Currently, all 10 provinces and the Yukon have organized breast screening programs. The Northwest Territories is in the process of implementing such a program. Breast cancer screening in all organized programs includes a two view screening mammogram. For the purposes of the Canadian Breast Cancer Screening Database, the target population is defined as asymptomatic women between the ages of 50 and 69 with no prior diagnosis of breast cancer.
Some programs also screen women outside the target age groups.
