How Ontario businesses and organizations use Sienna to meet the Accessibility for Ontarians with Disabilities Act (AODA) requirements.

Updated on 3/24/2026

AODA Compliance Guide

The Accessibility for Ontarians with Disabilities Act (AODA) is a provincial law in Ontario, Canada, that aims to make the province fully accessible for people with disabilities by 2025.

The Standard

For websites and digital platforms, AODA requires all public sector organizations and large private/non-profit organizations with 50+ employees to meet WCAG 2.0 Level AA.

How Sienna Supports Ontario Business

Large businesses in Ontario utilize Sienna to meet the Information and Communications Standards of the AODA:

  1. Public Information Accessibility: Providing contrast, font resize, and keyboard indicators (WCAG 1.4.3, 1.4.4, 2.4.7).
  2. Equitable Communication: Sienna’s widget ensures that users can interact with your website in a way that suits their abilities.
  3. Visible Commitment: Adding Sienna to your site is an immediate signal of your adherence to the AODA’s mandate for accessibility.

AODA Deadlines

As of January 2021, all public websites must meet WCAG 2.0 Level AA standards. Failure to comply can result in significant fines for corporations and directors.

Strategy for Ontario

  1. Deploy: Add the Sienna script to your website’s header or footer.
  2. Declare: Publish a Canadian-specific Accessibility Statement.
  3. Audit: Use Sienna as the User Interface Layer, then focus your auditing on structural fixes like alt text and semantic tags.
