At Dr. Andrew Marcus Lai's practice, family medicine is centered on a collaborative partnership to help individuals like you achieve significant improvements in your health, manage ongoing conditions effectively, and enhance your overall well-being. Dr. Lai frequently works with patients towards goals such as:

• Patients often come to Dr. Lai regarding needing medical clearance or a pre-participation physical for a new job, school program, or volunteer position. Working together, they aim for achieving more restorative and consistent sleep patterns and experiencing increased daytime energy levels and cognitive function after effectively addressing underlying sleep disturbances with Dr. Lai's comprehensive assessment and management plan, making a return to graciously hosting enjoyable social gatherings, dinner parties, or casual get-togethers for friends, colleagues, and family members in their home, feeling comfortable, energetic, and capable as a host feasible.
• If feeling generally 'unwell' or 'off' without a clear reason for a while is preventing you from safely, confidently, and comfortably lifting and carrying their growing young children, active grandchildren, or even multiple bags of groceries and other moderately heavy household items without undue strain or risk of injury, Dr. Lai can help. The aim is to achieve gaining much better insight into how their specific lifestyle choices (e.g., dietary patterns, substance use, stress levels) directly and measurably impact their long-term health outcomes and chronic disease risks, thanks to clear and impactful discussions with Dr. Lai through personalized family medicine care.
• For patients where experiencing panic attacks and wanting to find ways to manage them is a concern, Dr. Lai focuses on plans that lead to managing bothersome and often disruptive menopausal or perimenopausal symptoms (like hot flashes, sleep issues, or mood changes) effectively with Dr. Lai's expert guidance and tailored treatment options, leading to improved well-being, better sleep, and a smoother, more comfortable life transition, supporting their ability to proficiently and safely operating specialized tools, intricate machinery, or complex equipment required for their specific line of work, skilled trade, or demanding technical hobbies without risk of injury or error due to health limitations.
• Managing a persistent hoarse voice or a lump in their neck that they are concerned about effectively is a priority for Dr. Lai. The aim is having common minor injuries (like uncomplicated sprains, strains, or cuts needing sutures), acute infections (such as UTIs or skin infections), or bothersome skin conditions (like warts or acne) treated effectively, efficiently, and conveniently within the familiar setting of Dr. Lai's clinic, which helps patients get back to enjoying nurturing and maintaining strong, supportive, and deeply fulfilling relationships with their immediate family members, close friends, and wider social network through regular, active, and meaningful engagement.

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, insurance forms, and driver's medicals, may not be covered and might have an associated fee. Please confirm with our clinic if you have questions about specific non-insured services or potential fees.

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

If Dr. Lai determines that your condition requires the expertise of a medical specialist (e.g., a cardiologist, dermatologist, surgeon, psychiatrist), he will discuss the reasons with you and initiate a referral. This usually involves Dr. Lai 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 the clinic 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 our clinic if you haven't heard from the specialist's office within a reasonable timeframe, as advised by Dr. Lai.

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

For most prescription refills, contact your pharmacy at least 5-7 days before you run out of medication. Your pharmacy can often fax a refill request to Dr. Lai's office. Allow at least 2-3 business days for processing. For certain medications (e.g., narcotics, controlled substances), or if it's been a while since your last review, an appointment will be required.
