What Is Ontario Regulation 191/11?
If you run a business in Ontario and have a website, there's a good chance you've heard the term "AODA" thrown around. But the specific rule that governs your website's accessibility is Ontario Regulation 191/11, formally known as the Integrated Accessibility Standards Regulation (IASR). It was enacted under the Accessibility for Ontarians with Disabilities Act, 2005 (AODA) and sets out clear, legally binding requirements for how businesses must make their digital content accessible to people with disabilities.
The good news? Understanding what's required doesn't take a law degree. Here's what you need to know.

Who Does This Regulation Apply To?
Ontario Regulation 191/11 applies to both public and private sector organizations in Ontario. For small and medium businesses, the requirements are tiered based on your organization's size:
- 1–49 employees — you're classified as a small private sector organization
- 50+ employees — you fall under large private sector organization rules with stricter deadlines and documentation requirements
Even if you have only a handful of staff, if you have a public-facing website, this regulation affects you. The internet doesn't have a "small business exemption."

What Does the Regulation Actually Require?
The web accessibility portions of Ontario Regulation 191/11 fall under the Information and Communications Standards. The core requirement is that your website and web content must conform to the Web Content Accessibility Guidelines (WCAG) 2.0, Level AA.
What WCAG 2.0 AA Means in Plain Language
WCAG 2.0 AA is an internationally recognized set of technical standards. For your website, this generally means:
- Images have descriptive alt text so screen readers can describe them to visually impaired users
- Videos include captions for users who are deaf or hard of hearing
- Text has sufficient colour contrast so it's readable by people with low vision
- The site is keyboard-navigable for users who cannot use a mouse
- Forms and buttons are clearly labelled so assistive technologies can interpret them
Key Deadlines
The regulation's compliance deadlines have already passed for most organizations:
- January 1, 2014 — New websites and significantly refreshed content for large organizations
- January 1, 2021 — All public websites and web content for both small and large private organizations
This means if your business website is currently live and hasn't been reviewed for accessibility, you are likely out of compliance right now.

Why This Matters Beyond Legal Obligation
Accessibility isn't just about avoiding fines — though those are real. Consider that approximately 2.6 million people in Ontario live with a disability. That's a significant portion of your potential customer base. An inaccessible website is effectively a locked door for those customers.
There are also strong business reasons to comply:
- Broader audience reach — accessible sites serve everyone better, including aging populations
- Improved SEO — many accessibility best practices align with what search engines reward
- Reduced legal risk — complaints can be filed with the Accessibility Directorate of Ontario, and penalties for organizations that fail to comply can reach $100,000 per day for corporations
- Brand reputation — customers increasingly choose businesses that demonstrate inclusivity

Practical Steps to Get Started
You don't need to overhaul your entire website overnight. A measured, prioritized approach works well for most small businesses.
Step 1: Audit Your Current Website
Use an automated accessibility scanning tool to identify your most critical issues. This gives you a clear picture of where you stand before spending a dollar.
Step 2: Prioritize the High-Impact Fixes
Focus first on issues that block access entirely — missing form labels, absent alt text on important images, and poor colour contrast on body text are common starting points.
Step 3: Work With an Accessible-Aware Developer
When updating or rebuilding pages, choose a developer or agency familiar with WCAG 2.0 AA standards. Ask specifically about accessibility before signing any contract.
Step 4: Document Your Efforts
Large organizations must file Accessibility Compliance Reports with the province. Even as a small business, keeping internal records of your efforts demonstrates good faith if a complaint is ever filed.
Step 5: Establish an Ongoing Process
Accessibility isn't a one-time project. Every time you add new content, pages, or features, check them against WCAG 2.0 AA standards. Build it into your normal workflow.

The Real Cost of Ignoring It
Businesses that ignore Ontario Regulation 191/11 face more than government penalties. A single formal complaint to the Accessibility Directorate can trigger an audit of your entire organization. Beyond that, reputational damage and lost customers are costs that don't show up in a fine notice but hit your bottom line just as hard.
The regulation exists because inclusion is a right in Ontario — not a feature businesses opt into when convenient.
