Web Accessibility: Why It Matters and What WCAG 2.1 AA Really Means
1 in 5 Canadians has a disability. If your website isn't accessible, you're excluding millions of potential users. Here's what accessibility means in practice.
Over 6.2 million Canadians — roughly 22% of the population — report having a disability. When websites aren't accessible, these millions of people are excluded from essential information and services. For a disability services directory like ours, accessibility isn't optional — it's fundamental to our mission.
What Is Web Accessibility?
Web accessibility means designing and developing websites so that people with disabilities can perceive, understand, navigate, and interact with them. This includes people who are:
- Blind or low vision — using screen readers, magnification, or high contrast
- Deaf or hard of hearing — needing captions, transcripts
- Motor impaired — using keyboard only, voice control, or switch devices
- Cognitively diverse — needing clear language, consistent navigation, reduced distractions
WCAG 2.1 AA: The Standard
The Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA is the standard most organizations target. It covers four principles:
Perceivable: - Text alternatives for images - Captions for video - Content can be presented in different ways - Color is not the only way information is conveyed - Minimum contrast ratio of 4.5:1 for text
Operable: - All functionality available from keyboard - Users have enough time to read content - Content doesn't cause seizures - Users can navigate and find content easily
Understandable: - Text is readable and understandable - Content appears and operates in predictable ways - Users are helped to avoid and correct mistakes
Robust: - Content is compatible with assistive technologies - Valid, semantic HTML
Quick Wins for Any Website
- Use semantic HTML — headings (h1-h6), lists, nav, main, footer
- Add alt text to all meaningful images
- Ensure keyboard navigation — tab through your entire site
- Check color contrast — use tools like the WebAIM contrast checker
- Label form inputs — every input needs an associated label
- Make touch targets 44x44px minimum on mobile
- Test with a screen reader — even briefly
The Business Case
Beyond being the right thing to do, accessibility improves SEO (semantic HTML), helps mobile users, and in many jurisdictions is legally required. The Accessible Canada Act (ACA) establishes accessibility standards that federally regulated organizations must meet.
Our Commitment
At Able Canada, we build with WCAG 2.1 AA as our baseline. We use semantic HTML, ARIA labels, skip navigation, keyboard-navigable components, and test with screen readers. Our accessibility panel lets users adjust font size, contrast, and animations to their needs.
