Peter Vadas MD, PhD

Allergist and Clinical Immunologist

Patients living in communities outside of southern Ontario may be seen via the Ontario Telemedicine Network (OTN).  Telemedicine referrals may be arranged by a physician or nurse practitioner.  Telemedicine referrals are open to both adults and children.  Referrals may be faxed to 416.864.3033  Dr. Vadas's staff will contact patients directly to arrange a Telemedicine appointment, after a faxed referral is received.

Please note that referral must include referring physician or NP letterhead and CPSO number and patient's email address

New patients are seen by referral only.  The practice is open to both adults and children.  Referrals should be faxed to 416.864.3033. 
The length of Telemedicine consultations are determined by the Ontario Telemedicine Network.
Initial consultations are limited to 30 minutes and follow-up appointments are limited to 15 minutes.


Initial Telemedicine consultations: 30 minutes

Follow-ups: 15 minutes


If you have to reschedule your appointment, we would appreciate as much advance notice as possible, to allow us to offer your time slot to another patient.  However, we require a minimum of 24 hours advance notice for cancelled or rescheduled appointments.  Patients who do not provide advance notice of cancellations will not be rescheduled. 


Test Results

Our office experiences a very high call volume.  As a result, Dr. Vadas does not provide test results, medical advice or prescription refills by phone, fax or email.  Patients may schedule an appointment with our office for these services or contact their family doctor.


Email Correspondence

Email correspondence is not secure and cannot guarantee confidentiality of health information.  For this reason, Dr. Vadas will not provide test results, medical advice or discuss medical conditions by email.
