AODA Website Accessibility Requirements for Ontario Businesses & Municipalities

If your organization operates in Ontario, your website is required to meet accessibility standards under the Accessibility for Ontarians with Disabilities Act (AODA). This applies to businesses with 50 or more employees, all public sector organizations, and every municipality in the province.

Despite the law being in effect since 2014, a significant number of Ontario websites still fail to meet the minimum requirements. Many organizations are unaware of the specific technical standards — or what it actually takes to comply. Need help getting compliant? Learn about our AODA accessibility audit and remediation services.

What Does the AODA Require for Websites?

Under the AODA's Integrated Accessibility Standards Regulation (IASR), all public-facing websites and web content must conform to WCAG 2.0 Level AA. This is the international standard for web accessibility set by the World Wide Web Consortium (W3C).

In plain terms, WCAG 2.0 Level AA means your website must be:

• Perceivable — all content can be seen, heard, or read by assistive technology. Images need alt text, videos need captions, and text must have sufficient colour contrast.
• Operable — every function works with a keyboard alone. Menus, forms, and links must be navigable without a mouse.
• Understandable — content is clearly written, forms provide helpful error messages, and navigation is consistent across pages.
• Robust — the site works reliably across browsers, devices, and assistive technologies like screen readers.

Who Needs to Comply?

• All Ontario municipalities — towns, cities, counties, and regional governments
• Broader public sector — hospitals, school boards, colleges, universities, public transit
• Large private sector — businesses with 50+ employees
• Small businesses (1–49 employees) — required to make new websites accessible, recommended to fully comply

Most Common Accessibility Violations

Based on our audits of Ontario municipal and business websites, these are the issues we see most frequently:

1. Missing alt text on images — screen readers cannot describe the image to visually impaired users
2. Low colour contrast — text that doesn't meet the 4.5:1 contrast ratio against its background
3. Missing form labels — input fields without proper labels are unusable with assistive technology
4. No keyboard navigation — dropdown menus and interactive elements that only work with a mouse
5. Inaccessible PDFs — scanned documents published as images inside PDFs, with no text layer
6. Missing page titles and heading structure — pages without proper H1/H2/H3 hierarchy
7. Auto-playing media — videos or audio that play automatically without user control

What Are the Consequences of Non-Compliance?

The AODA includes enforcement provisions. Organizations that fail to comply can face:

• Administrative penalties — up to $50,000 per day for individuals, $100,000 per day for corporations
• Compliance orders — mandatory remediation with deadlines
• Public reporting — non-compliant organizations may be named publicly
• Human rights complaints — individuals can file complaints under the Ontario Human Rights Code

Beyond legal risk, an inaccessible website creates real barriers for community members with disabilities — residents who need to access public services, pay bills, read meeting agendas, or submit permit applications.

How to Check If Your Website Is Compliant

A proper accessibility audit combines automated scanning with manual review. Automated tools can catch technical violations like missing alt text and contrast issues, but manual testing is needed to evaluate keyboard navigation, screen reader compatibility, and content structure.

Key steps in an accessibility audit:

1. Automated scan — crawl every page for WCAG 2.0 Level AA violations
2. Manual review — test keyboard navigation, form usability, and screen reader output
3. Document review — check that PDFs and downloadable files are accessible
4. Prioritized report — categorize issues by severity and provide actionable fixes

How to Fix Accessibility Issues

Most accessibility issues are straightforward to fix once identified. Common remediation steps include:

• Adding descriptive alt text to all meaningful images
• Adjusting colour contrast ratios in your CSS
• Adding proper labels to all form fields
• Ensuring all interactive elements are keyboard-accessible
• Rebuilding PDFs with proper text layers and heading structure
• Adding skip-navigation links for keyboard users
• Implementing proper ARIA attributes where needed

The key is knowing exactly what needs to be fixed. Without a thorough audit, most organizations are guessing. If you are building or redesigning a website, our guide on why every Ontario business needs a professional website explains how to build accessibility in from the start. Our AODA compliance service covers the full process — from initial scan to remediation and ongoing monitoring.

Key Takeaways

• AODA requires WCAG 2.0 Level AA compliance for Ontario organizations
• Municipalities and public sector organizations have the strictest requirements
• Most websites have fixable issues — missing alt text, low contrast, and keyboard navigation are the most common
• An accessibility audit is the first step toward compliance
• Non-compliance carries financial penalties and excludes community members with disabilities
