What the Act says

The Act respecting labour standards contains provisions concerning overtime that protect the majority of Québec workers, whether they are full or part time.

Length of the normal workweek

The normal workweek usually lasts 40 hours. Its length serves to determine the point in time from which an employee begins to work overtime.

However, for some employees the normal workweek is not  40 hours:

Length of the normal workweek

Employees of the clothing industry

39 hours
Watchmen who guard a property on behalf of a firm providing surveillance services44 hours
Employees working in a forestry operation or a sawmill  47 hours
Employees who work in a remote area or on the James Bay territory55 hours
Watchmen who do not work for a firm providing surveillance services60 hours

The normal workweek is not a period of time beyond which an employee may refuse to work.

Calculation of overtime

The hours worked in addition to the hours of the normal workweek must be paid with a 50% premium in addition to the regular hourly rate (time and a half), without counting the premiums available on an hourly basis such as night shift premiums.

At the employee’s request, the employer may replace the payment of overtime with a leave of an equivalent duration of the overtime hours worked, increased by 50% (7 hrs = 10 hrs 30 min.).

The annual vacation and statutory holidays are considered days worked for the purposes of calculating overtime.

For some employees, it is the initial agreement that establishes the point in time when they begin to work overtime:

Agreement with a specific number of hours per week

An employee hired for fixed wages to work a predetermined number of hours and who is able to define an hourly rate by dividing the wages by the number of hours worked stipulated in his agreement would seem to be an employee paid at an hourly rate. Hours worked beyond 40 hours should be increased by 50%.

Agreement without a minimum or maximum limit on the number of hours per week

If the agreement stipulates a fixed amount for working an unlimited number of hours of work, with no minimum or maximum, the employer cannot deduct the missing hours if the employee did not work at least 40 hours.

How to calculate the indemnity

The Commission des normes, de l'équité, de la santé et de la sécurité du travail provides employers and employees with access to monCalcul, a tool designed to help calculate the amounts to which an employee is entitled according to the type of compensation in effect.

Staggering of working hours

If the Commission des normes, de l'équité, de la santé et de la sécurité du travail gives its authorization, an employer may stagger the working hours over several weeks. The authorization must be posted in the workplace of the employees affected. This authorization from the Commission is not necessary when the staggering of working hours is stipulated in a collective agreement or a decree.

Right to refuse to work

An employee may refuse to work if, on a given day:

  • he is asked to work more than 4 hours beyond his regular hours or more than 14 hours per 24-hour period, whichever period is shorter
  • he is asked to work more than 12 hours per 24-hour period.
    This provision only applies to employees whose daily working hours are variable or non-continuous.

An employee may also refuse to work if, in a given week:

  • he is asked to work more than 50 hours, except if his working hours are staggered
  • he is asked to work more than 60 hours. This provision only applies to employees who work in a remote area or, more specifically, on the James Bay territory.

An employee cannot refuse to work:

  • in the case where the life, health or safety of workers or the public is endangered
  • in the case of a risk of destruction of or serious damage to property and buildings, or in another case of superior force
  • if this refusal violates his professional code of ethics.

Differences in conditions of employment

An employer cannot give an employee who is subject to the Act respecting labour standards conditions of employment that are less advantageous than those of other employees doing the same work in the same establishment due to his hiring date.

These conditions of employment notably deal with:

  • wages
  • length of work
  • paid statutory holidays
  • annual vacation
  • rest periods
  • absences and leaves for family or parental reasons
  • notice of termination of employment.

The standard concerning time and a half does not apply to:

  • a student employed in a vacation camp or a social or community non-profit organization such as a recreational organization
  • the managerial personnel of an enterprise
  • an employee who works outside the establishment and whose working hours cannot be controlled
  • an employee assigned to canning, packaging and freezing fruit and vegetables during the harvest period
  • an employee of a fishing, fish processing or fish canning industry
  • a farm worker
  • an employee whose exclusive duty is to take care of or provide care to a child or to a sick, handicapped or elderly person, in that person's dwelling, including, where so required, the performance of domestic duties that are directly related to the immediate needs of that person, unless the work serves to procure profit to the employer.
