The definitive recent piece. AHS data obtained by CBC via FOI. This one carries the direct causal testimony linking lost winter shelter space to frostbite.

Key figures (winter 2024-25 unless noted)

  • "Edmonton had 113 amputations performed with a diagnosis of frostbite last winter — more than five times the number recorded in fiscal 2019." (implies fiscal 2019 ≈ ~20–22)
  • "More than half of those procedures were performed on patients recorded as experiencing homelessness."
  • "Since 2021, a total of 188 frostbite amputations have been performed on patients experiencing homelessness in Edmonton. In Calgary during that time period, the total was 111."
  • Cold-injury ED visits: "The number of diagnoses of frostbite or excessive cold in Edmonton's emergency departments last winter jumped to 1,307 from 896 — the largest increase since at least 2011, as well as by far the most of any single year in that time period." More than half unhoused. (Calgary: 685 from 630.)
  • Calgary amputations fell for a third straight year (one fewer than prior winter); more than three-quarters of Calgary's were unhoused.
  • Dr. Scott MacLean (ER, Royal Alexandra): "We lost a lot of shelter space last year, especially during the winter in the daytime." "So many of our patients were coming in saying, 'Yeah, I was in shelter last night,' and they left in the morning and then they got frostbite."
  • Quinn Strikwerda (co-chair, Edmonton Coalition on Housing and Homelessness) on the majority-unhoused share: "That's a pretty devastating figure when you think about what a tiny percentage of the population that we're talking about here."

Winter shelter / extreme-weather gap

  • "When temperatures are forecast to drop below –20 C for a minimum of three days, the City of Edmonton activates additional services... including adding a fourth shelter shuttle bus and funding 50 overnight shelter spaces at Al Rashid Mosque."
  • Strikwerda: "It's the harshest benchmark that you'll find in Canada. If somebody's outside in –20 C weather and there's no extreme weather protocols, they can certainly get frostbite in one day, let alone in three days."
  • "Risk of frostbite begins at temperatures below 0 C, according to the Alberta government."
  • iloprost study finding: "35 per cent of the severe frostbite cases in Edmonton during the 2022-23 and 2023-24 winters occurred when the extreme weather emergency response was not activated."
  • City policy under review since late 2024, to be presented to council mid-2026.

Officials

  • Province (Jason Nixon, Assisted Living and Social Services) spun the rise as progress: "The increase in both frostbite diagnoses and amputations are a direct result of co-ordinated, concerted efforts to increase awareness and early intervention..."
  • Encampment dismantling "will continue this winter" in both Edmonton and Calgary, citing safety.
  • Bridge Healing transitional program (Francescutti): 80% reduction in ED return visits; buildings "constantly full."
