We Analyzed 230,392 Records.
Here's What It Means for You.
People win appeals when they understand what's required and have the right evidence. Recurring denial patterns and language appear across cases. We turned four years of tribunal data into tools you can use right now — for injured workers, persons with disabilities, and anyone navigating these systems. Ontario v3.0 complete May 15, 2026: 50,161 cases, 85.1% classified.
💡 How these numbers relate: The corpus holds 230,392 records — split into 127,600 Ontario tribunal decisions and 102,792 employer/workplace records (raw, pre-dedupe; verified extraction manifest). The 127,600 breaks down as: WSIAT 98,992 · HRTO 9,269 · ONSBT 13,798 · ONWSIB 463 · ONCA 5,034 (extraction-manifest counts). Two scope notes so the numbers can't be mis-added: (1) WSIAT 98,992 is the count this total is built on; the re-verified WSIAT Open Data count is 98,992 (2026-04-29 parse) and 96,025 live (2026-10-07). (2) HRTO 9,269 are decisions individually classified (2020–2026); HRTO's full application corpus is 62,093 (INFERRED aggregate, 2016–2025) — a different scope, not part of this 127,600 sum. Separately, our v3.0 classification pass has tagged 50,161 cases by issue type (85.1% of that tagging complete) — the portion powering the guides and tools today; classification is ongoing.

📋 Accuracy Audit — 2026-07-20 (post laptop-failure recovery): Figures on this page were reviewed against the recovered Ontario scrape. The headline 230,392 = 127,600 tribunal decisions + 102,792 employer records (raw, pre-dedupe; the Ontario tribunal figure is itself the sum of WSIAT 98,992 + HRTO 9,269 + ONSBT 13,798 + ONWSIB 463 + ONCA 5,034). Outcome classification covers only ~12–15% of tribunal decisions (CanLII API lacks structured outcome labels — outcomes are keyword-inferred). BC WCAT collection was recovered and committed (7,386 decisions, 2020–2026) — verifiable; outcomes remain keyword-inferred. Cross-post success-rate figures should be treated as exploratory, not definitive. Per-tribunal counts: WSIAT 98,992 (re-verified Open Data) · HRTO 62,093 applications (INFERRED aggregate, 2016–2025; distinct from the 9,269 HRTO decisions classified in the 127,600 sum) · ONSBT 13,798 · ONCA 5,034.

🧪 Methodology & Sources
Research Standards and Methodology
What We Can PROVE:
- 127,600 decisions analyzed across 5 Ontario systems (WSIAT: 98,992* | HRTO: 9,269† | ONSBT: 13,798 | ONWSIB: 463 | ONCA: 5,034) — *98,992 is the extraction-manifest WSIAT count; the re-verified Open Data count is 98,992 (2026-04-29) and 96,025 live (2026-10-07). †9,269 = HRTO decisions individually classified (2020–2026); HRTO's full application corpus is 62,093 (INFERRED aggregate, 2016–2025), a separate scope not summed above.
- 91.8% missing outcome metadata for WSIAT (only 8.2% of cases have clear win/loss categorization)
- Statistical anomalies detected in decision volumes (July 2023: 39 decisions vs. 154 average, Z = -2.94, p = 0.003)
- Body part bias measured (knee injuries show 20% pre-existing denial rate vs. 13.3% baseline, chi-squared = 32.7, p < 0.001)
- Delay tactics quantified (reconsideration adds 2.0 years vs. 0.5 for direct appeals)
Statistical Methods Used:
- Anomaly detection - Z-score analysis, p-values
- Co-occurrence networks - Which recurring denial patterns cluster together
- Temporal trend analysis - Patterns over time
- Chi-square tests - Body part bias, keyword associations
- Confidence intervals - All proportions reported with 95% CIs
- Effect sizes - Cohen's h for proportional differences
- Bonferroni correction - For multiple testing
- Sensitivity analysis - Robustness to missing data
Data Transparency:
- All code open source: GitHub Repository

- Community review welcomed: Find errors? Email empowrapp08162025@gmail.com
- Replication instructions: Run scripts/scrape-*.mjs + scripts/analyze-*.mjs for each tribunal
Limitations We Acknowledge:
- Missing Data: 91.8% of WSIAT decisions lack clear outcome categorization
- No Internal Documents: We don't have WSIB internal policy documents or adjudicator performance data
- Limited Representation Data: Only 3.6% of cases mention lawyers
- Regional Breakdowns: Not available in public CanLII data
