The Canadian Accessibility Baseline

Canadian accessibility law does not specify a single, unified technical standard. Different laws reference different versions of WCAG, and the standards landscape continues to evolve. This page explains what the recommended Canadian baseline is, why it is WCAG 2.1 Level AA, and what organizations should know about the transition to newer versions.

Why WCAG 2.1 over WCAG 2.0

WCAG 2.1 (published June 2018) added 17 new success criteria across three areas that WCAG 2.0 significantly underserved:

Mobile accessibility (4 criteria)

WCAG 2.0 was written before smartphones became the dominant browsing platform. WCAG 2.1 adds criteria specifically addressing touch interfaces:

CriterionRequirement
1.3.4 OrientationContent is not restricted to a single screen orientation (portrait/landscape)
1.3.5 Identify Input PurposeForm fields that collect personal information identify their purpose (enables autofill)
2.5.1 Pointer GesturesMulti-point or path-based gestures (pinch, swipe) have single-pointer alternatives
2.5.4 Motion ActuationFunctionality triggered by device motion (shaking, tilting) can also be activated by UI

Low vision (7 criteria)

WCAG 2.0’s contrast requirement (4.5:1 for text) was a starting point but left gaps for users with moderate vision loss:

CriterionRequirement
1.4.10 ReflowContent reflows to one column at 320px width (supports 400% zoom)
1.4.11 Non-text ContrastUI components and graphics have 3:1 contrast against adjacent colours
1.4.12 Text SpacingNo loss of content when line height, letter spacing, and word spacing are increased
1.4.13 Content on Hover or FocusHover/focus-triggered content is dismissible, hoverable, and persistent

Cognitive and learning disabilities (6 criteria)

WCAG 2.0 was acknowledged to underserve users with cognitive disabilities. WCAG 2.1 adds:

CriterionRequirement
1.3.5 Identify Input PurposeEnables autofill, reducing cognitive load on forms
2.5.3 Label in NameUI components with visible text labels must include that text in their accessible name
4.1.3 Status MessagesStatus and error messages are programmatically determined (announced by screen readers)

WCAG 2.2: What changed

WCAG 2.2 was published in October 2023. It makes 9 additions and 1 removal relative to WCAG 2.1:

Removed

  • 4.1.1 Parsing — Removed because modern browsers handle malformed HTML gracefully. The criterion no longer adds accessibility value and was difficult to test consistently.

Added (all at Level AA unless noted)

CriterionLevelRequirement
2.4.11 Focus Not Obscured (Minimum)AAKeyboard focus indicator is not fully hidden by sticky headers or overlays
2.4.12 Focus Not Obscured (Enhanced)AAAKeyboard focus indicator is not partially obscured
2.4.13 Focus AppearanceAAAFocus indicator meets minimum size and contrast requirements
2.5.7 Dragging MovementsAADraggable UI (e.g., sliders, sortable lists) has a single-pointer alternative
2.5.8 Target Size (Minimum)AAInteractive targets are at least 24×24 CSS pixels
3.2.6 Consistent HelpAAHelp mechanisms (chat, phone, FAQ) appear in consistent locations
3.3.7 Redundant EntryAAInformation already entered by the user is auto-populated or selectable
3.3.8 Accessible Authentication (Minimum)AACognitive function tests (e.g., CAPTCHAs) are not required unless alternatives exist
3.3.9 Accessible Authentication (Enhanced)AAANo cognitive function tests required for authentication

WCAG 3.0: The horizon

WCAG 3.0 (previously called “Silver”) is under active development by the W3C. It represents a fundamental rethink of how accessibility conformance is measured:

AspectWCAG 2.xWCAG 3.0 (proposed)
Conformance modelBinary pass/fail per criterionScored rating system (Bronze/Silver/Gold)
Testing approachCriterion-by-criterionOutcome-based
CoveragePrimarily web contentWeb, native apps, cognitive load, emotional response
Scope78 criteria (2.1)Hundreds of “outcomes”
StabilityStable, internationally adoptedWorking draft — not stable
Leadership Developer
  • WCAG 2.0 Level AA — satisfies the AODA for Ontario organizations
  • WCAG 2.1 Level AA — satisfies both AODA and ACA framework; addresses mobile, low vision, and cognitive gaps not covered by 2.0

Forward-looking (new projects)

  • WCAG 2.2 Level AA — adds 8 new AA criteria (removes one obsolete one); future-proofs against expected regulatory updates

Enhanced (high-impact public services)

  • WCAG 2.1 Level AA + selected AAA criteria — particularly 1.4.6 Enhanced Contrast, 2.4.9 Link Purpose (Link Only), 3.1.5 Reading Level for content-heavy services

Frequently asked questions

Our legal team says we only need WCAG 2.0. Why are you recommending 2.1?

WCAG 2.1 is backwards-compatible — meeting it means you meet 2.0. There is no downside to targeting 2.1 if your legal minimum is 2.0. The additional 17 criteria in 2.1 address real barriers for real users. The question is not “do we legally have to?” but “do we want our services to work for users with low vision on mobile devices?” The answer should be yes.

How do we document our conformance level for procurement or legal purposes?

Use an Accessibility Conformance Report (ACR) based on the VPAT template (Voluntary Product Accessibility Template). The VPAT 2.4 template has separate sections for WCAG 2.0, 2.1, 2.2, and EN 301 549. Complete the WCAG 2.1 Level AA section at minimum. See Procurement & Compliance for details.

We have legacy content published before WCAG 2.1. Do we need to remediate it?

For the AODA specifically, the obligation applies to new and significantly refreshed content. Legacy content that has not been updated may fall outside the strict letter of the law — but it is still a potential source of human rights complaints if it prevents users with disabilities from accessing your services. A prioritized remediation plan for high-traffic legacy content is strongly recommended.

Should we use EN 301 549 directly instead of WCAG?

EN 301 549 incorporates WCAG by reference — meeting WCAG 2.1 Level AA satisfies the web content requirements of EN 301 549. EN 301 549 also covers non-web software, hardware, and telecommunications products. For digital products beyond websites (native apps, desktop software, kiosks), EN 301 549 provides the broader framework.
