• For patients where their child has a foreign object stuck in their nose or ear (and it seems minor enough for the clinic) is a concern, Dr. Nicholson focuses on plans that lead to feeling deeply understood, consistently validated, and never dismissed by Dr. Nicholson when discussing sensitive, personal, or emotionally difficult health topics or life circumstances, supporting their ability to feeling profoundly secure, deeply supported, and well-understood in having a trusted, accessible, and long-term medical advisor and health partner in Dr. Nicholson for any and all health questions, new symptoms, or emerging concerns that arise throughout their lives.

Dr. Nicholson guides patients so they can again enjoy consistently maintaining a regular, enjoyable, and suitably challenging active lifestyle through various forms of exercise, preferred team or individual sports, invigorating outdoor adventures, or mindful movement practices like yoga or tai chi.
• A frequent goal for patients seeing Dr. Nicholson about experiencing sudden hearing loss or ringing in their ears (tinnitus) is to achieve experiencing a marked and sustained improvement in their overall sense of well-being, daily energy levels, vitality, and a noticeable, positive enhancement in their day-to-day quality of life and functional capacity.

How can I find a family doctor (Family Doctor) in ON who is accepting new patients?

Finding a family doctor in Ontario who is accepting new patients can be challenging. The College of Physicians and Surgeons of Ontario often has a "Find a Doctor" tool or list on their website. In Ontario, you can register with Health Care Connect. You can also ask friends, family, or colleagues for recommendations, or contact local community health centres or new patient clinics directly. It may take time to find a suitable doctor.

What exactly is a family doctor (Family Doctor) and what is their role?

A family doctor (Ontario) is a physician who has completed post-graduate training in family medicine. They are skilled in providing continuous and comprehensive medical care, health maintenance, and preventive services to patients of all ages. This includes diagnosing and treating a vast array of illnesses, managing complex long-term health conditions, offering health education and counseling on lifestyle choices, and acting as your advocate and guide within the broader healthcare system.

Is seeing a family doctor (Family Doctor) covered by Ontario Health Insurance Plan (OHIP) in ON?

Medically necessary visits to a family doctor are typically covered by the Ontario Health Insurance Plan (OHIP) for eligible residents with a valid provincial health card. However, some services, such as cosmetic procedures, most travel medicine consultations, sick notes for work/school, insurance forms, and driver's medicals, may not be covered and might have an associated fee. Please confirm with Sunnybrook Health Sciences Centre if you have questions about specific non-insured services or potential fees.

What should I expect during my first 'meet and greet' or new patient intake appointment with Dr. Nicholson?

When you first meet Dr. Nicholson as a new patient, expect to spend time discussing your complete health profile. She will likely ask about your past medical history, significant family illnesses, all current medications (including vitamins and supplements), allergies, lifestyle factors like diet and exercise, and any specific health concerns or goals you have. This comprehensive intake helps Dr. Nicholson understand your overall health status and begin to formulate a long-term care plan. It's also an excellent time to ask any questions you may have about her approach to medicine or clinic procedures.

Do I need a referral to see a family doctor (Family Doctor) in ON?

Generally, you do not need a referral to see a family doctor in Ontario if the doctor is accepting new patients. However, finding a family doctor who is accepting new patients can be challenging. Provincial resources like Health Care Connect in Ontario, or the College of Physicians and Surgeons of Ontario website, may be helpful. A referral is usually required from a family doctor to see most medical specialists.

What happens if Dr. Nicholson determines I need to see a medical specialist?

If Dr. Nicholson determines that your condition requires the expertise of a medical specialist (e.g., a cardiologist, dermatologist, surgeon, psychiatrist), she will discuss the reasons with you and initiate a referral. This usually involves Dr. Nicholson sending a formal referral letter along with your relevant medical information to the specialist's office. Wait times for specialist appointments can vary significantly depending on the specialty and the urgency of your condition. The staff at Sunnybrook Health Sciences Centre will typically inform you once the referral has been sent, and in most cases, the specialist's office will contact you directly to schedule an appointment. Please follow up with Sunnybrook Health Sciences Centre if you haven't heard from the specialist's office within a reasonable timeframe, as advised by Dr. Nicholson.
