Tribunal Data Visualizations

Exploring 230,392 records from Ontario’s workplace injury and human rights systems

For ONWSIB-specific visuals and summaries, use the reconciled 2020-2026 archive of 463 internal review decisions. Public outcome visibility remains limited: 95.7% unresolved, so any apparent ONWSIB win-rate figure should be read as a classified-only subset snapshot, not a system-wide success rate.
