Tips Before You Go

• 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.

What to Bring

• Government-issued photo ID (e.g., driver's licence or passport)
• Provincial health card (NL MCP card)
• List of current medications, dosages, and allergies
• Any relevant medical records, imaging, or test results
• Provincial drug plan card or private insurance information
• Emergency contact name and phone number
• Phone charger or portable battery pack for long waits
• Comfortable clothing and a light jacket, as waiting areas can be cool
