Frequently asked questions

How long is the ER wait at Stevenson Memorial Hospital right now?
As of the latest update, about 2h 31m to be seen at Stevenson Memorial Hospital. The figure refreshes roughly every 10 minutes and is the hospital's own live estimate, not a guarantee: an emergency room always treats the sickest patients first, so your own wait can differ.
What does the wait time actually measure?
Usually the estimated time to be seen by a physician, but Canada has no common definition. Quebec publishes stretcher occupancy, New Brunswick length of stay, and others an estimate of the wait to be seen, so we keep each province in its own units and never blend them into one misleading number.
How accurate are these ER wait times?
They are the live estimates each hospital publishes, refreshed about every 10 minutes; we stamp every reading with the moment the hospital said it was current and flag a feed that goes stale. They are estimates, not guarantees, an emergency room always sees the sickest patients first, so your own wait can differ. We also backtest our forecasts against what hospitals post next; see the accuracy page.
Should I go to the ER, or somewhere else?
For anything life-threatening, call 911 or go to the nearest emergency room now, never wait for a shorter posted time. For a non-urgent problem, calling 811 (free 24/7 health advice), a walk-in clinic, or a pharmacist is often faster. When in doubt, get checked.
