Mississauga packs in one of the largest concentrations of corporate head offices in the country, so a big share of local organizations clear the 50-employee line. The line is drawn on people, not revenue: 50 or more employees in Ontario. If you clear it, your public website and content posted after January 1, 2012 have needed to meet WCAG 2.0 AA since January 1, 2021. That reaches head offices, logistics and warehousing operators, manufacturers, professional firms, retailers and non-profits right across the city. Under 50 staff, this particular rule doesn't apply to you.

Every municipality is a public body under the regulation, so the City of Mississauga and the Region of Peel carry the WCAG 2.0 AA duty with no size threshold at all — and so do bodies like the local school boards, Trillium Health Partners and MiWay transit. Public sector organizations report on a two-year cycle, and the last deadline, December 31, 2025, has already passed. Ontario.ca asks anyone who missed it to file anyway.

Mississauga has more federally regulated organizations than most cities. Toronto Pearson sits inside the city, and interprovincial transport, banks and telecoms all fall under federal jurisdiction. Those organizations are also covered by the Accessible Canada Act, a separate federal law with administrative penalties of up to $250,000 per violation. The ACA doesn't replace the AODA. A local warehouse is usually a provincial business; an interprovincial carrier usually isn't — which law reaches you depends on how you're regulated, and that's a question for a lawyer.

Ontario's 2023 review found no meaningful enforcement of the AODA, and we won't pretend otherwise. In Mississauga the real pressure tends to arrive through procurement. The City, the Region of Peel and the large head offices based here run accessibility questions through their buying process, so if public bodies or big corporates are in your pipeline, expect to be asked. What usually answers the question is a recent scan report plus a short accessibility statement on your site — proof that you have looked, not a promise that you are perfect.

Mississauga businesses and non-profits with 20 or more employees file an accessibility compliance report by December 31, 2026. At 20 to 49 staff it covers customer service, not your website; at 50 or more, the website duty is part of what you're confirming — so it's worth checking the site before you sign off. Filing is a legal obligation, and Ontario.ca says missing it may lead to potential enforcement action.

Canadian consultancies quote CAD $2,400 to $25,000 for a one-time audit. Before spending anything like that, run the free automatic scan. It maps your site against WCAG 2.0 AA and finds the machine-detectable problems — about 57% of issues by volume (Deque, 2021) — things like missing image descriptions, faint text and unlabelled form fields. The parts that need a person, such as keyboard flows and screen-reader behaviour, it flags honestly instead of hiding. You end up knowing how much work you're really looking at before you spend a dollar.
