sector and organizations with 50 or more employees must make their public websites and web content — including posted documents — conform to WCAG 2.0 Level AA. That obligation has applied to all public web content since January 1, 2021.
The law
What does the AODA require for websites and documents?
The AODA's Information and Communications standard, part of the Integrated Accessibility Standards Regulation (O. Reg. 191/11), requires designated public sector organizations and large organizations to make their public internet websites and web content conform to WCAG 2.0 Level AA. Since January 1, 2021 that requirement covers all public web content, documents included.
Two success criteria are carved out — 1.2.4 (live captions) and 1.2.5 (pre-recorded audio descriptions) — and the requirement applies to websites and to web content published after January 1, 2012. A PDF posted on a covered organization's public site is web content, not an exception to it.
Coverage
Who must comply with the AODA web accessibility rules?
The WCAG 2.0 AA website requirement applies to the Government of Ontario and the Legislative Assembly, designated public sector organizations — municipalities, universities, colleges, school boards, hospitals — and private-sector and non-profit organizations with 50 or more employees in Ontario. Smaller organizations carry other AODA obligations, but not the website standard.
| Organization | WCAG 2.0 AA website standard | Accessibility compliance report |
|---|---|---|
| Government of Ontario and the Legislative Assembly | Yes | Every year |
| Designated public sector organizations: municipalities, universities, colleges, school boards, hospitals, transit | Yes | Every 2 years |
| Businesses and non-profits with 50 or more Ontario employees | Yes | Every 3 years |
| Businesses and non-profits with 20 to 49 Ontario employees | No | Every 3 years, customer service standard only |
| Businesses and non-profits with fewer than 20 Ontario employees | No | Not required |
Two numbers, two duties: the website standard starts at 50 Ontario employees, the report at 20. A 30-person Ontario business owes a filing without owing full WCAG conformance.
An employee-count axis with two bands. The compliance-report duty starts at 20 Ontario employees; the WCAG 2.0 AA website standard starts at 50. Under 20: neither duty. 20 to 49: a report, no website standard. 50 and up: both.
Employee counts are Ontario counts, and obligations attach per organization — a national company with 60 Ontario employees is covered for its public web content.
Documents
How does the AODA apply to PDFs and other documents?
A document posted on a public website is web content, so PDFs, Word files and presentations published since January 1, 2012 on a covered organization's site fall under the WCAG 2.0 Level AA requirement. Separately, every obligated organization must provide accessible formats and communication supports on request, in a timely manner and at no extra cost.
In practice that reaches the same document set as the US rules: council and board packets, bylaws and policies, forms, plans, reports and newsletters. The technical work is the same too — tags, reading order, alternative text, titles, language and labeled form fields — which is why remediating to WCAG 2.1 AA and PDF/UA comfortably satisfies Ontario's 2.0 AA bar.
Two duties, and DocoMatic serves one: we remediate and verify the documents you publish. Accessible formats on request — braille, large print, tactile — are a separate duty we do not produce; that process stays yours.
Reporting
What is the AODA compliance report, and when is it due?
Covered organizations must file recurring accessibility compliance reports with the Ontario government confirming they meet their AODA obligations. Designated public sector organizations report every two years, and businesses and non-profits with 20 or more employees report every three years. A director or senior officer certifies each report, and false or missed reports carry penalties.
The cycles are in the thresholds table. Currently, the next business and non-profit report is due December 31, 2026; the last designated public sector report was due December 31, 2025.
The report is a self-attestation — which is exactly why document evidence matters. An organization that certifies web accessibility compliance while its site hosts hundreds of untagged PDFs is certifying something its own inventory would contradict; a per-file verification trail makes the attestation defensible.
On the left, an accessibility compliance report certified as complete and accurate, with a signature line. On the right, the organization's public site inventory: untagged PDFs, missing alternative text, no reading order. A not-equal sign sits between them. The point is the mismatch, not a consequence.
Before you certify, know what you publish. Scan your public site free — a few minutes, no account — and you will have the document count and failing share the attestation implicitly claims.
