The Web Accessibility Standard Ontario Businesses Must Meet
If you own or operate a business in Ontario, there's a good chance your website is already subject to legal accessibility requirements — and many business owners don't realize it until it's too late. Understanding WCAG 2.0 Level AA isn't just about ticking a compliance box. It's about making sure your customers, all of them, can actually use your website.
Here's what you need to know, in plain language.
What the Law Actually Says
The Accessibility for Ontarians with Disabilities Act (AODA), passed in 2005, set out a clear goal: make Ontario fully accessible by 2025. Under Ontario Regulation 191/11, also known as the Integrated Accessibility Standards Regulation (IASR), specific rules apply to websites and web content.
The regulation requires that:
- Private and non-profit organizations with 50 or more employees must conform to WCAG 2.0 Level AA for all public-facing websites and web content
- Government and large public sector organizations faced earlier deadlines and stricter requirements
- New websites and significantly refreshed content had to meet these standards by January 1, 2021
If your business has grown past that 50-employee threshold, this applies to you directly. Smaller organizations are encouraged to comply as well, and the standards represent a widely accepted baseline for inclusive design.
What Is WCAG 2.0 Level AA?
WCAG stands for Web Content Accessibility Guidelines. These are internationally recognized standards developed by the World Wide Web Consortium (W3C) to make web content usable by people with a wide range of disabilities.
The guidelines are organized around four core principles, often called POUR:
- Perceivable — Information must be presented in ways users can detect, such as providing text alternatives for images
- Operable — Users must be able to navigate and interact with your site, including through keyboard-only navigation
- Understandable — Content and interfaces must be clear and consistent
- Robust — Content must work reliably across different assistive technologies like screen readers
WCAG is tiered into three levels: A, AA, and AAA. Level AA is the middle tier and the one Ontario law mandates. It strikes a practical balance — achievable for most businesses without extreme cost, while meaningfully improving access for users with disabilities.
Common Level AA Requirements Include:
- Sufficient colour contrast between text and backgrounds
- Captions on all pre-recorded video content
- Clear and consistent navigation menus
- Forms that are properly labelled so screen readers can interpret them
- No content that flashes more than three times per second (a seizure risk)
- Resizable text without loss of functionality
Why This Matters Beyond Compliance
Roughly 2.6 million Ontarians live with a disability, and many of them rely on accessible websites to shop, book appointments, access services, and engage with businesses just like yours. An inaccessible website doesn't just exclude potential customers — it sends a message that they weren't considered.
Accessible websites also tend to perform better in search engines, load faster, and provide a cleaner user experience for everyone. Accessibility improvements frequently benefit users on mobile devices, older adults, and people in low-bandwidth situations as well.
What Happens If You Ignore It
Ignoring WCAG 2.0 Level AA compliance under the AODA carries real consequences. The Accessibility Directorate of Ontario has the authority to audit organizations and issue compliance orders. Fines for individuals can reach $50,000 per day, and corporations can face penalties of up to $100,000 per day for ongoing non-compliance.
Beyond regulatory risk, businesses have faced reputational damage and human rights complaints when accessibility failures become public. The Ontario Human Rights Code also independently protects people with disabilities from discrimination in services, which can include digital services.
Practical Steps to Move Forward
You don't need to overhaul your entire website overnight. Start with these manageable actions:
- Run an automated accessibility scan on your website to identify the most common issues
- Fix high-priority items first, such as missing image alt text, poor colour contrast, and unlabelled form fields
- Review your video content and add captions where they are missing
- Test your site using keyboard navigation — try using your site without a mouse
- Train your content team on accessible writing and image practices so new content meets standards from the start
- Document your progress — having an accessibility policy and a remediation plan demonstrates good faith to regulators
Working with a web developer who understands WCAG can accelerate the process significantly, particularly for older or more complex websites.
