Contact information for existing patients


If this is an emergency, please visit your nearest emergency room or contact your local Emergency Services at 9-1-1. 


Please note that we are not able to reliably satisfy urgent requests received by email, fax, or phone, particularly for medical issues or questions.

Instead, it may require up to several business days for us to respond. Should you need something addressed or answered more urgently, please book an urgent appointment with us or visit a walk-in clinic or urgent care center.

Administrative Questions

We try to supply answers to most administrative questions on our website. This helps us shift resources towards patient care, to respond to medical questions faster, and to develop better ways of operating.

Patient resources are available here and common questions have been copied below. We would appreciate you taking a moment to review these resources prior to contacting us.

How to contact us directly


We are currently piloting an online portal for patients of the following doctors:

  • Dr. Marco Lo

  • Dr. Nathalie Gans

  • Dr. Sabrina Chung

If (and only if) you are a patient of either of these physicians, please send your medically-related questions via the eVisit patient portal (for administrative inquiries, please continue to e-mail us a

If you do not have an account, please sign up on the portal page.  After a verification process, you will be able to send your concerns and questions. Learn more.


For patients of all other physicians (not listed above), our preference is that patients contact us via one (but not both) of the following email addresses

  1. For medically-related concerns and questions, please email instead of your physician directly. This helps minimize the risk that correspondence is missed and ensures questions are routed to the correct individual in a timely manner.

  2. For all administrative inquiries, please email us at

Kindly note it may require up to several business days for us to respond. As there is always a small risk of human error on our part, please don't hesitate to follow-up with us if you do not hear back within a week’s time.

Even if you have not completed our Authorization for Email Communication, if you email us without any indication that we should not respond by email, we will infer that we have your consent to at least reply to your email correspondence in the same manner (i.e. by email as well).


You are also, of course, always welcome to stop by in person. Our staff would be happy to assist as required.


We strongly prefer electronic written communication (e.g. emails), as we can respond in a more accurate, comprehensive, and timely manner. However, it is also an option to leave a voicemail with us at 647.479.8410, option 1.

Please note that if your inquiry can be handled online with our existing resources and systems, we will oftentimes ask you to do so.


Patients are asked to kindly refrain from faxing us directly. If you require your physician’s fax number please click here.

long term plan

We plan to eventually migrate to a secure web messaging portal to communicate with patients. Use of this portal will be mandatory as discussed here. Unfortunately, as no suitable option is currently commercially available, we make the above options available.
