Executive Summary: Key Legal and Evidentiary Issues

• Dispute over alleged salary overpayments arising from how monthly “second payments” and gross/net salary adjustments were calculated between May 2022 and December 2023.
• Insufficient and incomplete documentary and testimonial evidence from the employer regarding the alleged overpaid wages, including the absence of testimony from the accountant who prepared the salary tables.
• Contested validity and authenticity of clause 2 of the “Confidentiality, Non-Compete, and Resignation Agreement” dealing with a $6,000 prepayment refund.
• Challenge to the enforceability of the resignation agreement on the basis of a 10-year non-competition clause, and whether that illegality could affect the repayment obligation.
• Factual conflict over whether books and teaching materials purchased and reimbursed by the employer were returned, and the evidentiary impact of the “Entire Agreement” clause.
• Application of the civil burden of proof and the concept of a transaction under article 2631 C.c.Q. to determine which parts of the employer’s claim could succeed.

Background and parties

The case involves GS Commercial of Canada Inc., a company operating in the education sector and related consulting services since 1995, and its former collaborator, Mark-Anthony Timeliadis. GS Commercial’s president, Gefei Zhang, had known Mr. Timeliadis for many years. He initially became involved by offering a few hours of mentoring before progressively increasing his work as a tutor. Over time, he rose to the role of vice-president administrator, a position he held from 8 April 2016 until 10 April 2024. No formal written employment contract governed the relationship. Instead, the arrangement was informal: Mr. Timeliadis was paid by the hour based on the hours he declared, and Ms. Zhang admitted that she never verified his hours before he left in June 2024.

Remuneration structure and alleged overpayments

For the period relevant to the dispute, Mr. Timeliadis received a fixed monthly salary with adjustments claimed as a “second payment.” From May 2022 to April 2023, he was paid a fixed sum of $2,700 per month, later increased to $3,000 per month from May 2023 to December 2023. Each month he emailed the employer to claim a salary “adjustment” based on his hours worked; these adjustments were processed as a second payment. According to the employer, after his departure in June 2024, its accountant, Ms. Yuan, reviewed the payroll and concluded that the adjustments had been calculated on the basis of a gross rather than net salary, so that the employer was effectively reimbursing him, each month, for the income tax and source deductions that had already been withheld. This led GS Commercial to allege an overpayment totalling $10,680.51 between May 2022 and December 2023. From January to June 2024, the parties treated Mr. Timeliadis as self-employed, with payment of the total amount of hours worked and no further monthly adjustment claims.

The employer’s monetary claim and the issues raised

In its small claims action, GS Commercial sought a total of $17,208.42, later reduced to $15,000 to stay within the monetary jurisdiction of the Small Claims Division. The claim was broken down into several components: alleged salary overpayments of $10,680.51; a $6,000 amount the employer said it had prepaid for 2024 benefits and which it alleged Mr. Timeliadis agreed to reimburse in a resignation agreement; and the value of books and other materials, totalling a few hundred dollars, which the employer claimed had not been returned. Mr. Timeliadis contested all heads of claim. He maintained that he had received only the salary owed, denied agreeing to repay $6,000, argued that the alleged $6,000 was in any event his bonus for 2024, and asserted that the employer had unilaterally added the clause requiring repayment without his knowledge after he signed the document. He further argued that the resignation agreement was invalid due to a 10-year non-competition clause. On the materials issue, he stated that he left the books and documents in the employer’s premises when he ceased work at the end of the school session in June 2024, two and a half months after his April resignation.

Burden of proof and assessment of the salary overpayment claim

The Court started from the basic civil law principle that a party asserting a right bears the burden of proving the facts that support its claim, on the balance of probabilities. In a damages or repayment action, the plaintiff must prove fault, loss, and a causal link. If the evidence is equivocal or contradictory such that the judge cannot ascertain where the truth lies, the party bearing the onus fails. Applying this framework, the Court examined the employer’s claim of salary overpayment. GS Commercial produced tables prepared by the accountant, showing the fixed monthly salary and the “second payment” adjustments. The employer’s theory was that by claiming adjustments on a gross basis, the defendant had effectively been paid twice for source deductions, leading to overpayment. However, there were significant evidentiary gaps. The employer did not call the accountant who authored the tables to testify and explain the methodology, the historical basis of the calculations, or any change in treatment before May 2022. Questions remained unanswered, such as how salary was calculated before May 2022, whether Mr. Timeliadis had been treated as self-employed earlier, and whether he was ever clearly instructed to change his calculation method once the alleged error was discovered.

Compounding these gaps, the contemporaneous email exchange from October 2023 suggested that when the employer’s accountant raised a concern about the defendant’s calculations, the employer did not immediately insist on correction for future months. Instead, the employer suggested that the disputed amount could form part of his year-end bonus, acknowledging his hard work and financial needs. There was no evidence of follow-up in November and December 2023, even though the concern about calculation had been flagged. Given this incomplete and somewhat inconsistent picture, the Court found that the employer’s proof was not sufficiently clear and convincing to establish that Mr. Timeliadis had received salary to which he was not entitled. On this basis, the salary overpayment component of the claim was rejected for failure to discharge the burden of proof.

