The Diagnostic Sleep Clinic was founded in 1997 initially with a 3 bed facility.  The need for quality sleep assessments grew very quickly allowing for an expansion to 6 beds shortly after.


Dr. Erwin Feige provides expert diagnosis with over 20 years of direct sleep related medical experience.


The lab is staffed with 6 fully registered Polysomnographic Technologists and 5 additional that are registry eligible.  The DSC also serves as a training site for Respiratory Therapy students from Canadore College and Medical Students from the Northern Ontario School of Medicine.  The lab is accredited through the 'Independent Health Facilities' governing body.


Our Vision:
The Diagnostic Sleep Clinic was founded on the need to provide client focused service to the North. In all dealings with our clients, we endeavor to conduct ourselves with integrity and professionalism. We take your sleep needs very seriously and provide thorough patient follow ups to ensure you can enjoy a better quality of life.
