• Clinic Closed

    A message from Dr. Reimer: Please note that The Reimer Clinic is now closed. We do not plan to reopen. It has been an honour and a privilege for our entire team to serve thousands of people over the years at our facilities, first on Frederick Street in Kitchener and then on Old Innes Road in Ottawa. Lives have been saved, cancers have been prevented and many thousands have been reassured.

    Unfortunately, OHIP funding for colonoscopy has been repeatedly reduced over the last two decades. Costs rise each year. The pressure to be faster and cheaper grows each year. It is time to move on. The ultimate cause of our closure is a massive failure of the public system to put the patient's best interest before its own financial interest. Sub-par funding is not unique to colonoscopy. Other recent examples are the closing of a large nearby family medicine clinic, which is analyzed in a CBC news pieceOntario Eye Care, Virtual Care in New Brunswick, and so plainly visible, funding for our long-term care homes.

    As I enter the next phase of my career, I see a great need to help our seniors. They deserve more than the current health system can offer. Long before COVID came, we launched Freiheit Care Inc. to provide premium quality home care and to help provide respectable wages to hard-working, career-oriented caregivers. The need for unrushed, professional and consistent home care is greater than ever. I believe I can be part of the solution to this massive challenge.

    If you require colonoscopy services, there are several options in town. As I transition my focus, I have reduced my medical practice to two days a week at Provis Endoscopy. I can be reached through their offices. There remain two other private clinics in the National Capital Region. Most public hospitals offer this care, although generally with longer waiting lists. Beyond that, patients willing to self-pay may be able to find quick access to care in Montreal.



Welcome to The Reimer Clinic

We exist "So That No One Dies of Colon Cancer".


What we Do

We exist to save lives.

We can avoid colon cancer, and if necessary, survive it! All it takes is proper screening.

Our staff and physicians care for people having colonoscopies and their families every day. We have extensive medical experience and we extend a personal, reassuring and respectful environment in which we can provide you with screening services in a maximum of comfort.

We provide short waiting times in a health system where waiting lists for colonoscopy can be months or years.  We believe in world-class patient service and have the highest standards of quality medical care that can be offered with the government funding that we receive. Of course, if you have OHIP insurance, your care is "free".
