Coverage benchmark — Ashleigh Stewart (Global News) on CFB Wainwright against other outlets

Roger Wilco Imagery · 25 Oct 2026 · BENCH-002 · Coverage benchmark · Model-generated (LLM); see Method.

Correction (26 Oct): two statements about Global's desk were wrong — the 19 Oct timeline does not credit Stewart, and the first-night claims were not "walked back" (see BENCH-004). Stewart's grade is unaffected.

Bottom line

Ashleigh Stewart's Wainwright work for Global News rates A−. It is the most original reporting of any mainstream outlet. She was first to show the fire had been burning since about noon, and first to obtain the Range Standing Orders. She was also the most careful about what satellite data can and cannot prove.

  • Two scoops that set the agenda. The 20 Oct satellite analysis moved the story from "a sudden fire at 4 p.m." to "a fire burning for hours as a forecast front arrived". The standing-orders piece supplied the "plan early-morning shoots in August–October" rule that later coverage cited.
  • Disciplined with uncertainty. She stated that the detections "do not establish the size of the fire". She did not claim the noon fire was the one that killed the soldiers.
  • Main gaps. The 82 km/h gust is reported without its time; station records put it at 15:16. The standing-orders piece also repeats "broke out around 4 p.m." without reconciling it with her own noon finding.
  • A desk-level problem, not hers. Global's first-night report, from unnamed military sources, said a gas line or well was hit, causing an explosion. The claim fed misinformation that a Canadian Press fact-check later had to unwind.

Her Wainwright work

Two bylined analyses plus contributions to the desk's main stories; the analyses carry the weight.

Date Piece Role What it added
22 Oct Timing, weather under scrutiny in investigation Desk story (byline Alessia Simona Maratta) built on her analyses Standing-orders guidance put directly to Rutland; his reply: "that's a guideline"
20 Oct Wainwright fire burned for hours as volatile weather closed in Byline Landsat 8 hotspots 12:17 MDT (59 detections, ~1.6 km); VIIRS 14:49; ECCC warnings 14:15 and ~15:00; >10 °C temperature drop; CWFIS "extreme" vs internal memo "low"; implied 60–120 km/h spread tested with fire scientists
20 Oct Military safety rules urged early-morning training Byline Obtained the 139-page Range Standing Orders (2024); October flagged high-risk; firing before ~10:00; immediate grass-fire reporting; possible lapse in annual reissue after the April 2025 change of command
18 Oct Victims identified Additional reporting Shared desk file (the 19 Oct timeline, listed here earlier, does not credit Stewart — corrected 26 Oct)
19–21 Oct Posts on X, cited by Canadaland Records requests Asked ECCC for archived warning bulletins and XML; received boilerplate

Against other coverage

Most outlets relayed briefings. Stewart and Prime Rogue are the only two that produced evidence the briefings did not contain.

Outlet Main mode Original evidence Accuracy record Versus Stewart
Ashleigh Stewart / Global Data + documents Satellite detections, Range Standing Orders, fire-danger comparison, expert spread check No errors found in her bylined pieces —
Global News desk Breaking news "Multiple separate military sources" First-night seven-dead, explosion and gas-line claims; gas line removed without a note, the toll and explosion never corrected (see BENCH-004) Same outlet, weaker sourcing standard
Canadian Press Wire explainers, fact check Few; strong on corrections (pairs range, not section attack) No toll, explosion or gas errors of its own; small uncorrected errors (Canmore distance, "anti-grenade"); debunked the gas-well and fake-video claims Better at verification, less original
CBC Live blogs, interviews Access to the Chief of the Defence Staff Early toll of seven ("CBC News confirms"), superseded the same day with no editor's note found (BENCH-003) Better access, less analysis
CTV Briefing reports AGL range origin, from the 22 Oct briefing "Explosion" in its own headlines and live blog (17–18 Oct), attributed to Carney; never corrected. One correction notice (wind speed) Follows; no data
Globe and Mail News, health-system features DND's "about noon" ignition; "fire index low" message (with Global) No toll or cause errors found Graded B (provisional) in BENCH-005
Al Jazeera Synthesis None; cites Global's memo scoop Clean Derivative of Global
Canadaland Accountability commentary None; relies on Stewart's posts and one interview Fair Amplifies her access fight
Prime Rogue Modelling + records Station gust time, spread model, gas-line tests, regulator records, OCME jurisdiction Versioned, with logged corrections Builds on her Landsat find; goes further on weather and gas

Weaknesses and open checks

The weaknesses are omissions and one internal inconsistency, not errors of fact.

  • Gust without a time. The 82 km/h gust is reported for "that day". The station file puts it at 15:16 MDT, the single most important time in the event.
  • "4 p.m." left standing. The standing-orders piece says the fire "broke out around 4 p.m." on the same day her analysis showed fire from about noon.
  • Landsat image not shown. The FIRMS detections are cited, but not the noon image or a burn outline (~0.44 km² at 12:17).
  • No VIIRS pass record. The 14:49 detection is listed, but not the earlier passes that saw nothing. That record appears only in RWI SITREP 005.
  • Open check — Range 11. Prime Rogue attributes the identification of the AGL range as Range 11 to Global's standing-orders reporting. The retrieved text of that article does not name a range. This should be confirmed, since Prime Rogue's origin model depends on it.
  • Open check — first-night report. The byline and any correction notice on Global's 17 Oct gas-line story were not found.

Scorecard

Update (26 Oct): CTV's row revised after the full CTV review (BENCH-006): it reported an explosion in its own voice on 17–18 Oct, attributed one to Carney, and has not corrected it.

Update (26 Oct): Canadian Press row revised after the full CP review (BENCH-007).
