Note:  Some oilwell servicing employees (e.g. water, steam, and vacuum truck operators) may be subject to either the federal or provincial Drivers' Hours of Service Regulations, which govern the maximum driving times and minimum off-duty times of commercial vehicle drivers (both bus and truck).

Days of rest

Employees must receive at least 4 days of rest that is free from on call duties in each 28-day period, unless the employee specifically agrees to be on call.

When travel time is work

When an employer directs an employee in how to travel to the worksite, for example, requiring an employee to take the company bus, the time spent travelling to the worksite becomes work for both the driver and any passengers.

Travel time is work when an employee, whether driver or passenger, goes from:

  • the employer’s business or a place designated by the employer to a worksite and return, or
  • one job site to another job site

Travel time is not work when an employee:

  • is given the choice of travelling from their residence to the worksite on their own, with a co-worker or using transportation provided by the employer

When on call is work

Being on call is generally not considered to be work and wages aren’t payable for on call time, although the employer and employee can agree to some form of pay.

Example: An acceptable on call arrangement that isn’t work is where an employee carries a pager during non-work hours.

An employee is considered to be working and owed wages when an employer places additional responsibilities on the employee during on call periods, such as wearing of uniforms or continuously monitoring radio calls which aren’t solely for that employee.

When standby is work

An employee is considered to be working when directed by the employer to wait at the worksite (on standby).

Bonus payments

  • A bonus must be paid in the same manner as normal wages; within 10 days after the end of the pay period subsequent to the one in which the bonus was earned.
  • When an employee is paid a combination of salary and a bonus:
    • a bonus is not considered to be wages when calculating general holiday pay
    • the employee’s wage rate is considered the minimum wage used to calculate the minimum entitlement to overtime pay and pay for time worked on a general holiday
  • Vacation pay is payable on the entire salary portion, and portion of the bonus remaining, after subtracting overtime (calculated using the employee’s wage rate as the hourly rate).
