If your nanny works overtime, you should plan on compensating her for her time.
Nannies who work more than 40 hours(some province it's 44-45 hours) within a 7-day workweek must get overtime pay, according to the ministry of labor.
You should plan on paying overtime pay for nannies at a compensation rate of 1.5 times your nanny’s hourly wage.
Overtime pay for nannies can be built into the salaries. For instance, a nanny who works a 50-hour workweek might get a lump wage based on an hourly rate of 40 hours plus 10 hours of overtime pay.
A nanny can work as many hours as you and she agree upon. (Not more than 12 hours in a day) Although nannies who are live-in often get paid less, they do have the right to get pay equal to that of a live-out.
