Legal Age to Work in Ontario — Know the Rules

If you (or your child) are ready to earn a first paycheck, you might be asking:

  • What is the legal age to work in Ontario?
  • Can a 12-year-old work?
  • Where can a 14-year-old work?
  • How many hours can a 16-year-old work?

Let’s break it down in plain English so you know exactly what’s allowed — and what’s not.

What is the Legal Age to Work in Ontario?

In Ontario, the Employment Standards Act (ESA) sets minimum age requirements for different types of work. There’s no single “one size fits all” age — it depends on the job.

Here’s the breakdown:

Type of WorkMinimum Age
General work (retail, offices, restaurants)14 years old
Industrial work (factories, warehouses)15 years old
Construction work16 years old
Logging and mining18 years old

Can a 12-Year-Old Work in Ontario?

Generally, no — not in regular workplaces covered by the ESA.
However, there are exceptions:

For formal jobs, you’ll need to wait until you’re at least 14.

Can a 13-Year-Old Work in Ontario?

Yes — but only in limited, non-industrial settings such as:

  • Offices

  • Retail stores

  • Restaurants (non-hazardous duties)

No work in factories, warehouses, or construction sites until you’re older.

How Many Hours Can Minors Work in Ontario?

The ESA doesn’t set strict limits for hours based solely on age (outside of school attendance requirements), but employers must:

  • Follow Ontario’s rules on daily and weekly maximum hours (usually 8/day or 48/week unless agreed otherwise)

  • Ensure work doesn’t interfere with schooling (compulsory until age 16)

Schools and the Ministry of Labour may place additional restrictions for students.

Where Can a 14-Year-Old Work in Ontario?

Typical jobs include:

  • Grocery store clerk

  • Retail associate

  • Fast food or restaurant worker (front-of-house)

  • Office assistant

They cannot work in areas with industrial machinery or hazardous conditions.

Minimum Age for Construction Work in Ontario

You must be at least 16 to work on a construction site — and even then, employers must provide proper safety training and protective equipment.

How Old Do You Have to Be to Work at a Grocery Store in Ontario?

Most grocery stores hire at 14 years old for roles like cashier, bagger, or stock clerk. Heavy equipment use (like certain slicers or forklifts) may require you to be older.

Key Takeaways for Young Workers and Parents

  • 14 — start in retail, restaurants, or offices.

  • 15 — factories and warehouses open up.

  • 16 — construction work becomes legal.

  • 18 — high-risk industries like mining or logging.

Always remember:

  • Your employer must follow safety laws and give proper training.

  • Young workers have the same employment rights as adults under the ESA.
 

Final Word: Ontario’s legal working age rules exist to protect young workers from unsafe jobs while still giving them a chance to gain experience.
