Legal Working Age in Ontario

The legal working age in Ontario is defined by the Occupational Health and Safety Act (”OHSA”). It outlines different minimum ages for different industries and workplaces. It is not defined by the Employment Standards Act (“ESA”).

What is the minimum legal age to work in Ontario?

In Ontario, the minimum age to work for most jobs is 14 years old. Like all other employees in the province, these young workers are entitled to minimum wage (with certain exceptions for students under 18), holiday pay, and up to three days of unpaid, job-protected sick leave each calendar year.

However, it’s important to note that the legal working age in Ontario varies depending on the industry and workplace. Certain jobs, such as those in construction and mining, may have higher age requirements due to their inherent risks or specialized skill demands. As a result, employees in these industries may need to be older than 14 years old to work legally.

Other Restrictions on the Age of Workers in Ontario

While age requirements are one aspect of minimum age to work in Ontario, it’s also important to account for the educational obligations of those under 18.

Aside from certain exceptions, Ontario’s Education Act states that children must attend school until the age of 18 and that employers are prohibited from employing children younger than 16 during school hours. There are some exceptions to this rule, such as those excused from school attendance under Ontario Regulation 374/10 of the Education Act., “Supervised Alternative Learning and Other Excusals from Attendance at School.

Student Minimum Wage

Student minimum wage applies to students who are under the age of 18 and work 28 hours or less a week during the school term. This is inclusive of scheduled school breaks and summer holidays. Students who work more than 28 hours a week when school is in session are entitled to the general minimum wage.