Comparison
How does the AODA compare with US and federal Canadian rules?
The AODA governs Ontario and cites WCAG 2.0 Level AA, in force for public web content since 2021. The Accessible Canada Act covers federally regulated organizations through accessibility plans rather than a single web deadline. In the US, the ADA Title II rule requires the newer WCAG 2.1 Level AA by April 2027 or April 2028.
| AODA (Ontario) | Accessible Canada Act | ADA Title II (US) | |
|---|---|---|---|
| Covers | Ontario public sector; 50+ Ontario employees | Federally regulated organizations | US state and local governments |
| Standard | WCAG 2.0 AA, less 1.2.4 and 1.2.5 | Plans and progress reports; SOR/2025-255 adds CAN/ASC-EN 301 549 duties | WCAG 2.1 AA |
| In force | Since January 1, 2021 for all public web content | Ongoing; federal public sector web pages from December 5, 2027, documents from December 5, 2028 | April 26, 2027 or April 26, 2028, by population |
| The obligation | Conformance plus recurring compliance reports | Published plans plus progress reports | Conformance by a date |
Organizations operating on both sides of the border — universities, transit agencies, health networks, vendors — should remediate once to the strictest common bar: WCAG 2.1 Level AA plus PDF/UA satisfies the AODA, the ACA's plan commitments and the US rules with a single pipeline.
The plan
What should an Ontario organization do now?
The website requirement is already in force, so treat the backlog as due, not upcoming. Inventory the documents on your public sites, prioritize the ones residents and customers currently use, remediate them to WCAG standards with a verification report per file, and be ready to honour accessible-format requests on a defensible timeline.
Inventory: enumerate every PDF and Office document on your public domains, including files posted since 2012. Scan your site free — no account, a few minutes.
Prioritize: forms, agendas and documents in active use come first. How risk ranking works.
Remediate and verify: bring files to WCAG conformance and keep the per-file verification report. Bulk remediation · What a verification report contains.
Prepare for requests: have a process to deliver accessible formats and communication supports promptly. DocoMatic does not produce braille or large print; this step is yours.
Does a 30-employee Ontario company have to meet WCAG?
The website standard applies at 50 or more Ontario employees, so a 30-employee company is not required to meet WCAG 2.0 AA on its site. It still has AODA obligations — accessible customer service, and accessible formats and communication supports on request — and if it serves the public sector, procurement often demands accessible documents anyway.
Does the AODA require WCAG 2.0 or WCAG 2.1?
WCAG 2.0 Level AA, excluding success criteria 1.2.4 (live captions) and 1.2.5 (pre-recorded audio descriptions). WCAG 2.1 includes every 2.0 criterion, so remediating documents to 2.1 AA — the bar US rules now set — and PDF/UA automatically satisfies Ontario's requirement as well.
Do documents published before 2012 have to be remediated?
The website requirement applies to web content published after January 1, 2012, so older files sit outside it — until someone needs one. Accessible formats must be provided on request for the information an organization holds, so a frequently requested 2009 document is often worth remediating proactively; a ranked inventory of your public site finds them.
Does the AODA website requirement cover intranets?
The WCAG 2.0 AA requirement in the Integrated Accessibility Standards Regulation applies to public internet websites and their content. Internal systems are not under that provision, but employee-facing obligations elsewhere in the AODA — accessible formats, individualized workplace information — still reach internal documents when an employee needs them.
What happens if an organization does not comply with the AODA?
Ontario can audit organizations, issue orders, levy administrative penalties and prosecute — for corporations, fines of up to $100,000 CAD per day for the most serious violations. In practice the first pressure point is the compliance report: directors certify it, and a certification contradicted by an inaccessible document backlog is a governance problem, not just a technical one.
What about Quebec?
Quebec's Standard sur l'accessibilité des sites Web (SGQRI 008) applies to Quebec public bodies, separately from the AODA and the ACA; this guide does not cover it. Start from our page for Canadian organizations and confirm Quebec obligations with counsel.
