Source dataset
The Government of Ontario publishes the Public Accounts of Ontario — Detailed Schedule of Payments annually. The dataset lists payments of $10,000 or more made by every ministry to every recipient in a given fiscal year. It is published under the Financial Administration Act, R.S.O. 1990, c. F.12.
The dataset is hosted at:
data.ontario.ca/dataset/public-accounts-detailed-schedule-of-payments
Each fiscal year has its own CSV/XLSX file. The fiscal year covers April 1 to March 31 (e.g., 2024-25 covers April 1, 2024 through March 31, 2025).
Recipients aggregated
Two corporate entities are aggregated:
AccertaClaim Servicorp Inc.
Federal corp № 3866378. Parent entity. Active federal lobbying registration filed through this corporation.
Accerta Services Inc.
Federal corp № 13426769. Incorporated October 14, 2021. Subsidiary of AccertaClaim Servicorp Inc. Operates AccessOAP.
Both entities use 777 Bay Street, Suite 2801, Toronto. Aggregating both is necessary because (a) AccessOAP-related payments to Accerta Services Inc. began in 2021 after the OAP contract was awarded, and (b) earlier payments are recorded against the parent entity. Aggregating both gives the complete picture of Ontario’s financial relationship with the Accerta corporate group.
Aggregation procedure
For each fiscal year file from 2017-18 through 2024-25 (eight files total):
- Filter recipient name for “AccertaClaim Servicorp Inc.” (variants: AccertaClaim, Accerta Claim, etc.).
- Filter recipient name for “Accerta Services Inc.” (variants: Accerta Services, Accerta Inc., etc.).
- Sum payments across all ministries (MCCSS, MOH, MGCS, MOL, etc.) within each fiscal year.
- Record per-entity totals and combined totals for each fiscal year.
- Sum across the eight fiscal years for the cumulative figure.
- Compute the year-over-year growth rate for Accerta Services Inc. specifically (2021-22 first non-zero year through 2024-25).
Year-by-year line items per ministry (MCCSS, MOH, MGCS, etc.) are available in the Ontario Public Accounts Detailed Schedule of Payments dataset and can be reproduced by filtering the dataset for AccertaClaim Servicorp Inc. and Accerta Services Inc. across fiscal years 2017-18 through 2024-25.
Headline figures
Combined Ontario payments
~$2.5B
AccertaClaim Servicorp Inc. + Accerta Services Inc., all ministries, 2017–2025.
Growth rate
~5,747%
Accerta Services Inc. payments, 2021–2025. Reflects the post-AccessOAP contract trajectory.
Both figures are approximations based on the published dataset. Per-year figures and per-ministry breakdowns are available to any reader who downloads the source dataset and applies the filters described in Step 3.
Interpretation notes
Inclusive of all ministries. The figure includes payments from any Ontario ministry, not only MCCSS. Accerta administers government-sponsored health benefit programs, and payments appear in multiple ministries depending on the program.
$10,000 disclosure threshold. The Public Accounts dataset reports payments of $10,000 or more. Smaller payments are not included. Aggregate figures could be marginally higher if all sub-threshold payments were included, but they would not change materially.
Pass-through versus retained revenue. Some payments to Accerta entities are administration fees retained by the company. Others are pass-through payments where the company processes claims on behalf of beneficiaries, and the dollar value flows on to clinicians, dental practices, etc. The Public Accounts dataset does not distinguish between these. The aggregate figure represents the total dollar value of payments made to Accerta entities; it does not represent profit, revenue, or retained income.
5,747% growth context. The growth rate is calculated from a low-base year (2021-22, when Accerta Services Inc. was newly incorporated) to a high-base year (2024-25, when AccessOAP administration was fully ramped). Such growth rates are common when a corporate entity is created specifically to administer a contract and then ramps to full operating scale. It is reported as a factual measure of the trajectory, not as a comparable performance metric.
Reproducibility statement
This methodology is reproducible. Anyone can download the Ontario Public Accounts — Detailed Schedule of Payments dataset for fiscal years 2017-18 through 2024-25 and apply the filters described above to verify the headline figures. The dataset is public, free, and published under an open data licence.
Corrections to this methodology are welcome via the right of reply. Any named party is invited to provide context.
