About these figures
Source: Ontario’s Public Sector Salary Disclosure (the “Sunshine List”), which names every public-sector employee paid $100,000 or more in a calendar year. Figures are disclosed salaries, not market compensation: anyone in this position earning under $100,000 does not appear, so medians here sit above the true median for the job.
Medians and percentiles use salary paid (benefits excluded), computed over records whose filed job title was normalized into this position. Titles are as each employer filed them; spellings, word order and bilingual forms are merged. Employers and years with fewer than five people show counts only.
