Time Off in Lieu vs. Overtime Pay: Do You Have to Accept Banked Hours?

Overtime creates a debt. Your employer can settle that debt in one of two currencies: money (the overtime rate) or time (paid time off). Time off in lieu is simply the second currency. The catch is that the law fixes both the exchange rate and the deadline for spending it — and if the deadline passes with the time unspent, the debt reverts to money.

The exchange rate is the same idea everywhere: an hour of overtime is not worth an hour off. It is worth an hour and a half off, mirroring the 1.5× pay rate.

Under the Canada Labour Code, an overtime hour entitles you either to pay at not less than 1.5× your regular rate or to "not less than one and one-half hours of time off with pay for each hour of overtime worked" (s. 174(1)(b)). Two things matter here.

First, banking is at the employee's request, on a written agreement — it is not something the employer can simply impose in place of pay. Second, the time off must be taken within three months of the pay period in which the overtime was worked, or within a longer period agreed in writing — at most 12 months outside a collective agreement (s. 174(3)).

And here is the protection that matters most: if you do not take the banked time within that period, the employer must pay it out as overtime, at 1.5×, within 30 days (s. 174(4)). The same rule applies if your employment ends before you take the time — it is paid out within 30 days of termination (s. 174(5)). Banked hours do not evaporate. They convert back to cash.

In Ontario, the Employment Standards Act, 2000 allows an employee and employer to agree that overtime will be compensated with paid time off instead of pay — again at the rate of one and one-half hours off for each hour of overtime worked (s. 22(7)). The essential word is agree: lieu time in Ontario rests on an agreement, not on the employer's unilateral decision. Absent that agreement, the default remains overtime pay at 1.5× above 44 hours in the work week (s. 22(1)).

Québec's Loi sur les normes du travail frames the same choice. Article 55 provides that, "à la demande de la personne salariée ou dans les cas prévus par une convention collective ou un décret," the employer may replace payment of overtime with paid leave equal to the overtime hours worked, "majorée de 50 %" — that is, increased by 50%, the time equivalent of the 1.5× rate. That leave "doit être pris dans les 12 mois suivant les heures supplémentaires effectuées" (art. 55, para. 3).

If the compensatory leave is not taken within those 12 months, the monetary debt survives: you are still owed the overtime. In Québec, too, banking is normally at the employee's request (or under a collective agreement or decree) — not a substitute the employer can force.

Put the three regimes together and one principle stands out. Time off in lieu is a way to defer the debt, not to cancel it. If the banked time was never taken within the legal window — three months (extendable to 12) federally, 12 months in Québec, or the term of the agreement in Ontario — then the hours convert back into a wage claim at 1.5×.

So if you agreed to bank hours a year ago, never got to take them, and then were told "the year is up, you lost them," that is very likely wrong. Federally, those hours should have been paid out within 30 days of the period ending. The same logic applies if you leave a job with a bank of untaken lieu time: it is payable.

• Check whether the request came from you. Federally and in Québec, lieu time is normally at the employee's request. If banking was imposed as a way to avoid paying overtime, question it.
• Note the deadline in writing. Three months federally (up to 12), 12 months in Québec. Diarise it.
• Keep your own record of the bank. Track hours banked and hours actually taken. The gap is what may still be owed.
• Do the math on conversion. Untaken banked hours are worth 1.5× your regular rate in cash — not your plain hourly rate.
