The Ontario Cervical Screening Program (OCSP) is an organized, population based cervical cancer screening program. The Current OCSP cervical screening recommendations state that women should begin cervical screening at age 21 if they are or have ever been sexually active. With the implementation of human papillomavirus testing, Ontario Health (Cancer Care Ontario) will be changing the age of initiation to age 25 and updating the screening recommendations. In the meantime, Ontario Health (Cancer Care Ontario) encourages primary care providers to wait until people turn 25 before screening with the Pap test.
