What if a customer edits an e-signed bill of sale? UCDA's September warning, read against O. Reg. 333/08

The United Car Dealers Association (UCDA), a dealer trade association, carries in its September 2026 Front Line newsletter (Vol. 39 No. 08) a short item on a risk a member raised: a customer can change a proposed bill of sale before signing it, and the dealer may not notice. The newsletter’s example has a dealer sign a bill of sale electronically and send it, and the customer edit it before signing without saying so. Two clauses are gone when it comes back. One is the Sales Final clause. The other let the dealer recover its damages from the customer’s deposit if the customer did not complete the purchase. UCDA’s advice starts with “Never assume that the contract you receive back is the same one you sent out.” Compare the two before treating the deal as done, and use a secure electronic signature platform, or a file format the customer cannot edit, so a change is harder to miss.

The newsletter says the Motor Vehicle Dealers Act, 2002 requires certain terms on a bill of sale and that Sales Final is one of them. The requirement is in the general regulation under that Act, O. Reg. 333/08, and the sections below read the newsletter’s example against it.

Where is the Sales Final statement required?

For a new vehicle, paragraph 24 of section 39(2) requires the contract to carry, on the same page as the purchaser’s signature and next to it, the statement set out in section 39(3), in 12 point bold font with a 14 point bold heading. The wording is fixed:

Sales Final

Please review the entire contract, including all attached statements, before signing. This contract is final and binding once you have signed it unless the motor vehicle dealer has failed to comply with certain legal obligations.

For a used vehicle, paragraph 1 of section 40(2) brings in paragraphs 21 to 27 of section 39(2), so paragraph 24 and the same statement apply. Both sections cover a sale to a purchaser who is not another registered dealer.

The duty is the dealer’s. Section 39(2) opens with “A registered motor vehicle dealer shall ensure that any contract that the dealer enters into” includes the listed items, and section 40(2) is worded the same way. UCDA’s newsletter says the customer’s change “could have placed the dealer in breach of the MVDA”, and the wording supports that reading: a customer can delete the statement from a draft, but the regulation asks whether the contract the dealer entered into carries it.

Is a clause keeping the deposit a required term?

No. Paragraph 17 of section 39(2) requires the contract to show the down payment or deposit, if any, and none of the section’s 27 paragraphs requires a clause about damages or keeping a deposit. What the regulation does require, in section 39(9) for new vehicles and section 40(8) for used ones, is that a contract include “all restrictions, limitations and conditions imposed on the purchaser under the contract” in a clear, comprehensible and prominent manner. That wording reads as reaching a deposit clause the dealer means to rely on, which would put the clause in the contract where the customer can see it.

What a dealer may keep when a signed buyer walks away is covered by OMVIC’s own guidance on cancelled agreements, summarised in our post on Ontario’s lack of a cooling-off period.

Was there a contract at all?

That is UCDA’s second point, and it rests on contract law rather than on the MVDA. The newsletter’s reading is that a customer who changes important terms before signing may be making a counteroffer rather than accepting the dealer’s offer, and that if the dealer never agreed to the new terms, “a court could find that no binding agreement was ever formed.” Neither the Act nor O. Reg. 333/08 addresses offer and acceptance, so that part is the association’s view of the general law and not something the dealer statute decides.

What does the regulation say about signing?

It says who signs and when the buyer gets a copy, and nothing about the medium. For a new vehicle sale, section 39(10) makes the dealer ensure the contract is signed by the parties, is signed by the registered salesperson if one acted on the sale, and that the purchaser “receives a copy of the contract immediately after signing it”. Section 40(9) says the same for used vehicles. O. Reg. 333/08 does not mention electronic signatures. The MVDA lists governing the application of the Electronic Commerce Act, 2000 among the subjects regulations may cover, in paragraph 44 of section 44(1), and O. Reg. 333/08 does not take that up.

Does a lease carry the same statement?

No. Section 41(1) lists what a lease must include, and its three prescribed statements are headed “Important Information Respecting Motor Vehicles Leases”, “Canadian Motor Vehicle Arbitration Plan” and, where a current certificate is provided, “Safety Standards Certificate”. There is no Sales Final statement in the lease section. The signing rules match the sale sections: section 41(9) requires the lease to be signed by the parties and the lessee to receive a copy immediately after signing.

Where this sits in exam study

What a sale contract must contain is the contracts section of this site’s practice bank, and the contracts practice page works through the lists in sections 39 and 40. Paragraph 24 fixes both the words and where they sit: beside the purchaser’s signature, on the same page.
