ACA on Next.js: complete compliance checklist
Implementing ACA compliance on Next.js means addressing the platform's specific failure modes (spa route changes not announced, modal focus management) while applying Accessible Canada Act success criteria across content, code, and editorial workflow.
ACA in 60 seconds
The Accessible Canada Act (ACA, 2019) requires federally regulated entities — federal government, banks, telecom, broadcasting, transportation — to identify, remove and prevent accessibility barriers, with the explicit goal of "a Canada without barriers by 2040" and detailed regulations layered on top including the ICT regulations referencing EN 301 549.
Next.js accessibility — what you are starting with
Next.js delivers SSR/RSC HTML that is screen-reader friendly out of the box, but client-side interactions (modals, route changes, dynamic content) require explicit accessibility work.
ACA setup checklist for Next.js
1. Use semantic HTML in components: Prefer button over div + onClick; use header/main/nav.
2. Announce route changes: Use a live region or react-aria utilities to announce.
3. Test with axe-core and AT: Wire @axe-core/react in dev; manual NVDA/VoiceOver pass per page.
Common ACA failures on Next.js
• SPA route changes not announced
• Modal focus management
• Dynamic content not announced
• Image component alt prop omission
Putting it together
Combine ACA's Level AA requirements with Next.js's native tooling. Bake accessibility into your component library and editorial workflow; instrument axe-core in CI for regression.

Is Next.js ACA-compliant out of the box?
Next.js produces HTML; accessibility is the developer's responsibility. SSR/RSC give Next.js an advantage over pure SPA because initial markup is parseable.
What is the easiest path to ACA compliance on Next.js?
Start with the platform's most-accessible default theme (where applicable), audit each installed plugin/extension/module, train content authors on alt text and heading hierarchy, and instrument axe-core in your CI pipeline.
Is Next.js accessible by default?
Next.js produces HTML; accessibility is the developer's responsibility. SSR/RSC give Next.js an advantage over pure SPA because initial markup is parseable.
