It has taken a while but the Guide for the Integrated Accessibility Standard Regulation (IASR) is now available on the AODA.ca website.
The Government’s version spanned some 80 odd pages with many errors and differing list structures, but it is finally ready in 1 single accessible page and can be found in the side menu of the AODA.ca website or go directly there by visiting https://www.aoda.ca/?page_id=1888
