Your letter includes a firm deadline. Do not engage in informal text messages during this time.
If they miss the deadline, you have completed the required out-of-court steps. Hand this complete paper trail to a local attorney for litigation.
The Assessment You Are Objecting To
Filing preserves your right of objection. The 180-day clock under the Taxation Act 2007 (and parallel provisions in the other MOF-administered statutes) runs from the date the Notice of Assessment / Reassessment / Statement of Disallowance was mailed or personally delivered. IFTA assessments have a tighter 30-day window. If you missed the deadline, an extension up to 1 year is possible on a showing of impossibility.
This letter will cite
Taxation Act 2007 (S.O. 2007, c.11 Schedule A) — primary objection framework; parallel objection provisions in Employer Health Tax Act, Retail Sales Tax Act, Fuel Tax Act, Gasoline Tax Act, Tobacco Tax Act, Mining Tax Act, Land Transfer Tax Act; LSO By-Law 4 (UPL framing for self-represented filers).
Your letter is the substantive equivalent of any required notice-of-objection form and identifies the assessment, the disputed amount, the grounds, and the relief sought. MOF will accept the letter via online portal, mail, fax, or in-person delivery to any MOF tax office.
180-day clock under most MOF statutes. IFTA: 30 days. Extension to 1 year is possible under the relevant statute's extension provision on a showing of impossibility.
Total of tax + interest + penalty you are contesting. If you accept part of the assessment, state the unchallenged portion in the narrative.
Plain-language facts: what happened, why the assessment is wrong, what evidence supports your position.
Before you start
What exactly do I get, and when?
A personalized PDF letter, written around the statute that applies to your situation, with the deadline and the consequence spelled out. It downloads the moment payment confirms, back here on commoner-law.com — there is no waiting period and no account to create. You can also add certified mail at checkout and we will send the physical letter for you.
How much is it?
$19, once. Not a subscription, and nothing is charged until you complete payment on Stripe at the end of the wizard. Any add-ons you select show their own price before you pay.
Is this legal advice?
Self-help template; not legal advice. The Ontario MOF objection process is designed for self-filers; filing is FREE. Self-representation at MOF administrative stages is permitted. For appeal to the Superior Court of Justice / Tax Appeals Board after the Notice of Decision, retain an LSO-licensed lawyer (paid representation by non-licensees is restricted under Law Society of Ontario By-Law 4).
What if I need to change something afterwards?
Tell us and we will either adjust the letter and send you the updated version at no cost, or refund you in full — your choice. If we can’t deliver what you paid for, the refund is automatic. Full terms are on our promise page.
Do I have to pay to know if I have a case?
No. The rights encyclopedia on this site is free and cites the same primary sources the letter does. Read the relevant guide first — plenty of situations are resolved by a phone call to a free statutory body, and where one exists we say so.
