Ontario open data
A deliberate source map for public salary intelligence
make100k should help people understand public money in Ontario, not bury them in scraped pages. This registry shows the official datasets we use or are evaluating, the value each source can create, and the gate it must clear before it changes a public page.

Live source
This is the source make100k already transforms into the salary graph.
Public Sector Salary Disclosure
Live in productTreasury Board Secretariat
- Value for Ontarians
- Shows who is disclosed at $100,000 or more, by employer, title, salary, benefits, and year.
- make100k use
- Core salary graph: people, employers, titles, cities, sectors, trajectories, ranks, and medians.
- Join key
- person name, employer name, title, disclosure year
- Limitations
- Only includes employees over the statutory threshold. It is not a complete labour-market compensation dataset.
Quality gate
Annual row counts, addenda handling, no-salary organization files, entity-resolution flags, and source-year provenance must pass before publication.
Ready next
These are the strongest next joins because they add spending, school-board, and municipal context people can actually use.
Public Accounts: Detailed Schedule of Payments
Ready nextTreasury Board Secretariat
- Value for Ontarians
- Adds payment context around ministries, transfer recipients, suppliers, and public spending flows.
- make100k use
- Employer and sector pages can show salary disclosure beside disclosed public payments without implying causation.
- Join key
- organization name, ministry, fiscal year
- Limitations
- Payments are not payroll rows and should not be used to infer individual compensation or performance.
Quality gate
Recipient aliases must be resolved separately from salary employer aliases, and all joins need a confidence label.
School board financial reports
Ready nextMinistry of Education
- Value for Ontarians
- Shows school board revenue and expense context behind public-sector education payroll trends.
- make100k use
- School-board employer pages can add spending, grant, and staffing context around disclosed salary counts.
- Join key
- school board name, board identifier, fiscal year
- Limitations
- Board financial years and salary disclosure calendar years do not always align directly.
Quality gate
Fiscal-year alignment, board alias mapping, and per-pupil or expense ratios must be documented before display.
College graduate outcomes survey
Ready nextMinistry of Colleges and Universities
- Value for Ontarians
- Shows whether public college programs are producing employment outcomes, not just marketing claims.
- make100k use
- Program-to-$100K pages can compare salary destinations with official graduate employment signals.
- Join key
- college name, program/credential family, KPI year
- Limitations
- Employment outcomes do not prove that a specific graduate reached a Sunshine List role.
Quality gate
Program names, campuses, credentials, and KPI years must be matched before any school-level ranking is shown.
Ontario university graduate survey
Ready nextMinistry of Colleges and Universities
- Value for Ontarians
- Adds official outcomes for university routes such as teaching, engineering, accounting, nursing, and graduate degrees.
- make100k use
- Program pages can distinguish strong salary destinations from weak or unsupported school claims.
- Join key
- university, program/discipline, outcome year
- Limitations
- Survey results are graduate outcomes, not guaranteed earnings or public-sector placement.
Quality gate
Only compare programs after discipline labels, years, and sample caveats are preserved on the page.
Ontario public college programs: postsecondary field of study table
Ready nextMinistry of Colleges and Universities
- Value for Ontarians
- Gives make100k a program identity spine so school/program pages do not collapse different credentials together.
- make100k use
- Normalizes program names and fields before comparing outcomes or linking pathways to salary tracks.
- Join key
- college, program code, program title, credential type, CIP
- Limitations
- A program catalogue does not itself measure employment quality or salary destination.
Quality gate
Use as the identity layer only; ranking requires outcomes and salary-destination evidence.
Financial Information Return (FIR)
Ready nextMinistry of Municipal Affairs and Housing
- Value for Ontarians
- Connects municipal salary disclosure to municipal revenue, expenses, service areas, and local financial context.
- make100k use
- City pages can compare disclosed salary counts with municipal operating context and service categories.
- Join key
- municipality name, FIR code, fiscal year
- Limitations
- Municipal structures change, and FIR categories are not one-to-one with salary-disclosure employer names.
Quality gate
Municipality identity mapping and category definitions must be visible before ratios or comparisons ship.
Research and watchlist
These sources may matter, especially in health and education, but they need recency and coverage checks before they appear in salary analysis.
Career college key performance indicators
Research candidateMinistry of Colleges and Universities
- Value for Ontarians
- Can protect students from expensive weak-outcome programs if used with careful caveats.
- make100k use
- Potential private-career-college comparison layer for credential ROI and risk flags.
- Join key
- career college, program, campus, KPI year
- Limitations
- Private career college pages are high-stakes and need strict anti-advertorial separation.
Quality gate
Do not publish school-level claims until ranking independence, source quality, and disclosure rules are clear.
Public School Education Capital Information
Research candidateMinistry of Education
- Value for Ontarians
- Gives location and facility context for education-sector employers and communities.
- make100k use
- Potential city and school-board context: where education employers operate and how local salary density maps to facilities.
- Join key
- school board, school/building address, municipality
- Limitations
- Building data is not employee-level data and should not be presented as a payroll denominator.
Quality gate
Use only for location and facility context after geocoding checks and duplicate building review.
Self Reporting Initiative - Hospital Quarterly
WatchlistMinistry of Health
- Value for Ontarians
- Could help explain hospital compensation in the context of hospital budgets and service areas.
- make100k use
- Hospital employer pages may eventually add financial context after freshness and coverage review.
- Join key
- hospital name, reporting period
- Limitations
- The catalogue metadata is older than the salary graph's latest year, so it should not drive current claims.
Quality gate
Do not publish current comparisons until source freshness, coverage, and hospital identity matching are re-verified.
Wait Time Information System
WatchlistMinistry of Health
- Value for Ontarians
- May add service-access context for health-sector analysis if the data is refreshed and joinable.
- make100k use
- Potential health-sector research layer, kept separate from compensation claims unless coverage is current.
- Join key
- health organization, procedure/service category, reporting period
- Limitations
- Wait times are service-access metrics, not compensation outcomes. Coverage and recency must be explicit.
Quality gate
Require a current-source check and plain-language caveats before any health salary page references wait-time context.
What we will not do
We will not imply that payments, budgets, wait times, or facility data explain an individual salary.
We will not publish current claims from stale catalogue metadata without re-verifying the source.
We will not create indexable pages unless the data adds a useful Ontario-specific answer.
