Our Services at OATC Ottawa

Methadone is an opioid agonist blocker and helps to reduce cravings and withdrawal symptoms when administered therapeutically by a medical professional. The dose is ingested, typically in liquid form, and is tapered off in accordance with cravings and withdrawal symptoms.

Suboxone contains Buprenorphine and Naloxone. Combined they block opioid receptors to prevent the effects of other opioids, with a built in ceiling effect preventing overdose or misuse.

"I've dealt with two clinics before this one & this blew my expectations out of the water. The hours are super convenient… the staff are kind and non-judgemental. The doctor I have is thorough in explaining things and very nice. Intake was very thorough which I liked & haven't experienced previously. I'll never recommended anywhere but here. If you're ready to make the changes needed, this is the best place to go."
Alexis K. from Oakville
"At the age of 40, I found myself divorced and addicted. With the help of doctors, nurses and staff at CATC, I got my life back."
Client from Ontario
"I am currently an appointed guardian of a patient who visits the OATC for the last month. This is my first experience regarding addiction treatment. The staff has made me and more importantly the patient feel very welcome, warm and not so clinical amd cold. Thank you for the job and the service you provide our community."
Client from Oakville
"Staff is amazing,very helpful, knowledgeable, and friendly, they give you the tools to succeed and you feel the support that you need in order to start living life again. I would recommend the OATC on Main and Tisdale to anyone looking for help with addictions."
Jon R. from Hamilton
"The team at OATC Keswick are amazing. They really do go above and beyond to ensure you get the best treatment. They treat you with the utmost respect and absolutely no judgment. The doctor is also amazing."

"I've been going here for a few years now. The people here are great and if it wasn't for this place I would be dead. This place really helps."
Steve S. from Brampton
"I’ve been dealing with Aylmer St. Pharmacy for a few years. Very excellent people and help… from all the workers.  Very friendly workers. Thanks for caring for me and all the customers."
Client from Peterborough, ON
"I am writing about my experience with Park Ave pharmacy. I recommend the pharmacy and give it 5 stars. I have dealt with lots of other pharmacies and have never felt comfortable. Whenever I had questions I felt like I was an inconvenience, but with this pharmacy, I've had all excellent experiences with all the staff. Jessica and Shawna have gone above and beyond to help me find answers and have always returned calls and emails quickly. I've had many health issues or concerns about methadone and I always got excellent help and advice. The staff treats their customers as if they are family and not once have I had a bad experience or felt uncomfortable speaking to anyone there. I don't just get my methadone, but all of my (and my family's) prescriptions here."
Client from Kitchener
"They say that “time heals all wounds” but what most fail to realize is that you need a spectacular group of special individuals, who are caring, friendly and nurturing, as well, to help and guide you, supporting your each and every step, supporting your recovery, at YOUR PACE……  I couldn’t have successfully gotten off the fentanyl, opioids, and painkillers, without the great loving care ALL OF YOU have provided to me, to give me the positive drive and push to get as clean as I’m becoming, making me feel more happiness and a noticeably higher level of self-worth and confidence."
Client from Windsor, ON
"I took a chance with the methadone program over a decade ago.  I can honestly say taking that step through the door has truly allowed me to get my life back.  It made me a responsible member of society.  It made me be able to have a great job and I got my kids back home where they belonged after many failed attempts to get sober.  I can honestly say joining the methadone program finally gave me my fresh start.  I will always be grateful they brought an OATC clinic to my small town of Pembroke."
Client from Pembroke, ON
