Montreal 811 Health Line Guide for Visitors (Quebec): When to Call 811 vs 911, What to Prepare, and Simple Pharmacy First Steps

When to call 811 vs 911 (simple rule)

• Call 811 for non‑urgent health advice: you’re sick or unsure, but not in immediate danger.
• Call 911 for emergencies: severe symptoms, breathing trouble, chest pain, fainting, major injury, or immediate danger.

What to prepare before calling 811

• Your location (address + hotel name)
• Symptoms + when they started
• Medical conditions (asthma, diabetes, etc.)
• Medications you’ve taken
• Allergies

Tip: write a one‑sentence symptom summary in your notes app. It helps if you’re tired or translating.

Pharmacy first: the easiest option for many visitor problems

For colds, allergies, minor pain, stomach issues, and basics, pharmacies are often the fastest help. If you’re unsure what to take, 811 can also guide you on next steps.

Keep logistics simple if you feel unwell

• Use metro for the long hop and keep walks short.
• Carry water and keep your phone charged.
• If you’re alone, pick one “anchor” place and don’t overmove.

Direct booking helps when things go sideways

If you get sick or need to pivot, a predictable base makes everything easier: clear check‑in, calm space, and simple neighborhood access.
