По закону Онтарио запрещается работодателю, чтобы его работник работал более 48 часов в неделю. На это надо специально договорится
Weekly limit
The maximum number of hours most employees can be required to work in a week is 48 hours. The weekly maximum can be exceeded only if there is an electronic or written agreement between the employee and employer.
An agreement between an employee and an employer to work additional daily or weekly hours, does not relieve an employer from the requirement to pay overtime pay where overtime hours are worked.
