A walk-in clinic can treat far more than most people expect. In one same-day visit a physician can diagnose and treat infections, stitch a cut, drain an abscess, remove a splinter or tick, test a urine sample, swab for strep, treat shingles, start an inhaler and steroids for a chest flare-up, give injections, order bloodwork and X-rays by requisition, and send a prescription straight to your pharmacy. What a walk-in cannot do is admit you, image you on the spot, give IV treatment, or manage your long-term health. Rule of thumb: if the problem is new, specific, and one prescription or one procedure would resolve it, a walk-in can almost certainly handle it today.
Infections
| Condition | What happens in the visit |
|---|---|
| Sore throat | Examination, strep swab, antibiotics if indicated |
| Ear infection | Examination with an otoscope, drops or antibiotics |
| Sinus infection | Assessment, treatment, advice on what needs no antibiotic |
| Chest infection or bronchitis | Examination, X-ray requisition if needed, treatment |
| Urinary tract infection | Urine test, antibiotics |
| Pink eye and styes | Examination, drops or ointment |
| Skin infection or cellulitis | Assessment, oral antibiotics, instructions on when to return |
| Shingles | Diagnosis and antiviral treatment — time-sensitive, go early |
| Thrush and yeast infections | Examination and treatment |
| Dental abscess pain | Pain relief and antibiotics while you arrange a dentist |
| Possible pneumonia in a well-looking patient | Examination and same-day X-ray requisition |
Do not assume antibiotics are the answer. Many of these are viral, and a doctor declining antibiotics for a virus is giving you correct treatment, not withholding care.

Prescriptions and medication problems
| Situation | What a walk-in can do |
|---|---|
| You have run out of a regular medication | A short bridging supply to get you to your own doctor |
| A new side effect or reaction | Assessment and a change, with your doctor informed |
| Contraception started or renewed | Assessment and prescription |
| Emergency contraception | Prescribed, and much of it is available directly from a pharmacist |
| Antibiotic not working after several days | Reassessment and a change |
| You need a medication while travelling | Assessment, within reason |
| Long-term prescriptions for chronic conditions | Not here — these belong with the doctor managing the condition |
Tests a walk-in can order
A walk-in can order almost everything a family doctor can, by requisition:
- Full bloodwork — CBC, electrolytes, kidney and liver function, thyroid, sugar, cholesterol
- Urine tests and cultures
- Throat, wound and swab cultures
- Pregnancy testing
- X-rays
- Ultrasounds
- ECGs, at clinics with the equipment
- Sexually transmitted infection testing
The critical question before you leave: who gets the result, and how will I hear? A test ordered at a walk-in and never followed up is the most common failure in same-day care. Ask for the result to be copied to your family doctor, and ask what happens if it is abnormal.
Other things worth knowing you can get
- Travel health advice and some vaccines
- Flu shots and publicly funded immunisations
- Injections, including B12 and some allergy treatments
- Blood pressure assessment
- Pap tests, at clinics that offer them
- Sexual health assessment and STI treatment
- Mental health assessment, a first prescription, and a referral
- Minor ailment assessment where your pharmacist cannot help
- Sick notes and forms — usually for a fee, as these are not OHIP-covered
What a walk-in clinic cannot do
| Cannot | Where it belongs |
|---|---|
| Admit you to hospital | Emergency department |
| CT, MRI or same-hour imaging | Hospital, by urgent referral |
| IV fluids or IV antibiotics | Emergency or urgent care |
| Resuscitation or surgery | Emergency department |
| Manage diabetes, blood pressure or asthma long-term | Your family doctor |
| Cancer screening programs and recall | Your family doctor |
| Complex medication reviews | Your family doctor |
| Long-term mental health care | Your family doctor, and specialists |
| Track your referrals over months | Your family doctor |
| Hold your full medical history | Your family doctor |
This list is the argument for having both. A walk-in solves today. A family doctor holds the years.
How to get the most from one visit
- Bring one problem, or at most two. Ten minutes does not stretch.
- Bring your health card. Without it the visit may not be covered.
- Bring a written medication list with doses, including anything over the counter.
- Know your allergies.
- Know your pharmacy, so a prescription can be sent directly.
- Give your family doctor’s name, so the visit report reaches them.
- Say when it started and whether it is getting worse.
- Say what you are afraid it might be. Doctors cannot address an unspoken worry.
- Ask two questions before you leave: who gets my results, and what should bring me back?
FAQ
Will a walk-in doctor take me seriously?
Yes. Walk-in medicine is real medicine, and the physicians are fully licensed family physicians. What they lack is your history — which is why bringing your medication list and being clear about your symptoms matters so much.
Can a walk-in refer me to a specialist?
Often yes. The weak point is follow-up: a referral with no family doctor behind it may go untracked. Ask who will follow up, and tell your own doctor.
Can a walk-in clinic treat my child?
Yes, with one firm exception: a fever in a baby under three months goes straight to the emergency department.
Can I get a work or school note?
Usually yes, but it is not OHIP-covered, so expect a fee. Check first whether your employer actually requires one — many short absences do not need a note in Ontario.
Can a walk-in doctor do a physical or a full check-up?
No. A periodic health visit needs your full history and a longer appointment with your own doctor.
Will going to a walk-in affect my relationship with my family doctor?
Not your care. Under Ontario’s enrolment models a practice may be notified of outside visits, and frequent outside use can affect the practice’s funding — but you will never be refused care. Calling your own clinic first is still the better move.
What if the walk-in cannot treat my problem?
They will tell you where it belongs, and often arrange it — a referral, an urgent hospital assessment, or an appointment with your own doctor. Being redirected is a correct outcome, not a wasted visit.
Do I need to call ahead?
Not required, but it helps. Ask how busy the clinic is and whether same-day slots can be booked.
