Canadian refineries
24 plants after cross-checking CFA, CER, NACEI, Statistics Canada, and operator pages — 17 CFA fuels/asphalt/lubricants plants at 1,928,000 b/d (1,928 kb/d), plus 6 bitumen upgraders (SCO capacity is a separate measure) and specialty sites such as Come By Chance. Map and lists use the Canada Energy Regulator’s three government regions.
Fuels capacity source: Canada’s Refining Sector map (May 2026). Coordinates: NACEI where matched, otherwise operator/public facility sources (24 of 24).

Regional structure
Two regional schemes appear in Canadian refining publications. The Canada Energy Regulator (government) aggregates refinery statistics into three regions. The Canadian Fuels Association (industry) maps plants into five regions. This site’s map, summary cards, and plant lists follow the CER government regions. Capacities follow the CFA May 2026 map.
CER — government data

Inventory cross-check
Cross-check of CFA May 2026 (17) against CER crude-refinery counts (16), NACEI Aug 2017 (21 Canada rows: 14 refinery + 5 upgrader + 2 asphalt), Statistics Canada 2024 (17 finished-product refineries including NL), CER 2022 upgrader snapshot, Cenovus/Braya operator pages, and EIA (no plant-level Canada table; NACEI is the shared North American inventory). Expanded directory lists 24 plants.
- Scotford Upgrader
Missing from CFA because: Bitumen upgrader producing SCO; CFA fuels map lists only the adjacent Scotford Refinery.
Added: Upgrader row, 320 kb/d SCO (CER 2022), NACEI-based coordinates with small map offset from the fuels refinery.
- Suncor Base Plant Upgraders
Missing from CFA because: Oil sands SCO upgrader, not a CFA fuels/asphalt plant.
Added: Upgrader row, 357 kb/d SCO (CER 2022), NACEI coordinates.
- Syncrude Mildred Lake Upgrader
Missing from CFA because: Oil sands SCO upgrader, not a CFA fuels/asphalt plant.
Added: Upgrader row, 350 kb/d SCO (CER 2022), NACEI coordinates.
- Horizon Upgrader
Missing from CFA because: Oil sands SCO upgrader, not a CFA fuels/asphalt plant.
Added: Upgrader row, 250 kb/d SCO (CER 2022) with industry cross-check ~270 kb/d, NACEI coordinates.
- Lloydminster Upgrader
Missing from CFA because: Previously excluded as “bitumen upgrader, not on CFA map.” Cenovus discloses it in Canadian Refining alongside the asphalt refinery.
Added: Upgrader row, 81.5 kb/d nameplate (Cenovus), NACEI SK-side coordinates. Distinct from Lloydminster Asphalt Refinery (AB).
- Long Lake Upgrader
Missing from CFA because: Idle upgrader (not CFA fuels). CER 2022 excluded from active totals.
Added: Idle upgrader row, 58 kb/d SCO capacity when operating, OSM coordinates, status full_shutdown / idle.
- Come By Chance Refinery (Braya)
Missing from CFA because: Converted from crude refining to renewable diesel; not on CFA May 2026 crude map. CER crude count excludes it.
Added: Renewable-fuels specialty row, 18 kb/d renewable diesel (Braya), NACEI coordinates (former NARL).
Not added separately — NewGrade Upgrader (Regina): Integrated into the Co-op Refinery Complex; FCL and CER treat it as part of the Regina complex. Noted on ca-sk-regina-fcl rather than double-counted.
Incident data sources checked
Ontario SAC and AER Field Surveillance lists are ingested into the downtime check. Quebec has no comparable province-wide open spill feed.
- Environmental Occurrences and Spills (open CSV/XLSX)
Ontario Ministry of the Environment, Conservation and Parks
Ingested
Annual Spills Action Centre open CSV. Matched to Ontario plants by municipality and petroleum-refining sector.
- Field Surveillance Incident Inspection List
Alberta Energy Regulator
Ingested
Field Surveillance Incident Inspection List (release + complaint CSV). Matched by licensee name and Alberta Township System boxes around published AB plants.
- Pipeline Incident Data

Works
Open CSV for pipeline/processing-plant incidents. Pipeline-focused, not refinery flaring. Not yet ingested.
- Provincial environmental occurrence open data

Not found
No province-wide machine-readable spill/flare extract comparable to Ontario SAC. Contaminated-site (GTC), municipal wastewater, and Montreal city reports are not equivalent downtime feeds.
Capacity cross-checks over 5%
Stored capacities follow the CFA May 2026 map. Alternates that differ by more than 5% are flagged on the plant page; the CFA figure is unchanged.
- Montreal Refinery
CFA 137,000 b/d vs 157,000 b/d (14.6%)
Operator site differs by more than 5% from the CFA May 2026 map figure used here.
- Sarnia Refinery
CFA 85,000 b/d vs 92,000 b/d (8.2%)
Operator site differs by more than 5% from the CFA May 2026 map figure used here.
- Edmonton Refinery
CFA 146,000 b/d vs 159,000 b/d (8.9%)
Operator site differs by more than 5% from the CFA May 2026 map figure used here.
- Horizon Upgrader
CFA 250,000 b/d vs 270,000 b/d (8%)
Industry technical page cites about 270 kb/d SCO; CNRL regulatory nameplate often cited near 271 kb/d.
