Accessibility for Ontarians with Disabilities Act (AODA)
Website Compliance Guide

The Accessibility for Ontarians with Disabilities Act (AODA) is legislation enforced in the Canadian province of Ontario to identify, remove, and prevent barriers for people with disabilities. Enacted in 2005, the Act aimed to achieve a barrier-free Ontario by January 1, 2025—making the province fully accessible in regards to goods, services, facilities, accommodations, employment, buildings, structures, and premises.

The Act applies to Ontario government bodies, private businesses, non-profits, and public sector organizations operating within the province.

Accessibility for Ontarians with Disabilities Act Overview

The AODA refers to the definition of disability from the Ontario Human Rights Code, which includes:

• Blindness or visual impairments
• Deafness or hearing impairments
• Muteness or speech impediments
• Physical impairments (paralysis, mobility issues, etc.)
• Neurological disabilities (epilepsy, brain injury, etc.)
• Mental impairments or developmental disabilities
• Intellectual or learning impairments
• Mental disorders

The Five AODA Standards

The AODA establishes a legislative framework to develop, implement, and enforce five standards for accessibility compliance:

1. Customer Service Standard — Requirements for providing accessible customer service
2. Information and Communications Standard — Rules for accessible information, including web content
3. Employment Standard — Accessible recruitment, hiring, and return-to-work practices
4. Transportation Standard — Accessible public transportation services
5. Design of Public Spaces Standard — Accessible outdoor spaces and buildings

Web accessibility falls under the Information and Communications Standard, which covers how information is made accessible to people with disabilities—including all public-facing websites and digital content.

AODA Web Accessibility Requirements

Under the Information and Communications Standard, Ontario organizations must make their websites and digital content accessible according to specific technical standards.

Who Must Comply?

All Ontario public sector organizations and large private sector organizations (50 or more employees) that:

• Provide goods, services, or facilities
• Employ people in Ontario
• Offer accommodation
• Own or occupy buildings or premises
• Participate in local business activity

These organizations were required to make their websites WCAG 2.0 Level AA compliant by January 1, 2021.

Small Business Obligations

Businesses with fewer than 50 employees have reduced obligations but are not fully exempt. They must still:

• Provide accessible formats and communication supports upon request
• Train staff on accessibility requirements
• Follow customer service accessibility standards

Organizations with 20-49 employees must file accessibility compliance reports but have more limited web accessibility requirements than larger organizations.

AODA and WCAG: Technical Standards

Under the Information and Communications Standard, all web content must comply with the Web Content Accessibility Guidelines (WCAG) 2.0 Level AA, and subsequent versions. WCAG 2.2 is now the current published version, and while the AODA has not yet been formally updated to require it, organizations are encouraged to target WCAG 2.1 or 2.2 as best practice.

The Four Principles of WCAG (POUR)

Perceivable

• Provide text alternatives for non-text content (images, videos, podcasts)
• Provide alternatives for time-based media (captions, transcripts)
• Ensure content can be displayed in different ways without losing context
• Maintain good color contrast between text and backgrounds
• Provide audio controls (pause, volume)

Operable

• Ensure all functionality is accessible via keyboard-only navigation
• Give users enough time to read content or control timing
• Avoid content that flashes more than three times per second
• Provide clear, intuitive navigation with well-defined headings and links

Understandable

• Ensure text is readable by users and compatible with screen readers and other assistive technologies
• Make pages operate predictably with consistent navigation and styling
• Help users avoid and correct mistakes with clear labels and error messages

Robust

• Ensure compatibility with current assistive technologies
• Build websites that adapt to future user agents and tools

AODA Compliance Requirements

Beyond technical web standards, organizations must fulfill administrative obligations:

Required Documentation

• Accessibility policy — Document your organization's commitment to accessibility
• Multi-year accessibility plan — Create and update every five years
• Staff training — Train employees and volunteers on accessibility requirements

Accessibility Compliance Reports

Organizations must file accessibility reports confirming ongoing compliance:

• Public sector organizations: Every two years (next deadline: December 31, 2025)
• Private businesses and non-profits: Every three years (next deadline: December 31, 2026)

AODA Compliance Timeline

Key dates for web accessibility under AODA:

• January 1, 2014: New websites and web content must conform to WCAG 2.0 Level A
• January 1, 2021: All websites must conform to WCAG 2.0 Level AA (except criteria 1.2.4 live captions and 1.2.5 pre-recorded audio descriptions)
• June 30, 2021: Extended deadline for accessibility reports (businesses with 20+ employees)
• January 1, 2025: Target date for barrier-free Ontario

AODA Enforcement and Penalties

Failure to comply with AODA accessibility laws results in significant monetary penalties:

• Individuals: CA$50,000 per day the offense continues
• Corporations: CA$100,000 per day the offense continues
• Directors/Officers: CA$50,000 per day for personal liability

The Ontario government conducts audits and can issue compliance orders, director's orders, and administrative penalties for non-compliant organizations.

ADA vs. AODA: What's the Difference?

Organizations operating in both the US and Canada often ask how these accessibility laws compare.

Americans with Disabilities Act (ADA)

• Jurisdiction: United States (federal law)
• Scope: Civil rights law covering employment, public services, public accommodations
• Web standard: No formal technical standard codified; WCAG used as litigation benchmark
• Enforcement: Primarily private lawsuits; DOJ enforcement for Title II

Accessibility for Ontarians with Disabilities Act (AODA)

• Jurisdiction: Ontario, Canada (provincial law)
• Scope: Five specific accessibility standards including web content
• Web standard: WCAG 2.0 Level AA explicitly required
• Enforcement: Government audits, compliance orders, administrative penalties

Can a Website Be 100% Compliant?

Complete accessibility compliance is an ongoing process rather than a final destination. While organizations can achieve conformance with specific WCAG success criteria, accessibility requires continuous monitoring as content changes, technologies evolve, and user needs vary. The goal is continuous improvement toward barrier-free digital experiences.

How to Assess and Maintain AODA Compliance

Automated Testing

Use accessibility scanning tools like Acquia Web Governance to identify machine-testable issues against WCAG 2.0, 2.1, and 2.2 criteria. Automated tools efficiently detect issues like missing alt text, color contrast failures, and improper heading structure.

Manual Testing

Automated tools catch only 30-40% of accessibility issues. Manual testing is essential:

• Keyboard-only navigation — Test all functionality without a mouse
• Screen reader testing — Verify content works with NVDA, JAWS, or VoiceOver
• Visual inspection — Check focus indicators, reading order, and form labels

Ongoing Monitoring

Accessibility is not a one-time project. Establish processes for:

• Regular automated scans
• Periodic manual audits
• Training for content creators
• User feedback mechanisms

How Acquia Can Help

Acquia Web Governance's Web Accessibility Module audits your entire site against WCAG 2.0, 2.1, and 2.2 (and subsequent updates).

Each audit scans for machine-testable issues, provides detailed reports, gives targeted recommendations, and shows compliance status across Levels A, AA, and AAA. Track your accessibility compliance progress via reports in the History Center.

We also offer accessibility training to ensure your team is well-versed in both automated and manual remediation methods.

Acquia provides free tools including a Color Contrast Checker for testing compliant color combinations and an Accessibility Statement Generator for creating public accessibility commitments.
