Here is something most Ontarians do not know, and it is stated plainly on the province’s own website: “Requisitions for insured services are valid at any Ontario location providing the same service. Patients have the choice of where to receive their services and are not limited to the location that is printed on the requisition form.”

rn

That sentence is worth reading twice, and it is the reason a walk-in X-ray Richmond Hill and Aurora patients can reach in fifteen minutes is a genuine option rather than a compromise. When your doctor in Richmond Hill or Aurora hands you a requisition with a hospital’s name pre-printed at the top, that is where their office usually sends people. It is not where you are obliged to go. If another licensed facility performs the same OHIP-insured exam and can see you sooner, you can take the form there instead. No permission needed, and no new requisition.

Quick Facts: Walk-In Imaging Near Richmond Hill and Aurora

King City Diagnostic Imaging offers walk-in X-ray six days a week with no appointment, and books ultrasound, mammography, bone density, FibroScan, vascular ultrasound and cardiology within one to two business days. We are 10 to 15 minutes from Richmond Hill and a short drive from Aurora, Newmarket, Vaughan and Nobleton, with free parking outside. All exams are covered by OHIP when ordered by a physician or nurse practitioner. Your requisition is valid here regardless of which clinic is printed on it.

Walk-in X-ray runs six days a week, including Saturdays. Bring your requisition and health card.

If you have been searching for a walk-in X-ray Richmond Hill or Aurora residents can reach quickly, this is it. X-ray at King City Diagnostic Imaging is walk-in, Monday to Friday from 9:00 a.m. to 5:00 p.m. and Saturday from 9:00 a.m. to 4:00 p.m. We are closed on statutory holidays.

rn

Bring your requisition and your health card. That is it. No phone call, no booking, no waitlist. Most people are in and out in well under half an hour, and the imaging itself takes five to ten minutes.

rn

This matters most for the exams that are urgent in a practical sense even when they are not urgent in a medical sense. A suspected fracture after a fall on the ice. A chest X-ray your doctor wants before clearing you for surgery. A pre-employment or immigration chest film with a deadline attached. A child’s wrist after a Saturday morning soccer game. None of these should require waiting until Thursday.

rn

The Saturday hours are deliberate. A great deal of imaging demand in York Region comes from people who work full-time and cannot take a weekday afternoon off for a ten-minute exam. Full details are on our X-ray service page.

Walk-in works for X-ray because X-ray is fast and does not require a dedicated technologist for an extended block of time. Ultrasound, mammography, bone density, FibroScan, vascular studies and cardiology all need a booked slot, but “booked” does not have to mean “eventually.”

rn

We routinely have same-day appointments available, and most bookings land within one to two business days. Appointment hours are Monday to Friday from 8:30 a.m. to 5:30 p.m. and Saturday from 8:30 a.m. to 5:00 p.m.

Ontario publishes wait time data for CT and MRI, and the numbers show how much variation exists between facilities in the same region. As of June 2026, non-urgent CT waits at Mackenzie Health’s Richmond Hill and Cortellucci Vaughan sites averaged roughly 39 and 64 days respectively, while Southlake in Newmarket averaged around 114 days. Same province, same funding model, same priority category, and roughly three times the wait depending on where the form was sent.

rn

Worth knowing: Ontario does not publish wait time data for ultrasound, X-ray or mammography at all. The province tracks adult and paediatric CT and MRI only. So when someone quotes you a provincial average wait for an ultrasound, there is no authoritative source behind that figure.

rn

What we can tell you is our own booking window, which is one to two business days for most exams and zero for X-ray.

rn

The underlying pressure is real and not anyone’s fault locally. Nationally, CT volumes grew about 90 per cent between 2006 and 2023 and MRI volumes grew about 117 per cent, while the Canadian Association of Radiologists identifies staffing, meaning technologists and radiologists, as the primary constraint on throughput. Community clinics exist in part to take pressure off hospital departments absorbing that growth alongside emergency and inpatient demand. We cover this in more depth in our guide to imaging wait times and OHIP coverage in Ontario.

We are at Unit 1, Building H, 1700 King Road, King City, just west of Keele, with surface parking directly outside. No parking garage, no ticket machine, and no ten-minute walk from a lot to a department on the third floor of a hospital.

rn

Approximate drive times: Richmond Hill 10 to 15 minutes, Aurora 12 to 18 minutes, Oak Ridges around 10 minutes, Maple and Vaughan 12 to 18 minutes, Newmarket around 20 minutes, Nobleton around 10 minutes, Kleinburg around 15 minutes, Schomberg around 12 minutes, and Bolton around 20 minutes.

rn

For most of Richmond Hill and Aurora, King Road is a straightforward run west off Bathurst or Yonge, or east from Highway 400 at the King Road exit. GO Transit’s Barrie line stops at King City station, about a five-minute drive away.

rn

If you are weighing a 15-minute drive against a three-week wait, the drive usually wins.

