Ontario Breast Screening Program (O.B.S.P.)

The Ontario Breast Screening Program operates through Cancer Care Ontario to offer an accredited breast cancer screening service to women aged 50 and over. Breast screening includes a breast x-ray (mammogram) and the possibility of having a clinical breast examination as well as education on breast self-examination. This will be done by a trained nurse.

For appointments:
1-613-632-1111, ext. 71101 (answering machine on 24 / 24 )
Receptionist on duty Monday to Friday 8 a.m. to noon

The clinic is held every Tuesday and Thursday from 8 a.m. to 3:10 p.m. 
Women from Ontario aged 50 and over may call to make their own appointment or be referred by a doctor.

Practical Tips:
Before your visit

  • Do not wear any deodorant or powder when you come for your test so as not to have the results altered by the products.
  • You will be asked to remove your clothing down to the waist. You may want to bring your bathrobe if you do not wish to wear a hospital gown.
  • You will have to remove any jewelry worn around your neck. We suggest that you do not leave any valuables with your personal clothing.
After your visit
  • A Radiologist (a doctor who is trained to read mammograms) will look at your mammogram.
  • Within two weeks after your visit, you will receive a letter from us telling you the results of your breast screening.
  • With your approval, we will also send the results to your family doctor.
If your screening shows you need more tests, remember that:
  • About 1 out of 10 women who undergo breast screening need more tests.
  • If you need more tests, we will call you within the next seven (7) days following your exam and the letter outlining your results will state this as well.
  • 9 times out of 10, there is nothing to worry about.
  • Your doctor or the breast screening site will set up these tests for you. If necessary, your mammogram films may be sent to the doctor at the center where your tests will be done.
Coming back for breast screening
  • Until you reach the age of 75, you will get a letter from us reminding you when to come back for breast screening (every 1 to 2 years).
  • For women 75 and older, you will no longer get a recall letter. You will have to call for an appointment yourself (ext 359). You should discuss breast screening with your doctor.
Breast Health Studies
  • Sometimes, the Ontario Breast Screening Program asks women to be part of a study (or research) about breast health.
  • You will receive the same high quality breast screening and all your test results will remain confidential, whether you agree to be part of a study or not.
