We Work the Way You Do
Evolve Hyperbarics is the largest physician-supervised hyperbaric oxygen therapy network in Ontario, operating six regional clinics across the Greater Toronto Area and Northern Ontario. Each clinic is a regional node of the Evolve network, locally identified (Champagne Hyperbarics, Brampton Hyperbarics & Wound Care, York Hyperbarics, Sudbury Hyperbarics & Wound Care, Simcoe Hyperbarics, Durham Hyperbarics) and centrally supported. As an OHIP-approved provider, we deliver HBOT for 9 OHIP-covered conditions, alongside selected off-label care on a private-pay basis.
We work the way you do. Every patient referred to Evolve is assessed by a fellowship-trained hyperbaric physician. You receive a consultation note, a treatment summary, and a discharge letter. We make ourselves available to discuss complex cases by phone, and we will tell you honestly when HBOT is — and is not — likely to help your patient.
