Accessibility for Ontarians with Disabilities Act (AODA)
The Accessibility for Ontarians with Disabilities Act (AODA) was passed in 2005 with the goal of making Ontario accessible to persons with disabilities by January 1, 2025. It is one of the most comprehensive provincial accessibility laws in Canada and the one most directly affecting day-to-day digital work for Ontario organizations.
Who must comply?
The AODA applies to all organizations in Ontario with one or more employee, including:
- Private sector businesses (for-profit and non-profit)
- Ontario provincial government ministries, agencies, and Crown corporations
- Municipalities and local boards
- Universities, colleges, and school boards
- Hospitals and health care organizations
The Integrated Accessibility Standards Regulation (IASR)
Web accessibility requirements come from Ontario Regulation 191/11, the Integrated Accessibility Standards Regulation (IASR). The IASR consolidates standards for:
- Customer Service — how you serve people with disabilities
- Information and Communications — websites, digital documents, feedback processes
- Employment — recruitment, accommodation, performance management
- Transportation — public transit providers
- Design of Public Spaces — outdoor paths, service counters, etc.
For digital teams, the Information and Communications standard is the key section.
Web content requirements
WCAG 2.0 Level AA
The IASR requires that all new and significantly refreshed public-facing websites and web content conform to WCAG 2.0 Level AA, with two exceptions:
| Exception | Details |
|---|---|
| Live captions | Organizations must make reasonable efforts; if not possible, provide alternative access |
| Pre-recorded audio descriptions | Not required for content published before January 1, 2012 |
Compliance timelines
| Organization type | WCAG 2.0 Level A | WCAG 2.0 Level AA |
|---|---|---|
| Government of Ontario (large) | January 1, 2012 | January 1, 2016 |
| Large private/non-profit (50+ employees) | January 1, 2014 | January 1, 2021 |
| Small private/non-profit (1–49 employees) | January 1, 2014 | January 1, 2021 |
Other digital obligations
Beyond WCAG, the IASR requires Ontario organizations to:
- Provide accessible formats and communication supports on request (e.g., large print, Braille, audio, accessible digital formats)
- Provide accessible formats in a timely manner and at no extra cost
- Post an accessibility feedback process on their website
- Publish an accessibility plan (large organizations) that is updated every 5 years
- Ensure feedback forms on websites are accessible
Accessible documents
Existing documents (PDFs, Word files) must be made accessible upon request. New documents intended for public use should be accessible from the start. This includes:
- Forms with proper field labels and tab order
- PDFs with tagged structure, alt text, and reading order
- PowerPoint files with slide titles, alt text, and logical reading order
Enforcement
LeadershipThe AODA is enforced by the Accessibility Directorate of Ontario, part of the Ontario government.
Compliance reporting
Organizations must file accessibility compliance reports to demonstrate they are meeting IASR requirements. Filing periods:
| Organization type | Filing schedule |
|---|---|
| Ontario government | Every year |
| Large organizations (50+ employees) | Every 3 years |
| Small organizations with 20+ employees | Every 3 years |
| Organizations with fewer than 20 employees | Not required to file |
Penalties
| Violation type | Maximum penalty |
|---|---|
| Individuals | $50,000 per day |
| Corporations and unincorporated organizations | $100,000 per day |
These penalties are among the highest in North America for accessibility non-compliance. The Accessibility Directorate has the power to conduct audits and issue orders.
What “significantly refreshed” means
The AODA applies to new content and content that is significantly refreshed. Organizations sometimes misinterpret this as meaning legacy content is permanently exempt. Courts and the Accessibility Directorate consider a significant refresh to include:
- A major website redesign
- Adding a new section or feature to an existing site
- Substantially rewriting or replacing content
Minor copy edits are not typically considered a significant refresh. However, practically speaking, every content update on a site that has not been made accessible is an opportunity to bring that content into compliance.
Frequently asked questions
Does the AODA apply to intranet sites?
The AODA applies to websites and web content that members of the public access. Internal intranets used only by employees are not subject to the public-facing web standards, but the AODA’s employment standard requires employers to provide accessible formats and communication supports to employees with disabilities upon request — which effectively means intranets should be accessible.
Does the AODA apply to social media?
Social media platforms themselves are not under Ontario’s control. However, the content you post on social media — images, videos, documents — should follow accessibility best practices where possible: alt text on images, captions on videos, accessible links in posts.
We're a national company with offices in Ontario. Does AODA apply to our whole site?
If your organization operates in Ontario and has employees in Ontario, the AODA applies to you. There is no geographic exception for the web content standard — your public-facing website is accessible to Ontarians regardless of where your servers are located.
Our small non-profit has 5 volunteers. Do we need to comply?
The AODA applies to organizations with one or more employee. Volunteers do not count as employees for this purpose. An organization with no paid employees is not covered by the AODA, but may still be subject to the Ontario Human Rights Code if it provides services to the public.
Is there a grace period for old websites?
No. The WCAG Level AA compliance deadlines have passed. The only partial exception is for content that has not been significantly refreshed since before the applicable deadline — but this is a narrow exception and provides no protection if a person files a complaint.
