ProHealth Medical Clinic

***UPDATE REGARDING COVID-19 (updated June 29, 2020)***

We ask that all patients coming to the office wear a facemask.

We do our best to prioritize patients’ health and safety. We have been screening all patients with the following questions during appointment bookings via phone and registration at the front desk. Thank you for your cooperation! We will be offering virtual/telephone consults (**please see details below) during this pandemic to minimize the need for patients to come into the office.  

1) Do you have a fever (Temperature > 38C)?

2) Do you have a cough/congestion/runny nose?

3) Have you travelled outside of Canada the past 30 days?

4) Have you been in contact with a confirmed or probable case of COVID-19?

If you answered yes to any of these questions, it is imperative that you inform our office PRIOR to coming to our office.

*Saturday walk-in clinic will be closed until further notice*

At this time, please minimize coming to the doctor’s office for non-essential services. Please call our office if you’re not sure if you should come in or not. Our staff will try to help you determine a course of action. Please avoid bringing visitors who are not patients to the clinic unless necessary. Our clinic also offers a pre-existing non-OHIP private telephone medicine program (ProHealth Plus) run by our registered nurse who has access to your medical chart for telephone medical advice if you would like to sign up for this (between 9am-5pm, Mondays to Fridays).

**COVID-19 is placing stress on Canada’s public health system. Our clinic has been offering virtual care to make sure that we can continue to care for our patients safely and effectively. This means that we will be using video and audio technologies for some patient visits rather than asking all patients to come into our office. Some of these technologies are provided by the province. Others have been provided by vendors such as Google, or Apple to help make discussions with your care provider as easy as possible during these difficult times. Some health concerns can be addressed with virtual care alone, but in some cases your doctor may ask you to visit a hospital or other health- care facility if necessary, for a physical examination.

We do our best to make sure that any information you give to us during virtual care visits is private and secure, but no video or audio tools are ever completely secure. There is an increased security risk that your health information may be intercepted or disclosed to third parties when using video or audio communications tools. To help us keep your information safe and secure, you can:

  • Understand that this method of communication is not secure in the same way as a private appointment in an exam room.
  • Use a private computer/device (i.e., not an employer’s or third party’s computer/device) and a secure internet connection. For example, using a personal computer or tablet is more secure than using someone else’s computer, and your access to the Internet on your home network will generally be more secure than an open guest Wi-Fi connection.

You should also understand that virtual care is not a substitute for in-person communication or clinical examinations, where appropriate, or for going to an Emergency Department when needed (including for any urgent care that may be required).

If you are concerned about using video or audio tools for virtual care, please let our front staff know and we can try to accommodate you or make other arrangements. However, please note that visiting a health care provider in person comes with a higher risk of coming into contact with COVID-19 and the possibility of spreading the virus.

By providing your information, you agree to let us collect, use, or disclose your personal health information through video or audio communications (while following applicable privacy laws) to provide you with care. In particular, the following means of electronic communication may be used: audio or videoconferencing (including Ontario Telemedicine Network (OTN).

Welcome to ProHealth Medical Clinic.  We are committed to delivering top quality healthcare.

Currently, we are staffed by family physicians (2 of whom are affiliated with the University of Toronto), an allergist, a gastroenterologist, a headache specialist (neurologist), an oncologist, a dietician and a registered nurse.  Dr. Hsu is also affiliated with North York General Hospital.  Our clinic is involved in a research study based out of the University Health Network.

For patients registered with our office, we also offer an innovative telephone medicine program: PROHEALTH PLUS 最新电话医疗计划 (in Chinese 中文 and English). By enrolling in this program, you will have access to our office’s registered nurse for personalized telephone medical advice, Monday to Fridays from 9am to 5pm via a separate private telephone line.  She will have access to your medical records and have the back-up of a family physician from our office if required. This nursing telephone service saves you from taking time off work just to come in to review a simple test result and can help guide you through specific medical questions. This non-insured service is not covered by OHIP and will require an enrolment fee. For more information, please speak with our office staff or your doctor.

對於在我們診所註冊的客人,我們還提供新的電話醫學計劃PROHEALTH PLUS。(中文版本介紹英文版本介紹)。通過註冊該電話醫療計劃,您可以在周一至週五的上午9點至下午5點之間撥通專綫電話與我們辦公室的註冊護士談話,以獲取專門的電話醫療建議。她將可以透過你的病歷來解答你的問題,如有需要時,護士會和你的家庭醫生進一步解答你的疑難問題。這個電話醫療計劃會為你節省時間,例如,無需在上班時間專門請假來看一個化驗測試結果;而是可以通過熱綫就可以幫您解決特定的醫療問題。 該電話醫療計劃不在安省健康卡的服務範圍,所以需要支付註冊費。有關更多的信息,請與我們的辦公室工作人員或您的醫生查詢。
