    AODA Compliance: A Plain-English Guide for Ontario Businesses

    What Ontario's accessibility law asks of your business, sorted by size, with every fact checked against Ontario's own sources.

    Last reviewed . Accessibility rules change, so check the official sources linked below before you rely on a detail.

    AODA compliance reports are due December 31, 2026.

    Applies to Ontario businesses and non-profits with 20 or more employees.

    How to file

    What does AODA compliance mean?

    AODA compliance means meeting the parts of the Accessibility for Ontarians with Disabilities Act and its regulation, O. Reg. 191/11, that apply to your organization. Every Ontario business with at least one employee has duties. At 20 employees you also file a compliance report. At 50, your public website must meet WCAG 2.0 Level AA.

    The AODA has a reputation for being terrifying. Mostly it is a checklist wearing a legal costume. The hard part is working out which items are yours, because the rules change with your employee count.

    This guide does that sorting for you. It sticks to what the Act and the regulation actually say, links to the official source for each point, and flags the places where popular advice gets it wrong (fines, certificates and widgets, mostly). It is general information, not legal advice.

    What applies to your business at its size

    Count every full-time, part-time, seasonal and contract employee in Ontario. Leave out volunteers, independent contractors and staff outside Ontario. Then read across.

    The full list, with the section of the regulation behind each item, is in AODA requirements by business size.

    Where to start if you have done nothing yet

    1. Count your Ontario employees. That number decides almost everything else.
    2. Train your people. Ontario's free AccessForward modules cover the basics at no cost.
    3. Write your policies and add an accessible formats notice. A short line on your website saying people can ask for information in another format meets the notice part.
    4. If you have 20 or more employees, file the report before December 31, 2026. The portal is free.
    5. If you have 50 or more, check your website against WCAG 2.0 Level AA. That is the part most businesses need outside help with.

    What about your website?

    The WCAG 2.0 Level AA rule applies to businesses and non-profits with 50 or more employees, and to the designated public sector. It covers public websites and web content published after January 1, 2012, whether you run the site yourself or pay someone to. Our AODA website requirements page covers it in detail.

    Under 50, the specific website rule does not apply. You still have to provide information in an accessible format when someone asks, and a site that a screen reader cannot get through still loses you the sale. The accessibility checklist is a good free first pass.

    Four things the AODA does not require

    • An accessibility widget or overlay. The rule is about the site meeting WCAG, not about a menu. In April 2025 the U.S. Federal Trade Commission ordered accessiBe to pay $1 million and barred it from claiming its automated products make any website WCAG-compliant without evidence.
    • An "AODA certified" badge. We have not found any Ontario program that certifies websites. The official process is a compliance report your own senior officer certifies.
    • WCAG 2.2. The regulation names WCAG 2.0 Level AA. Version 2.2 is a good target for a new build, not a legal requirement.
    • An automatic $100,000-a-day fine. Most penalties are far smaller. The fines guide has the actual schedule.

    Questions Ontario business owners ask about AODA compliance

    What does AODA compliant mean?

    It means your organization meets the requirements of the Accessibility for Ontarians with Disabilities Act and its Integrated Accessibility Standards Regulation (O. Reg. 191/11) that apply to your size and sector. That covers things like accessible customer service, staff training, policies, accessible formats on request and, for organizations with 50 or more employees, websites that meet WCAG 2.0 Level AA.

    Is AODA mandatory for my business?

    Yes, if you have at least one employee in Ontario. Ontario says businesses and non-profits are exempt only if they have no employees in Ontario. What you must do depends on your size: 1 to 19, 20 to 49, or 50 or more employees.

    Who enforces the AODA?

    Ontario's Ministry for Seniors and Accessibility. The ministry collects compliance reports, audits and inspects organizations, and can issue orders and administrative penalties through directors appointed under the Act. Orders can be reviewed and appealed to the tribunal designated under the Act.

    Is there an official AODA certification for a website?

    We have not found any Ontario program that certifies a website as AODA compliant. The official process is the accessibility compliance report, which a senior officer of your own organization certifies. Treat any "AODA certified website" badge as marketing, not a government approval.

    Can an accessibility widget make my website AODA compliant?

    No. The AODA website rule is about meeting WCAG 2.0 Level AA, not adding a menu. In April 2025 the U.S. Federal Trade Commission finalized an order requiring accessiBe to pay $1 million and barring it from claiming its automated products can make any website WCAG-compliant without evidence.

    Does AODA require WCAG 2.2?

    No. O. Reg. 191/11 names WCAG 2.0 Level AA, with live captions and pre-recorded audio description excepted. WCAG 2.2 is the current W3C version, so it is a sensible target for a new build, but it is not what the regulation requires.
