From what I've been able to gather, AODA prescribes compliance with WCAG 2.0 level A and AA, depending on the organization serving the content and the year built. See the table on this page:


According to this chart, for all large organizations (50+ employees) new content built after January 1, 2014 must meet WCAG level A. After 2021, all content will need to meet AA.

The Webaim checklist does a good job of illustrating the differences between A, AA, and AAA.
