AODA Website Compliance for Ontario Businesses: What's Actually Required

AODA (the Accessibility for Ontarians with Disabilities Act, 2005) is a framework. The duties that touch a business website sit in one regulation, the Integrated Accessibility Standards Regulation (IASR, O. Reg. 191/11), consolidated on 30 March 2026. As of 15 October 2026, the practical order is:

1. Customer service standard. Applies to every "obligated organization" that provides goods, services or facilities (Part IV.2, section 80.45). That includes a small organization: one with at least one but fewer than 50 employees in Ontario.
2. Information and communications standard. Every obligated organization has to make its feedback process accessible (section 11) and provide accessible formats and communication supports on request, at no more than the regular cost (section 12). The website rule in section 14 sits here too, and it is scoped by size.
3. Training. Employees, volunteers and anyone who provides goods or services on your behalf are trained on the standards and on the Human Rights Code as it applies to persons with disabilities (section 7).
4. Reporting. Businesses and non-profits with 20 or more employees file an accessibility compliance report every three years.

The regulation defines a "large organization" as one with 50 or more employees in Ontario. Section 14 then sets the website schedule.

Three details in section 14 matter when you plan a site. It covers web content published on a website after 1 January 2012, so older content is outside it. It covers sites and web-based applications you control "directly or through a contractual relationship that allows for modification of the product", so a vendor-built site is still yours. And it applies "except where meeting the requirement is not practicable"; the regulation lets an organization consider, among other things, the availability of commercial software or tools. The Province's website guidance, updated 21 September 2026, says the same about who must comply and which content is covered.

WCAG 2.0 is the W3C standard the regulation names. It is organised around four principles: content must be perceivable, operable, understandable and robust. For a small business site, the success criteria that come up most are:

• Text alternatives (1.1.1). Every image that conveys information has a text alternative that does the same job.
• Captions (1.2.2). Pre-recorded video with sound has captions. Live captions (1.2.4) and pre-recorded audio description (1.2.5) are the two Level AA criteria Ontario exempts.
• Keyboard (2.1.1, 2.1.2). Everything works by keyboard alone, and focus never gets stuck in a component.
• Colour (1.4.1, 1.4.3). Colour is never the only way information is shown, and text meets a contrast ratio of at least 4.5:1 (3:1 for large text).
• Forms (3.3.1, 3.3.2). Inputs have labels or instructions, and errors are described in text.
• Flashing (2.3.1). Nothing flashes more than three times in any one second.

Most of this is disciplined HTML and a palette checked with a contrast tool, not a redesign. Our Ontario Practice Website Index runs three of these checks (page language, image alt text and text contrast) on Ontario practice homepages, if you want a sense of where sites in your sector stand. Our guides on what a UX audit checks and what a website care plan should include cover how it fits into a review and into ongoing maintenance.

AODA has two enforcement routes. The first is administrative: a director can order an organization to pay an administrative penalty (AODA section 21), and section 83 of the regulation sets the amount from the impact of the contravention and the organization's history. The second is prosecution under section 37 of the Act. As of 15 October 2026:

The offences in section 37 are specific: giving false or misleading information in a report or to a director, failing to comply with a director's or the Tribunal's order, and intimidating or penalizing people who seek enforcement or co-operate with it. A director or officer of a corporation who fails to take reasonable care to prevent the corporation's offence can be fined up to $50,000 a day. For a smaller business the likelier consequence is a compliance order, a complaint, or a site some visitors cannot use.

Section 14 is not a legal requirement for your website. Three things still make building to WCAG 2.0 AA worth it:

1. Growth. If you pass 50 employees in Ontario, the rule applies to the website you already have.
2. Your existing duties. You must offer accessible formats on request and tell the public they are available (section 12). An accessible site makes those requests rarer and easier to meet.
3. Your visitors. Older clients, people with low vision or a tremor, and anyone on a small phone in sunlight benefit from the same fixes.

Accessibility is one of the checks we build into website design and build, and our compliance overview explains how we mark up the rules that apply to your sector.
