Canadian pipeline incident safety intelligence (annual)
Operator-by-year pipeline safety intelligence for Canada from the Canada Energy Regulator's comprehensive incident file (2008 to present, quarterly vintage): 63 raw company names entity-resolved to canonical pipeline systems with parent companies, a documented 0-100 per-incident severity score aggregated to operator-year means with deterministic ranks, and CER cause categories consolidated into cause groups with fractional attribution. Counts cover significant incidents, ruptures, fatalities, injuries, evacuations, and released volumes. Quarterly.

| Column | Type | Description |
|---|---|---|
| year | integer | Incident year (2008 to present). Join key. |
| operator_canonical | string | Canonical pipeline-system operator after entity resolution of the 63 raw CER company-name variants. Primary key with year. |
| parent_company | string | Best-effort ultimate parent (September 2026). 'Not mapped' means ownership was not verified, not independence. |
| operator_aliases | string | Raw CER Company names resolved to this operator, '; '-joined. |
| country_code | string | ISO 3166-1 alpha-3 country code (constant CAN). |
| provinces | string | Provinces with incidents this year, '; '-joined. |
| n_provinces | integer | Count of provinces with incidents. |
| incident_count | integer | CER incidents for this operator-year. |
| incident_rank | integer | Within-year rank by incident_count (1 = most incidents). |
| significant_count | integer | Incidents flagged Significant by the CER. |
| significant_share | float | significant_count / incident_count, 0-1. (unit: ratio) |
| rupture_count | integer | Incidents involving a pipeline rupture. |
| fatalities | integer | Deaths recorded across incidents. |
| injuries | integer | Individuals injured across incidents. |
| evacuations | integer | People evacuated across incidents. |
| volume_released_m3 | float | Sum of reported released volumes. Blank upstream volumes are excluded (see n_volume_reported), never imputed. (unit: m3) |
| n_volume_reported | integer | Incidents with a numeric released volume this operator-year. |
| fire_explosion_count | integer | Incidents whose type includes Fire or Explosion. |
| release_count | integer | Incidents whose type includes Release of Substance. |
| n_open | integer | Incidents not yet marked Closed by the CER. |
| severity_mean | float | Mean of the documented 0-100 per-incident severity scores (+15 Significant, +25 rupture, +30 fatality, +15 injury, +10 fire/explosion, +10 release, +min(15, 5*log10(1+m3))). |
| severity_max | float | Maximum per-incident severity this operator-year. |
| severity_rank | integer | Within-year rank by severity_mean (1 = highest mean severity; operator_canonical asc tie-break). |
| top_what_group | string | Dominant consolidated 'what happened' cause group by fractional attribution. |
| top_what_share | float | Fractional share of the top what-group, 0-1. (unit: ratio) |
| top_why_group | string | Dominant consolidated 'why it happened' cause group by fractional attribution. |
| top_why_share | float | Fractional share of the top why-group, 0-1. (unit: ratio) |
| substances | string | Distinct substances involved, '; '-joined. |
| substance_top | string | Most frequent substance this operator-year. |
| pipeline_types | string | Distinct CER pipeline/facility types, '; '-joined. |
| vintage | string | Fetch date (YYYY-MM-DD) of the CER file behind this snapshot. |
| row_hash | string | Deterministic 16-hex hash of vintage + operator + year + rounded numerics; identical input hashes identically. |
