Many Ontario business owners assume accessibility law is mostly about ramps and doorways — until they learn that the Accessibility for Ontarians with Disabilities Act, 2005 also has something to say about websites. Website accessibility requirements in Ontario can genuinely apply to your business's digital presence, but which obligations apply, and when, depends on details many owners have never checked.

This article explains what AODA's information and communications rules actually cover online, how to tell whether your website is in scope, and practical steps toward compliance.

AODA in Brief: What the Law Requires

AODA sets accessibility standards across several areas of business and public life, developed under regulations made pursuant to the Act. One of those areas — the Information and Communications Standard — addresses how organizations make information accessible, and it extends to digital content including websites. The specific obligations, and the timelines and organization-size thresholds that trigger them, are set out in the regulations and have been updated over time, so it is worth confirming the current requirements that apply to your organization's size and sector rather than assuming an older rule of thumb still holds.

Does the Standard Apply to Your Website?

Whether your specific website has a legal compliance obligation typically turns on factors such as:

Because these thresholds and dates are the kind of detail that changes with regulatory updates, confirm the current rule for your organization's size before concluding you are, or are not, covered.

What "Accessible" Actually Means in Practice

Where the standard applies, it generally points businesses toward a recognized technical benchmark for accessible web content — commonly referenced as the Web Content Accessibility Guidelines (WCAG). In practical terms, an accessible website typically means things like:

You do not need to become a web-accessibility engineer to grasp the goal: someone using a screen reader, a keyboard-only setup, or a visual impairment should be able to actually use your site, not just technically load it.

Common Accessibility Gaps on Small-Business Websites

Most of these gaps are fixable without rebuilding a site from scratch — but only once someone actually audits for them, since they rarely show up in an ordinary visual review.

A Practical Path to Compliance

  1. Confirm whether your organization is currently covered, and by which specific obligations, given your size and sector.
  2. Audit your existing website against a recognized accessibility standard, ideally with a tool or reviewer who checks it functionally, not just visually.
  3. Prioritize fixes — some gaps (missing alt text, low contrast, unlabelled forms) are quick wins; others (a full navigation redesign) take longer.
  4. Build accessibility into your process going forward, so new pages and content are accessible by default rather than something you retrofit later.
  5. Document what you've done. A paper trail showing genuine, ongoing effort matters if your practices are ever questioned.

What Happens If a Business Doesn't Comply

AODA is enforced through a compliance and complaints framework, and non-compliance can lead to consequences under the Act and its regulations. The specific enforcement mechanisms and any penalty amounts are set out in the legislation and its regulations directly — this is a detail worth confirming with current, primary sources or legal advice rather than relying on a figure you may have seen quoted elsewhere, since these details are exactly the kind that get out of date.

Frequently asked questions

Does my small business definitely need an accessible website?

It depends on your organization's size, sector, and the specific thresholds in force, which can change with regulatory updates. Rather than guessing, confirm your organization's current obligations — and even where a legal obligation is unclear, a more accessible website is generally good business practice regardless.

Is a website accessibility "checker" tool enough to confirm compliance?

Automated tools catch a meaningful share of common issues, like missing alt text or poor contrast, but they cannot fully verify a real user's experience with assistive technology. Treat an automated scan as a useful first pass, not a final verdict.

Do accessibility requirements apply to my social media pages too, or just my own website?

AODA's information and communications obligations are generally framed around information and communications a business controls and publishes, which can extend beyond just your own website depending on the specific rule and context. This is worth confirming for your specific situation rather than assuming either way.

If I redesign my website anyway, should I build in accessibility from the start?

Yes. It is generally far less costly to design for accessibility from the outset than to retrofit an existing site later, and doing so also reduces the risk of falling out of step with evolving requirements.
