The Accessibility for Ontarians with Disabilities Act (AODA) concerns the public sector and large organizations with over 50 employees.

The Ontario Government’s goal for the province is to become completely accessible by 2025.

What is an AODA Compliant Website?

Accessibility for Ontarians with Disabilities Act (AODA) guides web developers and technical coders to create a website that complies with this law. (link to the law).

If this is not possible, make sure you use software that supports accessibility the next time you refresh your site.

For example, it may be impossible to make some online maps and complex diagrams accessible to people with visual disabilities, you may still post the content, but you must provide it in an accessible format upon request.
