Corrections

If a result or explanation on tools.tnaado.ca is wrong, email contact@tnaado.ca. TNAADO Inc. is responsible for reviewing reports about this site.

What to include

• The page address and the part that appears wrong.
• The result you expected and the result you got.
• A small example using made-up values, plus your browser if the issue concerns a download or display.
• A link to the official source when a rule, threshold or date has changed.

Do not send passwords, account or identity numbers, private files, or other sensitive information. A screenshot or sample should hide personal details.

What happens next

We check whether we can reproduce the issue and compare factual reports with their source. Confirmed errors are corrected in the calculation, explanation or data. A material change should include an updated date and, where needed to explain the change, a correction note.

We cannot promise a response time or a particular outcome. A feature request is different from a correction; you can still send one through Contact.

What a correction cannot do

We cannot change a government decision, financial transaction or third-party record. Our tools produce information and drafts, not professional representation or official approval.
