How we use automated decision-making

Some of the decisions this service makes about your property are made by an automated system without a person looking at them first. Quebec’s Law 25 requires us to tell you when that happens, and to let you ask a person to review it. We apply that right everywhere, not only in Quebec.

What is decided automatically

Whether your assessment looks out of line with similar homes nearby; which homes count as similar; the estimated saving; and whether we recommend filing. The comparison itself is arithmetic on public assessment data — the system does not invent any of the numbers.

What information is used

Your address, the public assessment record for it, the characteristics on file, anything you correct or tell us, and the public assessment records of comparable properties.

Your right to a human review

You can ask a person to review any recommendation or decision, at any time, without giving a reason. You will get the reasoning behind the original result and a person’s view of it.

What is never automated

A person authorises every filing. In Ontario, a licensed representative signs off on anything filed with the Assessment Review Board. No number in anything we file or send you is written by a language model — every figure comes from a calculation we can show you.
