Tips Before You Go

• The ER is located at 840 McConnell Ave — not 14 York St. Verify your destination before leaving home.
• Triage is based on medical severity, not arrival order — a nurse will assess you promptly, but wait times depend on how urgent your condition is compared to others.
• For non-emergency concerns, consider calling 811 (Ontario's Telehealth line) before visiting the ER to determine if your situation requires immediate care.
• The ER averages about 140 visits per day, so evenings and weekends may see higher volumes — arrive early in the day when possible for less urgent issues.
• If you are seeking mental health or addiction support, Cornwall Community Hospital has dedicated CAMHS programs and crisis resources available through the ER.

What to Bring

• Ontario Health Card (OHIP card)
• Government-issued photo ID
• List of current medications, dosages, and allergies
• Any relevant medical records, test results, or referral letters
• Name and contact number of your family doctor or specialist
• Phone charger or portable battery pack for long waits
