Maintenance Supervisor Salary in Hamilton, ON (2026)

Based on aggregated data from Indeed, Glassdoor, PayScale, and ERI (2025-2026), the average Maintenance Supervisor salary in Hamilton, ON is approximately $83,000 CAD per year. The full range runs from around $58,000 CAD at entry level to $125,000 CAD for principal or maintenance manager roles. Figures represent base salary only and exclude shift premiums, on-call pay, and bonuses.

Industrial plant settings in Hamilton - including steel, food processing, and auto parts manufacturing - typically pay 10-20% above property or facilities management roles. Senior plant supervisors with a Red Seal ticket and CMMS ownership commonly earn between $95,000 and $115,000 CAD. Shift differentials and on-call premiums can add a further $5,000-$12,000 CAD annually on top of base.

The clearest pay drivers are a Red Seal or provincial journeyperson trades ticket (millwright, industrial electrician, pipefitter), proficiency in an enterprise CMMS platform (Maximo, SAP PM, eMaint), and the CMRP designation. Supervisors who hold both a trades certificate and documented CMMS outcomes consistently negotiate into the upper half of their experience band. Team size, union environment, and shift accountability also factor significantly into where you land within a range.

$80,000 CAD sits within the mid-career band and is at or slightly above the median for Hamilton-area Maintenance Supervisors across all sectors. It is a fair benchmark for someone with 5-8 years of experience managing a mid-sized team in a manufacturing or facilities setting. Supervisors in industrial plant environments with trades certification and CMMS ownership should be targeting $90,000+ at this stage of their career.

In Hamilton's industrial market, Maintenance Supervisor typically describes a role with direct hands-on team leadership and shift accountability, while Maintenance Manager implies site-wide or multi-department program ownership and budget authority. The salary gap between the two is roughly $15,000-$25,000 CAD, with managers generally landing between $108,000 and $125,000 CAD at senior levels. The transition usually requires demonstrated capital project leadership and reliability program ownership.

Not necessarily more base salary, but unionized environments at major Hamilton employers often come with defined pay grids, stronger pension contributions, and structured shift premiums that meaningfully increase total compensation. Non-union private-sector plant roles can exceed union base rates at senior levels but with less predictable total-package security. Candidates should compare the full package - base, premiums, pension, and benefits - rather than base pay alone.

Toronto's market is broader and has a higher ceiling, with top-earner data showing up to $136,000 CAD, compared to roughly $125,000 CAD at the top end in Hamilton. However, Hamilton's industrial-sector roles are often more competitive on base than Toronto's property management roles, and the cost of living differential makes Hamilton's mid-career band ($70K-$90K) go further in practice. Supervisors targeting the top of the market in either city should focus on industrial or institutional settings rather than residential property roles.
