Ontario Breast Screening Program

The Ontario Breast Screening Program (OBSP) is a province-wide effort aimed at:

  • Women aged 50 to 74 (Ontario residents only) who are at average risk for breast cancer. They can get a mammography every two years.
  • Women aged 30 to 69 (Ontario residents only) who are identified as being at high risk for breast cancer. They can get an annual mammography and breast magnetic resonance imaging (MRI) screening. The MRI is currently not available at HGH.

Regular examinations can help detect breast cancer early and provide women with more treatment options and better outcomes. For more information on this provincial program, visit Ontario Breast Screening Program.

How to access the program?

  • If you are aged 50 or over and have received a letter from the OBSP program, you may call us directly to book an appointment for a mammography. You do no need a referral from your family doctor.
  • Women identified as being at high risk must call The Ottawa Hospital Regional OBSP High Risk Centre at 613-728-6508.
