Urgent care is a healthcare service focused on providing immediate, non-life-threatening medical attention. Urgent care centers treat conditions such as sprains, cuts, burns, and common illnesses and offer a range of services, including diagnostic and preventive care like immunizations and physicals. With an estimated 15,000 clinics in the U.S., urgent care centers operate beyond traditional primary care office hours, offering a convenient and lower cost alternative to emergency rooms for urgent but minor health issues.

What is a walk-in clinic?

A walk-in clinic is a type of healthcare facility that provides medical care to patients without the need for an appointment. These clinics cover a range of services such as urgent care, occupational medicine, and primary care with walk-in availability. They cater to non-emergent health issues, offering a convenient option for accessible medical attention. Walk-in clinics vary from free services provided by government, charity, or foundation-operated facilities to private clinics with affordable rates, serving as a practical alternative for minor illnesses and injuries outside of traditional doctor's offices and emergency rooms.

Do urgent care centers in Ontario take appointments?

Historically, urgent care centers were strictly an on-demand, walk-in healthcare service. More recently, as consumer behaviors and expectations have evolved, many urgent care clinics have begun offering book ahead visits, allowing consumers to select a same-day or next-day time that works best for their schedule. Use Solv to find a Ontario urgent care center that offers advanced bookings (or appointments) and book online.

Are Ontario urgent care centers open after hours?

Yes. Most primary care doctor offices are open during routine work hours, Monday thru Friday, 9:00 am to 5:00 pm. Conversely, most of the urgent care centers in Ontario are available after hours, on weekends, and many holidays. Typical urgent care hours are 8:00 am to 8:00 pm daily, although location-specific hours may vary.

How much will an urgent care visit in Ontario cost?

The cost of a visit to an urgent care in Ontario varies, with cash prices for the base visit generally ranging from $100 to $175. Additional treatments, such as lab tests, X-rays, or immunizations, can increase costs, typically between $50-150 each. If you're using insurance, expect a co-pay between $20 and $50, depending on your plan and whether the clinic is in-network. Prices differ based on location, so it's best to check directly with the urgent care center and your insurance provider for accurate cost estimates.

My husband has pneumonia, so as soon as I started coughing, I made an appointment at the new Marque Urgent Care on Alicia Parkway. It was so easy to start an account and get in quickly. The place is beautiful and the staff was so friendly. Check-in was fast. The PA was so knowledgeable about my asthma and gave me meds to keep it from becoming worse. I feel so much better after only 2 days.They contacted me by phone and text to make sure I was better. Love this place!

Pain from Sciatica had become unbearable. I wasn't able to schedule an appointment with my doctor, but I went online to Carbon Health's website and had no trouble booking an appointment. I was seen on time, the facility was clean & comfortable, the check-in process was hassle free, and the young lady at the front desk was polite and professional. Dr. Upton was a tremendous help to me. In addition to being able to prescribe the right medication for my condition, she advised me regarding lifestyle changes that might be beneficial. Above all - SHE LISTENED to me! I would certainly recommend this location to my friends and neighbors.
