ER Compass for developers & data teams

Live and historical Canadian emergency-room data: one normalized API across every province, validated for accuracy, with forecasts and a clean commercial licence.

Why ER Compass data

• Breadth, normalized. Every reporting province and territory, one consistent schema, the cross-feed name-matching already solved.
• Accuracy you can cite. Posted waits checked against CIHI's measured figures, with a per-ER reliability signal, not raw scraped numbers.
• The full archive. Deep historical series (the public site exposes only a 14-day window) for backtesting, capacity planning, and research.
• Forecasts. Per-hospital next-12-hour and on-arrival wait forecasts with confidence bands.
• Reliable & supported. A stable schema, an uptime commitment, change notices, and a human to email.
• Clean licence. A commercial-use licence fit for embedding and redistribution (the free public tier is CC-BY, for non-commercial use).
