The Ontario tax sale tender process is governed by O. Reg. 181/03 (Municipal Tax Sales Rules) under the Municipal Act, 2001. Bidders submit a sealed Form 7 (Tender to Purchase) with a deposit of at least 20% of the bid, paid by money order, bank draft, or certified cheque. The sealed, correctly marked envelope must be delivered before the tender closing time — late tenders are always rejected. Tenders are opened publicly and the highest valid bid above the minimum tender amount wins. The winner pays the balance plus land transfer tax and HST (where applicable) within 14 days, after which the municipality registers a Tax Deed. There is no post-sale redemption right in Ontario.
Ontario Tax Sale Tender Process: How to Submit a Winning Sealed Tender
In Ontario, tax sale properties are won or lost on paperwork. Because bids are submitted by sealed public tender — not a live auction — there is no second chance to react to competitors. A single formatting mistake, a personal cheque instead of a certified one, or a delivery that arrives one minute late will disqualify an otherwise winning bid. This playbook walks through the exact tender mechanics under O. Reg. 181/03 (the Municipal Tax Sales Rules) made under the Municipal Act, 2001, so your tender is accepted on the first try.

Before You Tender: Confirm the Details
Every Ontario tax sale must be advertised in The Ontario Gazette at least 60 days before the tender closing date, and on the municipality's website. Before you prepare anything, obtain the municipality's tax sale package for the specific property and confirm four things:
- Minimum tender amount (upset price): your bid must equal or exceed it. It covers arrears, interest, penalties, and costs — not market value.
- Tender closing date and exact time: down to the minute, and the precise delivery address.
- Legal description and roll number: copy these exactly as they appear in the advertisement.
- Any property-specific instructions: deposit form, envelope marking, and whether HST may apply to the sale.
Do your due diligence now — title search, MPAC assessment, zoning, and road access — because once you win, the sale is final. Ontario has a 1-year cancellation period before the sale but no post-sale redemption right.
The Ontario Tender Process, Step by Step
Step 1 — Obtain the official Form 7 (Tender to Purchase)
Ontario bids must be made on Form 7, the prescribed “Tender to Purchase” under O. Reg. 181/03. Many municipalities include Form 7 in their tax sale package or on their website. Use the official form — a home-made or altered form risks rejection.
Step 2 — Prepare your deposit (at least 20%)
Your tender must be accompanied by a deposit of at least 20% of your tender amount. The deposit must be by money order, bank draft, or a cheque certified by a bank, trust corporation, or credit union. Personal cheques and cash are not accepted. Make it payable to the municipality exactly as instructed in the package.
Step 3 — Complete Form 7 exactly
Fill in the property's legal description and roll number precisely as advertised, and enter your tender amount. Your bid must be equal to or greater than the minimum tender amount. Do not alter the pre-printed wording of the form. Double-check for arithmetic and transcription errors — the amount in your tender is binding.
Step 4 — Seal and mark the envelope
Place the completed Form 7 and the deposit in a sealed envelope. The envelope must be marked as the municipality instructs — typically with the words “Tax Sale” and a short description or roll number of the property, and without your bid amount showing on the outside. Follow the exact marking instructions in your tax sale package; if in doubt, confirm with the municipal treasurer's office.
Step 5 — Deliver before the closing time
Deliver the sealed envelope to the specified address before the closing time. This is the single most important rule: late tenders are rejected without exception, and mail delays are your risk, not the municipality's. Whenever possible, deliver in person and get a time-stamped receipt, or courier with a healthy buffer.
Step 6 — The public tender opening
At the closing, all valid tenders are opened publicly. The highest valid tender above the minimum tender amount wins. Losing bidders' deposits are returned. If only one valid tender is received, that bidder wins; if none are valid, the municipality may re-advertise.
Step 7 — Pay the balance and take title
The winner must pay the balance of the tender within 14 calendar days, along with any accumulated taxes, land transfer tax, and HST where it applies. The municipality then registers a Tax Deed transferring title, extinguishing most prior encumbrances (with limited exceptions such as certain Crown interests and easements). If the winner fails to pay, the deposit is forfeited and the property may be offered to the second-highest tenderer.

Common Mistakes That Disqualify Ontario Tenders
- Late delivery — the number-one disqualifier. The clock, not your intent, decides.
- Wrong deposit form — a personal cheque or cash instead of certified funds.
- Deposit under 20% — even slightly short means rejection.
- Bidding below the minimum tender amount — automatically rejected.
- Altered or incomplete Form 7 — changed wording, missing roll number, or unsigned.
- Envelope marked incorrectly — not following the municipality's exact instructions.
💡 Investor Tip: Because you can't see rival bids, decide your maximum in advance from comparable sales, then submit a number you're happy to win at — not a round figure. On rural lots the winning tender is often only slightly above the minimum tender amount, so a small, well-researched premium frequently takes the property.
