Anonymised, illustrative composite. A national buyer applied 4%, stepping to 6% at five years, to every employee it acquired. In Saskatchewan the rates are three fifty-seconds and four fifty-seconds, the step is at ten years, and vacation pay is itself part of the base.
At a glance
The buyer acquired a multi-province industrial services business through a share purchase with a completion-accounts mechanism and a net working capital peg set on a normalised twelve-month average. Accrued vacation was one of the largest current liabilities on the target's balance sheet, and the buyer's model rebuilt it from the payroll register rather than accepting the target's figure — which was the right instinct, applied with one rule for the whole country.
Ontario and British Columbia both step from four per cent to six at five years' service. Under ESA s.35.2 an Ontario employer pays vacation pay equal to at least “4 per cent of the wages, excluding vacation pay, that the employee earned during the period for which the vacation is given, if the employee's period of employment is less than five years”, and at least “6 per cent of the wages, excluding vacation pay, that the employee earned during the period for which the vacation is given, if the employee's period of employment is five years or more”. British Columbia's Employment Standards Act s.58(1) is materially parallel: at least 4% after five calendar days of employment and, at paragraph (b), “after 5 consecutive years of employment, at least 6% of the employee's total wages during the year of employment entitling the employee to the vacation pay”.
Saskatchewan is the outlier on all three of the variables that matter — the rate, the step, and the base — and the model got all three wrong at once.
The Saskatchewan Employment Act states the entitlement in weeks and the pay in fractions. Section 2-24(1) entitles every employee “to an annual vacation of three weeks after the completion of each year of employment with an employer” and “to an annual vacation of four weeks after the completion of 10 years of employment with an employer and after the completion of each subsequent year of employment with that employer”. Section 2-27(1) then sets vacation pay at “three fifty-seconds of the employee's wages for the year of employment or portion of the year of employment preceding the entitlement to the vacation” at the base tier, and “four fifty-seconds of the employee's wages for the year of employment preceding the entitlement to the vacation” at the ten-year tier. Three fifty-seconds is 5.769%; four fifty-seconds is 7.692%.
The Saskatchewan payroll of $5,120,000 divided into $2,180,000 for 41 employees under five years' service, $1,960,000 for 22 employees between five and ten years, and $980,000 for 11 employees over ten years. Accrued correctly that is $125,769 plus $113,077 plus $75,385, or $314,231. Accrued on the buyer's national rule it is $87,200 plus $117,600 plus $58,800, or $263,600.
The net gap of $50,631 conceals its own composition. The under-five group was understated by $38,569, because 4% against 5.769% is an understatement of about 44%. The five-to-nine group was overstated by $4,523, because Ontario's 6% is higher than Saskatchewan's 5.769% — the two curves cross in that band. The ten-plus group was understated by $16,585. A buyer that checks the total and finds it roughly right has checked the one number that hides the error.
The base is the third variable and it is the one nobody models. Ontario's s.35.2 is explicit that the percentage applies to wages “excluding vacation pay”. Saskatchewan's definition runs the other way: s.2-1 defines “wages” to mean “salary, commission and any other monetary compensation for work or services or for being at the disposal of an employer, and includes overtime, public holiday pay, vacation pay and pay instead of notice”. So the Saskatchewan fraction is applied to a base that expressly includes overtime, public holiday pay and vacation pay itself. On a workforce with meaningful overtime, the effective gap between the two provinces is wider than the headline 4% against 5.769% suggests.
The payment deadlines differ too, and they matter at closing. Saskatchewan s.2-27(2) requires vacation pay to be paid to an employee who does not take the vacation “not later than 11 months after the day on which the employee becomes entitled to the vacation”, and s.2-29(1) requires that on the end of employment “the employer shall pay to the employee the vacation pay to which the employee is entitled pursuant to this Part within 14 days after the day on which the employment ends”. A buyer planning a post-closing reduction in a Saskatchewan location is on a fourteen-day clock for the accrual it has just mis-stated.
The last piece is why the error survived the deal mechanics. The peg and the closing statement were both built from the same accrual policy. A completion-accounts true-up compares two balance sheets prepared on a consistent basis, so a systematic error in the policy nets to zero in the adjustment and passes through untouched. It does not show up as a purchase-price variance. It shows up when the balance is paid.
The accrual model was rebuilt province by province before completion accounts were finalised, and the target's own figure — which had used the correct Saskatchewan fractions all along — turned out to be right. The peg was reset upward by $50,631 on the Saskatchewan payroll, and the buyer added a standing note to its integration template that vacation accrual is a per-jurisdiction parameter rather than a company-wide one.
The buyer also discovered that the four-week entitlement at ten years is a scheduling liability as well as a cash one: eleven employees in one Saskatchewan location were entitled to four weeks each while the buyer's shift model had been built on three.
The cash cost of the error was $50,631 on this payroll, which on a $23,500,000 deal is not material on its own. The cost of the assumption behind it is not bounded by this deal. The buyer had already made two acquisitions on the same template and planned four more, and the same rule would have been applied to Manitoba, Alberta and the Atlantic provinces without anyone checking those statutes either. What was actually bought here was a corrected template.
The tell was a single field. One payroll system, one accrual-rate parameter, three provinces. Any model that carries one rate for a multi-province workforce is asserting that the statutes agree, and the fastest way to test the assertion is to read the one that states its rate as a fraction rather than a percentage.