The resignation agreement and the $6,000 prepayment clause

A distinct issue concerned the “Confidentiality, Non-Compete, and Resignation Agreement” signed on 2 April 2024, after Mr. Timeliadis resigned but while he continued to work until June 2024 to finish the session. Clause 2 of this agreement, headed “A refund of the $6,000 prepayment for the year 2024,” stated that Mr. Timeliadis agreed to return $6,000 that the company had prepaid for 2024 benefits, specifying that the prepayment came from 2024 student tuition fees. The defendant attacked this clause on several fronts. He claimed that the clause had been added to the first page after he signed, that his signature appeared only on the second page, and that he had never received a copy of the document. He also argued that the entire agreement was invalid because it contained a 10-year non-competition clause, which he considered illegal, and that the $6,000 was in substance his 2024 bonus, not a repayable prepayment.

The Court examined conflicting evidence about the circumstances of signing. Ms. Zhang testified that the clause was present and discussed when the agreement was executed, and she was supported by a written witness statement from a colleague, Ms. Maina Huminskaya, who described in detail the negotiation and signing process. According to that statement, the parties reviewed and accepted the terms, including the $6,000 refund. Ms. Huminskaya recounted that Mr. Timeliadis expressly agreed to repay the amount, acknowledged that he had contributed less since the birth of his son, and said he would withdraw the funds from his TFSA to make the repayment the same day. She also stated that she printed two copies of the agreement and that all three—Ms. Zhang, Ms. Huminskaya and Mr. Timeliadis—signed both copies, with Mr. Timeliadis taking his copy when he left.

Faced with this version and the defendant’s denials, the Court assessed credibility and probability. It found the account given by Ms. Zhang and corroborated by Ms. Huminskaya more credible and more likely than that of Mr. Timeliadis. The Court concluded that clause 2 was indeed present when the agreement was signed, that the defendant understood and accepted it, and that he knowingly undertook to refund the $6,000. The allegation that the clause had been added later was rejected. The Court therefore held that clause 2 was valid and enforceable and that the defendant was contractually obliged to repay the $6,000 to the employer.

Non-competition clause challenge and severability

Mr. Timeliadis also contended that the resignation agreement was illegal because it contained a non-competition clause with a 10-year duration, which he argued exceeded what the law allows. He sought to use this as a basis to nullify the agreement, including the repayment clause. The Court declined to entertain the validity of the non-competition clause in this proceeding. It noted that the current dispute was not about unfair competition or enforcement of the non-compete, but about repayment of a prepayment. In any event, the Court considered that clause 2 was a separate, self-standing obligation dealing with an entirely different subject matter—the refund of a specific $6,000 advance. Even if the non-competition clause were questionable, it would not taint or invalidate the distinct repayment clause. On this reasoning, the argument based on the alleged illegality of the non-competition provision was dismissed, and clause 2 remained fully operative.

Books, materials and the “Entire Agreement” clause

Another element of the employer’s claim related to books and educational materials. The evidence showed that Mr. Timeliadis had purchased books and school materials and that GS Commercial had reimbursed him, meaning ownership vested in the employer. GS Commercial alleged that the defendant failed to return these items and sought reimbursement for their cost. The defendant testified that at the end of his involvement, on 19 June 2024, he left the books and documents on the employer’s premises. The Court observed that the resignation agreement did not specify any special delivery obligation or precise location where the books had to be returned. On a balance of probabilities, it was plausible that the books were left at the school and may have been used by other teachers.

More importantly, the agreement contained an “Entire Agreement” clause (clause 6), stating that the document constituted the complete agreement between the parties regarding its subject matter and superseded all prior oral and written understandings. The Court characterised the April 2, 2024 agreement as a “transaction” within the meaning of article 2631 of the Civil Code of Québec: a contract by which parties prevent or terminate a dispute by making reciprocal concessions. Because the resignation agreement was a transaction, and because it expressly declared itself to be the entire agreement between the parties on the relevant subject matter, the Court held that neither party could subsequently claim additional amounts for issues not reserved or set out in that agreement. On this basis, the Court refused the employer’s claim for the cost of the books and materials, concluding that this head of claim was barred by the transaction and the Entire Agreement clause.

Overall outcome and monetary award

In the end, the Court accepted the claim only in part. The employer, GS Commercial of Canada Inc., failed to prove any entitlement to repayment of alleged salary overpayments and could not recover for the books and materials, both claims being dismissed for lack of proof and because of the binding effect of the resignation agreement as a transaction. However, the Court upheld clause 2 of the “Confidentiality, Non-Compete, and Resignation Agreement” and enforced the defendant’s commitment to refund the $6,000 prepayment. The judgment therefore orders Mr. Mark-Anthony Timeliadis to pay GS Commercial of Canada Inc. the sum of $6,000, together with interest at the legal rate and the additional indemnity provided by article 1619 of the Civil Code of Québec from 2 April 2024, plus court costs. The decision does not quantify the exact dollar amount of interest, additional indemnity and costs, so the total monetary figure in favour of the successful party—GS Commercial of Canada Inc., on this partial basis—cannot be precisely determined from the judgment itself.
