Why Use Rocket Doctor?


Skip The Waiting Room.

Our Rapid Access Addictions Medicine Clinic does not require any referrals or appointments, allowing you to see a doctor the exact same day, when you need it the most.


Manage Recovery Discreetly From The Comfort Of Home

Telehealth through Rocket Doctor is 100% discreet. Receive the care you need in the environment of your choice, via secure video platform. Your conversation with the doctor is totally confidential.

See A Doctor At A Time That’s Convenient For You

Walk in style visits allow for flexibility outside of regular doctor’s 9-5 office hours. We are open on evenings and weekends. Get in touch with our patient care team 24/7.

How it Works

Tell us about you

Click the 'See a doctor' button or give us a call to speak with a patient care coordinator who will assess your needs and send an intake form to be completed prior to your appointment. The intake form will ask questions about your substance use, lifestyle, and treatment goals to help the doctor identify how to best provide you care.

1 hour comprehensive assessment

Speak with a doctor or physician’s assistant for a custom treatment plan.

Follow-up visits

Attend as many follow-up visits as you need to get support with your treatment plan, address any question, and get help with symptoms of withdrawal if necessary.

Pay Nothing Out of Pocket

We bill OHIP directly. As a covered Ontario resident, you pay nothing.

We are working hard to build a culture and system that breaks down many of the traditional barriers to accessing care when it is needed the most. Virtual care is an excellent option for those who cannot, or simply don’t want to visit a walk-in clinic.


We offer medical addiction care, which includes counselling, referrals to community services, pharmacotherapy (prescriptions to help ease withdrawal and cravings), and more
