Method. Medians and averages are salary paid; listed payroll is total compensation (salary plus taxable benefits), as filed. Both sides come from the same Ontario Sunshine List, which covers only public-sector employees paid $100,000 or more — so this compares the shape of each employer’s six-figure payroll, not its whole workforce, and an employer with more low-paid staff simply lists fewer of them. A side with fewer than five people keeps its count but shows “<5” instead of a median, average or payroll figure, since any of those would be that handful of people’s own numbers. Sector: Crown Agencies. Data runs through 2025.
