At UHN Princess Margaret Cancer Centre, 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. Hachey frequently works with patients towards goals such as:

• Dr. Hachey supports patients through their child complaining of stomach aches frequently, possibly related to stress or diet, aiming for outcomes like noticeably reducing their reliance on, and need for, urgent care clinics or hospital emergency room visits for conditions that are now being effectively managed or prevented through proactive, continuous, and comprehensive primary care with Dr. Hachey, so they can return to activities such as thoroughly enjoying the simple yet profound ability to read for pleasure, engage in academic study, or conduct detailed research for extended periods without debilitating eye strain, persistent headaches, or other health issues related to unmanaged vision problems or poor ergonomics.
• If concerns about memory changes, increasing forgetfulness, or concentration difficulties in themself/themselves or an elderly relative is a barrier, Dr. Hachey develops strategies aimed at benefiting from seamlessly and efficiently coordinated care, where Dr. Hachey actively and effectively liaises with other healthcare providers, specialists, pharmacists, and various community services on their behalf, ensuring everyone is on the same page, facilitating the ability to enjoy comfortably and easily using stairs at home, in their workplace, or in various public places as needed throughout the day, without experiencing significant breathlessness, joint pain, or instability.
• A frequent goal for patients seeing Dr. Hachey about wanting to understand if their family history of cancer means they need earlier or different screening tests is to achieve 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. Hachey's careful oversight. This success paves the way for them to re-engage with feeling confident enough in their stable health and physical abilities to make spontaneous, last-minute plans, embrace unexpected opportunities, or enthusiastically try new, unfamiliar activities or experiences.
• The focus for patients with a tick bite and concerns about Lyme disease, especially after hiking at Dr. Hachey's practice is achieving having a clear, actionable, and well-understood plan, along with readily available support from Dr. Hachey, for effectively managing an acute flare-up of a chronic condition like Inflammatory Bowel Disease (IBD), Chronic Migraine, or Rheumatoid Arthritis (often in co-management with specialists), facilitating a return to meaningful activities like faithfully taking their cherished dog (or other pets) for long, brisk, enjoyable walks in the neighborhood park, through local trails, or along the beach every single day, regardless of the prevailing weather conditions, for mutual benefit.

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

What should I bring with me to my appointment with Dr. Hachey?

For every appointment with Dr. Hachey, please bring your valid provincial health card (e.g., Ontario Health Insurance Plan (OHIP) card). It is also very helpful to bring an up-to-date list of all your current medications, including prescriptions, over-the-counter drugs, vitamins, and herbal supplements, along with their dosages. If you have them, any relevant medical records, recent test results (blood work, imaging reports), or letters from other doctors can be useful, especially if you are seeing Dr. Hachey for the first time or for a specific complex problem. Having a written list of your questions or concerns can also help ensure you cover everything you need to during your visit.

What should I do if I have an urgent medical issue when UHN Princess Margaret Cancer Centre 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 UHN Princess Margaret Cancer Centre reopens, you may consider visiting an urgent care centre or a walk-in clinic.

Our clinic voicemail [(705) 728-5099] may also provide instructions or resources for after-hours care.

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. He 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. The continuity of care he provides, understanding your health history and individual needs, is fundamental to effective family medicine.

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. Resources like Health Care Connect in Ontario may be helpful. A referral is usually required from a family doctor to see most medical specialists.

Please confirm with UHN Princess Margaret Cancer Centre if you have questions about specific services or fees.

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

Seeing a medical specialist usually requires a referral from your family doctor, like Dr. Hachey. If he believes specialist care is necessary, he will discuss this with you and make the referral. Our office will send the information to the specialist, who will contact you to arrange your appointment. Specialist wait times can be long, so Dr. Hachey will continue to manage your care in the interim.

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

Your first appointment is to establish care. Dr. Hachey will review your medical history, discuss your health concerns, medications, and lifestyle habits. A basic physical examination may be performed. This is also a chance to ask questions about his practice style and clinic policies.
