Web accessibility has moved from "nice to have" to legally required for a significant and growing number of Canadian businesses. If your website can't be used by people with disabilities — visual, auditory, motor, or cognitive — you're potentially excluding 22% of the Canadian population, violating federal or provincial law, and exposing your organization to human rights complaints.
Here's a comprehensive guide to accessibility requirements in Canada and what they mean for your website.
The Legal Landscape in Canada
The Accessible Canada Act (ACA)
The Accessible Canada Act, in force since 2019, requires federally regulated organizations — banks, telecom companies, federal Crown corporations, federal government contractors — to identify and eliminate accessibility barriers by 2040, with proactive reporting requirements.
If you're a business that contracts with the federal government or that falls under federal regulation (broadcasting, telecommunications, interprovincial transportation), accessibility compliance is a legal obligation, not a choice.
AODA — Ontario's Accessibility for Ontarians with Disabilities Act
Ontario's AODA is the most comprehensive provincial accessibility legislation in Canada. Its Integrated Accessibility Standards require private-sector businesses with 50+ employees to meet WCAG 2.0 Level AA by specified deadlines. Smaller businesses (1–49 employees) have lighter requirements but are not exempt.
AODA applies to Ontario-based organizations and those doing business in Ontario. For any business with Ontario customers or operations, AODA is a relevant compliance framework.
Other Provincial Legislation
British Columbia, Nova Scotia, Manitoba, and other provinces have accessibility legislation in various stages of development and enforcement. The trend is toward stricter requirements, not less.
Human Rights Exposure
Even for businesses not directly covered by specific accessibility legislation, inaccessible websites can give rise to complaints under human rights codes. The Canadian Human Rights Commission and provincial equivalents have adjudicated cases involving inaccessible digital services. The exposure exists regardless of legislation.
What WCAG 2.1 AA Requires
The Web Content Accessibility Guidelines (WCAG) are the international technical standard for web accessibility. WCAG 2.1 Level AA is the standard referenced in most Canadian legislation. Here's what it requires in plain language:
Perceivable
All visual content must have text alternatives. Images require descriptive alt text. Videos need captions and audio descriptions. Content can't rely on colour alone to convey information (e.g., "required fields are shown in red" is insufficient without another indicator).
Colour contrast must meet minimum ratios: 4.5:1 for normal text, 3:1 for large text. Many websites fail this requirement simply because designers chose visually appealing light grey text on white backgrounds.
Operable
Every function on your website must be accessible via keyboard (without requiring a mouse). This means tab navigation, keyboard-accessible menus, and no "keyboard traps" that leave users stuck.
Sufficient time must be given for time-limited content (session timeouts, rotating carousels). Motion and flashing content must be controllable to prevent triggering seizures.
Understandable
The page language must be declared in HTML so screen readers pronounce content correctly. Forms must provide clear labels and helpful error messages. Navigation must be consistent across pages.
Robust
The website must work with current assistive technologies — screen readers (NVDA, JAWS, VoiceOver), screen magnifiers, alternative input devices. This means clean semantic HTML, proper ARIA landmark roles, and testing with actual assistive technology.
Common Accessibility Failures on Canadian Business Websites
These are the most frequent issues we identify in accessibility audits:
1. Missing or inadequate alt text Images without alt text are invisible to screen reader users. Even worse: decorative images with meaningless alt text ("image1.jpg") that screen readers announce as content.
2. Inaccessible forms Form inputs without associated labels. Error messages that appear visually but aren't announced to screen readers. Required fields indicated only by colour.
3. Keyboard accessibility
Dropdown menus that only work on hover. Custom interactive components (date pickers, modals, carousels) that don't respond to keyboard events. Focus indicators removed with outline: none in CSS.
4. Colour contrast failures Light grey text, reversed-out white text on dark images, ghost buttons with insufficient contrast — these are extremely common in contemporary design trends and frequently fail contrast requirements.
5. Missing ARIA labels Icon-only buttons (hamburger menus, search icons, social media icons) without accessible names. Screen reader users hear "button, button, button" without knowing what each button does.
6. PDFs Untagged PDFs — the majority of PDFs on Canadian business websites — are largely inaccessible to screen readers. Tagged PDFs with proper heading structure, reading order, and alt text are required for accessibility compliance.
7. Video without captions Videos without closed captions exclude deaf and hard-of-hearing users. Auto-generated captions from YouTube are a starting point but typically require manual correction for accuracy.
The Business Case Beyond Compliance
Accessibility is a business issue as well as a compliance issue:
Market size: 6.2 million Canadians have a disability. This represents $55 billion in annual spending power. An inaccessible website excludes this market.
SEO: Accessibility best practices overlap significantly with search engine optimization. Alt text, semantic HTML, descriptive link text, and page structure all improve both accessibility and search rankings.
Mobile usability: Many accessibility improvements also improve mobile usability for all users — larger touch targets, clear navigation, content that works without JavaScript.
Legal risk: A single human rights complaint can result in remediation requirements, reputational damage, and legal costs that far exceed the investment in building accessibly from the start.
Getting Your Website Audited and Remediated
Automated testing: Tools like axe, WAVE, and Lighthouse catch a portion of accessibility issues automatically (roughly 30–40% of WCAG failures). Run these tools as a starting point and fix every issue they identify.
Manual testing: Automated tools miss many critical issues, including keyboard navigation, focus management, screen reader experience, and logical content order. Manual testing by someone trained in accessibility evaluation is required for meaningful compliance assessment.
User testing: The most valuable accessibility testing involves real users with disabilities. Organizations building accessible products should include disabled users in their testing process.
Remediation: Once issues are identified, remediation ranges from quick fixes (adding alt text, improving colour contrast) to structural changes (rebuilding inaccessible interactive components). Prioritize by severity and user impact.
What Cleva IT Does for Accessible Web Development
All websites we build at Cleva IT are developed to WCAG 2.1 AA as a baseline standard, not an optional add-on. This means:
- Semantic HTML structure with proper heading hierarchy
- All images with meaningful alt text
- Keyboard-navigable interactions
- Colour contrast that meets WCAG requirements (tested, not assumed)
- ARIA labels on all icon-only interactive elements
- Forms with associated labels and accessible error handling
- Focus indicators that are visible and clear
For existing websites, we offer accessibility audits that identify all WCAG 2.1 AA violations, prioritize them by impact, and provide a remediation plan with cost estimates. We can implement the remediation ourselves or work alongside your existing development team.
The cost of building accessibly from the start is modest. The cost of retrofitting an inaccessible website — or responding to a human rights complaint — is substantially higher. Canadian businesses that build accessible websites are making a smart business decision as well as the right ethical choice.
