St. Clare's is an adult acute care facility — if you are bringing a child requiring emergency care, the Janeway Children's Health and Rehabilitation Centre is the appropriate destination in St. John's.
Parking is limited and can fill quickly; consider arriving by taxi, rideshare, or Metrobus (Routes 2, 3, or 11) to avoid delays finding a space.
If you need to reach the ER by phone, be aware that getting through directly can be challenging — (709) 777-5000 is the main hospital number.
If visiting a patient in the ICU or a special care unit, call ahead to confirm visiting hours, as they differ from general ward schedules.
The emergency department is smaller than some larger urban ERs — if your condition is not immediately life-threatening, consider whether a walk-in clinic or virtual care option may be appropriate for your needs.
A Tim Hortons and cafeteria are available on-site if you are accompanying a patient for a longer wait — the cafeteria is open 7:00 AM to 6:00 PM.
