Nurse-patient ratios: Canada vs Australia.
Australia's Queensland and Victoria mandate minimum nurse-patient ratios. Canada (with the partial exception of British Columbia's 2024 agreement) does not. The 2021 Lancet paper by McHugh, Aiken et al. — the gold standard dose-response evidence — found that each additional patient assigned raises mortality risk by 7%. The figures below frame what's at stake.
Side by side
| Dimension | Canada (national) | Australia (Queensland) |
|---|---|---|
| Nurses per 1,000 population (OECD 2025) | 10.3 per 1,000 | 12+ per 1,000 |
| Province- or state-mandated ratios | BC since April 2024 only; no national mandate | Queensland + Victoria mandate; legislated minimums |
| Mortality effect per extra patient (Lancet 2021) | Same biology — Canadian replications consistent | +7% mortality per additional patient |
| Workforce response post-mandate | Pending — too early to measure BC trend | Lower mortality, fewer readmissions, shorter LOS |

Frequently asked
- Does an extra patient really raise mortality risk?
- Yes — peer-reviewed dose-response. McHugh, Aiken et al., The Lancet (2021): 27 hospitals, ~17,000 nurses, 400,000+ patient records. Each additional patient assigned raised the chance a patient dies by 7%, raised readmission risk by 3%, and lengthened length of stay.
- Why doesn't Canada mandate ratios nationally?
- Health is a provincial jurisdiction in Canada. British Columbia became the first province to mandate ratios in April 2024 (BCNU agreement). Other provinces have not legislated minimums — Ontario's ONA arbitration in September 2025 explicitly excluded staffing ratios.
- What's Canada's nurses-per-1000 ranking internationally?
- Canada has 10.3 nurses per 1,000 people (OECD 2025), below Australia, Germany, the United States, and far below Norway / Finland / Switzerland (>18 per 1,000).
