The Web Content Accessibility Guidelines (WCAG) are not a law. However, some laws, including Section 508 of the Rehabilitation Act of 1973 and the AODA explicitly cite WCAG conformance as an accessibility requirement. Furthermore, the Department of Justice has referenced WCAG standards in its web accessibility enforcement actions. WCAG is considered the global gold standard for web accessibility, so even though WCAG conformance is not a law, following WCAG standards is the most effective way to achieve web accessibility and comply with certain legal mandates.
