Today• What is accessibility?• What is AODA?• The many faces of AODA:
• Web• PDF• Video
• What can you do to prepare yourself?
Disclaimer• Today’s presentation represents our admittedly
imperfect understanding of accessibility and AODA.• We advise you not to rely on this imperfect
understanding, but to use it as a starting point for educating yourself and finding out more fully about AODA, its requirements and implications.
• Remember: AODA is a legal requirement. It’s an act of law in Ontario. Educate yourself.
• We’re neither AODA nor accessibility experts: we’re two guys who did the best we could to try to figure things out and educate ourselves.

The art & the science
IMAGINE THIS
Most information is visual
Visual ≠ effective• Not everyone can process information
visually• Common methods ≠ effective
methods
One in seven• About 1.85 million people in Ontario
have a disability • Estimate that approximately half a
million Canadians live with significant vision loss• We need to reconsider how to communicate
Accessibility for Ontarians with Disabilities Act•Introduced in 2005•Sets out a process for developing and enforcing accessibility standards
•Accessibility standards are laws that government, businesses, non-profits and public sector organizations must follow
Information and communications standard•Aims to remove barriers to information for people with disabilities
•Is based on World Wide Web Consortium Web Content Accessibility Guidelines
•Three levels A, AA, AAA• Beginning Jan 1, 2014: new public websites, significantly refreshed
websites and any web content posted after January 1, 2012 must meet Web Content Accessibility Guidelines (WCAG) 2.0 Level A
• Beginning January 1, 2021: all public websites and web content posted after January 1, 2012 must meet WCAG 2.0 Level AA other than criteria 1.2.4 (live captions) and 1.2.5 (pre-recorded audio descriptions)

Video• Speaking about YouTube specifically
Some of the concerns for video
• Captioning• Text contrast• Described audio• Strobing
Described video• We’ve been advised
by one expert that isn’t required for AODA, but is still a best practice
• (That’s one expert’s opinion)