Everything on this list is covered by OHIP when ordered by a physician or nurse practitioner.

rn

X-ray, walk-in, covering chest, spine, extremities, joints and abdomen, including pre-operative and pre-employment films.

rn

Ultrasound, including general abdominal, pelvic, obstetric, musculoskeletal and small parts, with same-day urgent scans when clinically needed.

rn

Vascular ultrasound, including carotid Doppler, leg venous studies for suspected DVT, arterial and peripheral vascular assessment, and aortic screening.

rn

Mammography, including screening mammograms through the Ontario Breast Screening Program. If you are 40 to 74 with no breast symptoms, you do not need a requisition at all.

rn

Bone mineral density (BMD/DEXA) for osteoporosis screening and monitoring.

rn

FibroScan (liver elastography), a non-invasive assessment of liver stiffness and fat with no needles and no radiation, which is genuinely hard to find in community imaging outside downtown Toronto.

rn

Cardiology, including echocardiography and cardiac diagnostics.

Ontario is unusually direct about this, and every patient should know it. The province states that it is illegal for licensed centres to charge you for services insured by OHIP, to charge you for preferential access to insured services, or to charge you facility costs such as overhead or operating fees relating to insured services.

rn

Community diagnostic clinics in Ontario are publicly funded facilities licensed under the Integrated Community Health Services Centres Act, 2023, which replaced the Independent Health Facilities Act in September 2023. There are more than 900 licensed centres in the province, the majority providing diagnostic imaging. They are inspected against standards set by Accreditation Canada, with results posted publicly, and they fall under the jurisdiction of Ontario’s Patient Ombudsman.

rn

The practical translation is that if a clinic performs your OHIP-covered X-ray or ultrasound, you pay nothing. Not a facility fee, not an administrative fee, and not a priority booking fee.

rn

There are genuinely uninsured services, such as third-party forms requested by an employer or insurer, imaging requested for legal proceedings, and some record-copying fees. Those must be optional, disclosed in advance, and you must always be given the choice to receive only the OHIP-insured portion. General information is available on the Government of Ontario’s website.

For almost everything, yes. Diagnostic imaging in Ontario requires an order from a physician or nurse practitioner. This is not clinic policy but how the insured service is defined, and it exists so that exams are matched to a clinical question rather than requested speculatively.

rn

Since July 2023, nurse practitioners can order X-ray, ultrasound, CT and MRI for any body region as OHIP-insured services. If your NP wrote the requisition, it is valid.

rn

The exception is screening mammography. If you are 40 to 74, live in Ontario and have no breast symptoms, you can self-refer to the Ontario Breast Screening Program with nothing but your health card, a rule in place since October 2024.

rn

If you do not have a family doctor, walk-in clinics and Ontario Health Teams can issue requisitions. We cannot order imaging for you ourselves, but we can tell you exactly what to ask for.

Do I need an appointment for an X-ray? No. X-ray is walk-in, Monday to Friday 9 to 5 and Saturday 9 to 4. Bring your requisition and health card.

rn

Can I get an X-ray without a requisition? No. An order from a physician or nurse practitioner is required for diagnostic X-ray in Ontario.

rn

My requisition says a different clinic. Can I still come here? Yes. Ontario’s own guidance is explicit that requisitions for insured services are valid at any Ontario location providing the same service. You do not need a new form.

rn

Is there a walk-in X-ray open Saturday near Richmond Hill? Yes. We are open Saturdays from 9:00 a.m. to 4:00 p.m., about 10 to 15 minutes from Richmond Hill.

rn

How long is the wait to book an ultrasound? Typically one to two business days, with same-day slots often available.

rn

Can I get an X-ray and an ultrasound at the same clinic? Yes. We do both on site, along with mammography, bone density, FibroScan, vascular ultrasound and cardiology, and where scheduling allows we will combine exams into one visit.

rn

Will I be charged anything? Not for OHIP-insured exams ordered by a physician or nurse practitioner. Charging patients for insured services is illegal in Ontario.

rn

How do I get my results? The radiologist’s report goes to the doctor or nurse practitioner who ordered the exam. Discuss results with them, as they have your full clinical picture.

rn

Is there parking? Yes, free surface parking directly outside the building.
