🇨🇦 ECCC Precipitation Network Audit

Ontario & Quebec — 2594 Stations Analyzed

V2 — ECCC 5-Category Classification per Minister Dabrusin's Response

📋 Methodology (Updated per ECCC Guidance, January 2026)

This audit implements the classification framework from Minister Julie Dabrusin's official response. Data sources updated to ECCC-recommended MSC Datamart and Collaboration Server (obsolete FTP removed). Stations classified into 5 categories per ECCC guidance. Effective failure rate excludes decommissioned stations.

Policy Implications

🌾 Agricultural Insurance

29.1% of active stations failing means actuarial models for AgriInsurance lack the precipitation data they need. This directly affects crop insurance pricing for Ontario and Quebec farmers.

🌡️ Paris Agreement (Art. 13)

Canada committed to transparent, accurate climate monitoring. With 145 active stations failing to transmit data, the precipitation record has permanent gaps that undermine international reporting obligations.

🔬 Scientific Integrity

Climate research requires continuous long-term records. Stations classified as ACTIVE_TRANSMISSION_ISSUE create gaps that distort trend analysis and regime change detection.
