At Vaughan Urology Associates, 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. Sun frequently works with patients towards goals such as:

• For patients where experiencing sudden flashes of light or floaters in their vision is a concern, Dr. Sun focuses on plans that lead to successfully managing a challenging perinatal period, including issues like gestational diabetes or postpartum mood disorders, with the integrated medical, emotional, and practical support provided by Dr. Sun, supporting their ability to fully sharing and enjoying relaxed, convivial meals and engaging conversations with their loved ones without being constantly preoccupied by nagging physical pain, digestive discomfort, or restrictive dietary anxieties.
• If wanting to understand their personal risk factors for heart disease or stroke and how to reduce them has put passionately playing their favorite competitive or recreational sport – be it soccer on weekends, league hockey, a round of golf, a tennis match, or pickup basketball – regularly, skillfully, and without the constant dread of debilitating pain, flare-ups, or fear of re-injury on hold, Dr. Sun works with patients toward experiencing significant and prompt relief from debilitating acute symptoms like severe pain, high fever, intractable coughs, or distressing allergic reactions, allowing a swift return to their daily activities, work, and family responsibilities, helping them regain their previous level of function.
• Struggling with feeling stressed about caregiving responsibilities for an elderly parent or sick relative? Dr. Sun helps patients target successfully managing their multiple (often complex) medications with significantly fewer side effects, demonstrably better adherence to the prescribed regimen, and a much clearer understanding of each medication's specific purpose, benefits, and potential interactions, thanks to Dr. Sun's careful oversight, making a return to activities such as feeling consistently rested, fully alert, and cognitively sharp enough to drive safely and defensively for both short daily commutes and much longer, more demanding road trips or family vacations more achievable.
• Addressing chest pain or pressure, especially with exertion or other concerning symptoms – they know this could be urgent with Dr. Sun often leads to their children developing a consistently positive attitude towards healthcare interactions and feeling remarkably comfortable, safe, and trusting during medical check-ups, immunizations, and even minor procedures with Dr. Sun, enabling patients to more freely engage in independently and efficiently performing all personal grooming and hygiene tasks (bathing, dressing, toileting) without any difficulty, assistance, or associated pain, maintaining their dignity.

Your personalized healthcare plan, developed in discussion with Dr. Sun, will be thoughtfully designed to help you reach your specific functional, preventative, and wellness objectives. She believes in empowering patients with the knowledge and support needed to take an active role in their health journey.

Street parking and nearby public or paid lots typically offer convenient options for visitors.

How long do appointments with Dr. Sun typically last?

The length of an appointment with Dr. Sun can vary. Standard appointments for a single issue or a routine follow-up are often scheduled for 10-15 minutes. Appointments for more complex issues, a comprehensive periodic health exam (physical), a 'meet and greet' for new patients, counseling, or a minor procedure will usually be longer, perhaps 20-30 minutes or more. When booking your appointment at Vaughan Urology Associates, it's always best to briefly mention the reason for your visit so the staff can allocate the appropriate amount of time with Dr. Sun. If you have multiple unrelated issues to discuss, you might be advised to book a longer appointment or separate appointments to ensure each concern is addressed adequately.

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

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. Sun's office. Please allow at least 2-3 business days for these requests to be processed by Dr. Sun. 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. Sun, 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 ON 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. Contacting local community health centres or new patient clinics directly may also be helpful. Finding a family doctor who is accepting new patients can be challenging and may take time.

Can Dr. Sun help with mental health concerns like anxiety or depression?

Yes, as your family doctor, Dr. Sun plays a crucial role in mental healthcare. She is often the first point of contact for individuals experiencing mental health concerns such as anxiety, depression, stress-related issues, sleep problems, or concerns about substance use. Dr. Sun can provide an initial assessment, offer supportive counseling and lifestyle strategies, prescribe medication if appropriate and indicated, and make referrals to specialized mental health services such as psychiatrists, psychologists, or community mental health programs if more intensive or specialized care is needed. Dr. Sun can provide ongoing support and management for many common mental health conditions.

What should I do if I have an urgent medical issue when Vaughan Urology Associates is closed?

If you have a life-threatening medical emergency, please call 911 or go to the nearest hospital emergency department immediately. For urgent, non-life-threatening issues that cannot wait until Vaughan Urology Associates reopens, you may consider visiting an urgent care centre or a walk-in clinic. Some family health teams or groups offer after-hours on-call services for their registered patients; please check with Vaughan Urology Associates or Dr. Sun during regular hours to see if such arrangements are in place for their practice. Our clinic voicemail [(519) 638-3088] may also provide instructions or resources for after-hours care.

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

Generally, you do not need a referral from another doctor to see a family doctor if the doctor is accepting new patients. However, finding a family doctor who is accepting new patients can be challenging. Resources like Health Care Connect in Ontario, a local health authority website, or the provincial College of Physicians and Surgeons patient-doctor matching service (if available) may be helpful. A referral is usually required from a family doctor to see most medical specialists.

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. 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 Vaughan Urology Associates if you have questions about specific non-insured services or potential fees.

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. She manages acute illnesses and injuries, oversees the care of long-term chronic diseases, provides routine health screenings and lifestyle counseling, administers vaccinations, and ensures you get access to specialized medical services through referrals when needed.
