Ontario businesses and non-profits with 20 or more employees file by December 31, 2026. It's every three years; the last was 2023 and the next will be 2029. Public-sector organisations are on a two-year cycle and were due December 31, 2025.
Create an account on the Accessibility Compliance Reporting Portal, start a new submission, answer the yes/no questions for your size, name the certifying officer, and submit. There's no fee. The portal is slowest in the last week of December, so registering in the autumn is the practical move.
On paper, the Act allows administrative penalties of up to $100,000 per day for a corporation and $50,000 per day for an individual, and directors or officers who direct or acquiesce in non-compliance can be personally liable.
In practice, public reporting describes Ontario's enforcement as light: the maximum has never been used, only a handful of fines have been issued over several years, and the regime rests almost entirely on self-reporting. Anyone telling you a fine is imminent is selling something.
The real risk is narrower and more personal: a certified report that says "yes" where the truthful answer is "not yet" is a false statement to a regulator with an officer's name on it. That's the thing to avoid, and it's avoidable by checking each answer before signing.
File anyway. The obligation doesn't expire; a late filing is a manageable problem, a missing one is an open one. Public-sector organisations that missed the 2025 date are still required to file.
