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 (e.g., cosmetic procedures, most travel medicine consultations, sick notes for work/school, insurance forms, driver's medicals) may not be covered and might have an associated fee. Please confirm with Southlake Regional Health Centre if you have questions about specific non-insured services or potential fees.

How do I get a prescription refilled by Dr. Lajeunesse?

For most prescription refills, please contact your pharmacy first, at least 5-7 days before you run out of medication. Your pharmacy can often fax a refill request directly to Dr. Lajeunesse's office. Please allow at least 2-3 business days for these requests to be processed. For certain medications (e.g., narcotics, controlled substances, or medications requiring close monitoring), or if it has been a while since your last review with Dr. Lajeunesse, an appointment will be required to assess your condition and ensure the medication is still appropriate and at the correct dose. It is always best to request refills proactively.

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

The College of Physicians and Surgeons of Ontario often has a 'Find a Doctor' tool or list. 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. Finding a family doctor who is accepting new patients can be challenging and may take time.

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

Your family doctor (Ontario) is your primary healthcare provider, expertly trained to care for a wide spectrum of health issues, from newborns to seniors. They manage acute illnesses and injuries, oversee the care of long-term chronic diseases, provide routine health screenings and lifestyle counseling, administer vaccinations, and ensure you get access to specialized medical services through referrals when needed. The continuity of care they provide, understanding your health history and individual needs, is fundamental to effective family medicine.

What is 'continuity of care' and why is it important with a family doctor like Dr. Lajeunesse?

Continuity of care means having an ongoing relationship with your family doctor, Dr. Lajeunesse, and her team over time. It's important because it allows Dr. Lajeunesse to get to know you, your health history, your values, and your family context comprehensively. This deep understanding helps Dr. Lajeunesse make more informed diagnoses, tailor treatments to your specific needs, coordinate your care more effectively with specialists, and build a trusting therapeutic relationship. Studies show that good continuity of care with a family doctor is linked to better health outcomes, higher patient satisfaction, and more appropriate use of healthcare resources.

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 if they are accepting new patients. However, finding a family doctor who is accepting new patients can be challenging. Provincial resources like Health Care Connect in Ontario may be helpful. A referral  is usually required from a family doctor to see most medical specialists.

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

Your first appointment with Dr. Lajeunesse will involve a review of your medical history (past illnesses, surgeries, allergies, immunizations, family history), discussion of current health concerns, medications, and lifestyle habits. A basic physical examination may be performed. This is also a chance to ask questions about her practice style and clinic policies (appointments, refills, communication). The goal is to gather comprehensive information for your ongoing care.
