Are you considering a career change or looking to start a skilled trade but worried about the initial paycheck? You are not alone; many aspiring tradespeople hesitate because they are unsure if the financial reward matches the effort required during training. Understanding exactly how much an apprentice plumber makes in Ontario is the first step toward making an informed decision about your future.
The good news is that plumbing offers one of the most structured and transparent pay scales in the labor market. Unlike many entry-level jobs where wages stagnate, plumbing apprenticeships come with guaranteed raises as you gain skills and hours. This guide breaks down the current wage structures, regional differences, and what you can realistically expect to take home in 2026.
How Much Does an Apprentice Plumber Make Per Hour in Ontario?
In Ontario, apprentice plumber wages are not arbitrary; they are typically tied to a percentage of the journeyman (licensed) rate. As of 2026, the average journeyman plumber in Ontario earns between $35 and $45 per hour, depending on the sector (residential vs. industrial) and union status.
Apprentices start at a lower percentage and increase their earnings every year or after completing specific school levels. Here is the general breakdown based on the Ontario College of Trades and common collective agreements:
- Level 1 Apprentice (0–2,000 hours): Earns approximately 50% to 60% of the journeyman rate.
- Estimated Pay: $18 – $22 per hour.
- Level 2 Apprentice (2,000–4,000 hours): Earns approximately 60% to 70% of the journeyman rate.
- Estimated Pay: $22 – $28 per hour.
- Level 3 Apprentice (4,000–6,000 hours): Earns approximately 70% to 80% of the journeyman rate.
- Estimated Pay: $28 – $34 per hour.
- Level 4 Apprentice (6,000+ hours): Earns approximately 80% to 90% of the journeyman rate.
- Estimated Pay: $34 – $40 per hour.
Note: These figures are averages. Unionized positions (such as those under the United Association of Plumbers and Pipefitters) often have higher, strictly defined wage grids that may exceed these non-union averages.
Why the Percentage Model Matters
This progressive pay structure ensures that as you become more valuable to your employer, your paycheck reflects that value. By the time you are close to becoming a licensed journeyperson, you are already earning a competitive wage that rivals many white-collar professions.
What Factors Influence Apprentice Plumber Wages?
While the percentage model provides a baseline, several variables can cause your actual take-home pay to fluctuate. Understanding these factors can help you negotiate better positions or choose the right employer.
1. Union vs. Non-Union
This is the single biggest differentiator in pay.
- Unionized Apprentices: Typically enjoy higher hourly wages, better benefits (health, dental, pension), and job security. The wage steps are clearly defined in the collective agreement.
- Non-Union Apprentices: May have more flexibility in negotiation but often lack the same level of benefits. However, some large non-union construction firms offer competitive packages to attract talent.
2. Location Within Ontario
Cost of living and demand drive wages up in certain areas.
- Greater Toronto Area (GTA): Due to high construction volume and living costs, wages here are generally at the top end of the scale.
- Ottawa & Hamilton: These cities also offer strong wages due to significant infrastructure projects.
- Northern Ontario: While base pay might be slightly lower, remote projects often offer “camp jobs” with additional premiums, housing allowances, and travel pay, which can significantly boost total income.
3. Sector of Employment
- Industrial/Commercial: Often pays higher than residential work due to the complexity of systems (e.g., high-pressure steam, large-scale HVAC integration).
- Residential: May start slightly lower but often offers more consistent overtime opportunities during peak building seasons.

Additional Benefits Beyond the Hourly Wage
When calculating how much an apprentice plumber makes in Ontario, you must look beyond the hourly rate. The total compensation package often includes significant value-adds that improve your financial health.
- Overtime Pay: Construction projects often run behind schedule. Overtime (1.5x or 2x pay) is common, especially in the summer months. An apprentice making $20/hour can make $30/hour for overtime, drastically increasing annual income.
- Health and Dental Benefits: Most union and many large non-union employers provide comprehensive health plans.
- Pension Plans: Contributions to industry-specific pension plans (like the CAAT Pension Plan) are common, securing your long-term future.
- Tool Allowances: Some employers provide an annual allowance for tools, reducing your out-of-pocket expenses.

How to Maximize Your Earnings as an Apprentice
If you want to reach the higher end of the salary spectrum, consider these strategic steps:
- Seek Union Membership: Joining the United Association (UA) can provide access to higher wage grids and better benefits.
- Specialize Early: Show interest in complex systems like medical gas installation, fire protection, or industrial pipefitting. These niches often command higher pay.
- Be Reliable: In the trades, reputation is everything. Showing up on time, eager to learn, and safe on the job site leads to referrals and promotions.
- Complete School Levels Quickly: Some employers tie wage increases to the completion of in-school training blocks. Finishing these promptly can trigger earlier raises.
FAQ: Common Questions About Plumber Wages in Ontario
1. Do I get paid while I am in school for my apprenticeship?
Typically, no. The eight weeks of in-school training per level are usually unpaid. However, you may be eligible for Employment Insurance (EI) during these periods if you have accumulated enough insurable hours. Some employers may offer a partial top-up, but this is not mandatory.
2. Is there a minimum wage for apprentices in Ontario?
Yes. Regardless of the percentage model, all workers in Ontario must be paid at least the provincial minimum wage. As of 2026, if the calculated apprentice rate falls below the general minimum wage, the employer must pay the minimum wage. However, most apprentice rates are well above the minimum.
3. How long does it take to become a licensed plumber in Ontario?
It typically takes 4 to 5 years to complete the apprenticeship. This involves accumulating approximately 8,000 hours of on-the-job training and completing four levels of in-school education (each lasting about 8 weeks).
4. Can I negotiate my starting wage as an apprentice?
In non-union environments, yes. If you have prior construction experience, mechanical aptitude, or relevant certifications (like WHMIS or Working at Heights), you can negotiate a starting wage closer to the higher end of the Level 1 bracket. In unionized settings, wages are fixed by the collective agreement.
5. What is the job outlook for plumbers in Ontario?
The outlook is very positive. With an aging workforce of journeypersons retiring and continuous infrastructure development in cities like Toronto and Ottawa, there is a high demand for skilled tradespeople. This demand helps maintain strong wage growth and job security.
6. Do apprentices receive vacation pay?
Yes. Under Ontario’s Employment Standards Act, apprentices are entitled to vacation pay (typically 4% of gross earnings for the first four years, increasing to 6% after five years). This is usually paid out as you earn it or taken as time off with pay.
Conclusion
So, how much does an apprentice plumber make in Ontario? While you start modestly at around $18–$22 per hour, the trajectory is steep and rewarding. Within four years, you can expect to double your starting wage, reaching $35–$45+ per hour as a licensed journeyperson.
The combination of structured wage increases, overtime potential, and robust benefits makes plumbing one of the most financially stable career paths available today. It requires hard work, physical stamina, and a commitment to learning, but the financial return on investment is clear.
If you are ready to start your journey, research local unions and contractors in your area. Don’t let the entry-level wage discourage you; view it as the foundation of a lucrative lifelong career.
