For decades, many people knew cervical screening simply as “the Pap test.” Ontario changed its organized screening program in March 2025. The province now uses a human papillomavirus test as the primary cervical screening test because it identifies the infection responsible for almost all cervical cancers more accurately.
The appointment still involves collecting a small sample from the cervix, but the laboratory process and routine interval have changed. Most eligible people with a negative result now screen every five years rather than every three.
This guide explains who should be screened, what happens during the appointment, how HPV results are interpreted and why screening remains important after vaccination or menopause.
Why Ontario moved to HPV testing
Almost all cervical cancers are caused by persistent infection with high-risk types of HPV. HPV is extremely common and usually causes no symptoms. In most people, the immune system clears the infection without treatment. A smaller number of infections persist and can gradually cause abnormal cervical cells.
The Pap test looked directly for abnormal cells. Primary HPV screening looks first for the high-risk virus that can cause those changes. When indicated, the laboratory can then examine the collected cells. Detecting risk earlier allows the program to provide a longer interval after a reassuring negative result while directing closer follow-up to people who need it.
Screening is prevention, not a cancer diagnosis
Cervical screening is offered to people who do not have symptoms. It estimates risk and looks for changes before cancer develops. An HPV-positive result does not mean a person has cancer. It means a high-risk HPV type was detected and the program will recommend the appropriate next step.
Likewise, a negative result is reassuring but does not mean a person can ignore new symptoms for five years. Unusual bleeding, pain or discharge is assessed diagnostically and should not wait for the next routine screen.
Who is eligible in Ontario?
Ontario’s current program generally recommends cervical screening when all of the following apply:
- you have an Ontario health insurance number;
- you are at least 25 years old;
- you have a cervix;
- you have ever had sexual contact with another person;
- you do not have symptoms requiring diagnostic assessment; and
- you are due according to program guidance.
The wording “sexual contact” is intentionally broader than penetrative intercourse. HPV can pass through intimate skin-to-skin contact.
Screening recommendations are based on anatomy and history, not gender identity or sexual orientation. Transgender men and non-binary people with a cervix may need screening. People in same-sex relationships and those with only one lifetime partner can still acquire HPV.
Why routine screening begins at age 25
HPV infections are common in younger people and often clear on their own. Screening too early can detect temporary infections and cell changes that would never cause harm, leading to anxiety and unnecessary procedures.
Ontario therefore does not recommend routine cervical screening under age 25, even after sexual contact. Symptoms are different: unusual bleeding, discharge, pelvic pain or a visible concern should be medically assessed at any appropriate age.
How often is the test needed?
Most eligible people with a negative HPV result are advised to screen again in five years. The interval is longer than the former Pap schedule because a negative primary HPV test is strongly reassuring.
Not everyone follows the routine interval. People who are immunocompromised, including some people living with HIV or taking immune-suppressing medicine, may need screening every three years. Previous abnormal results, cervical treatment or colposcopy can also create a different follow-up plan.
Use the recommendation attached to your actual result. Do not calculate your next date solely from a friend’s experience or an old Pap schedule.
Should screening continue after HPV vaccination?
Yes. HPV vaccination greatly reduces the risk from the cancer-associated types it covers, but it does not cover every high-risk type. Some people were exposed before vaccination or did not complete the recommended series.
Vaccination and screening do different jobs. Vaccination prevents many future infections; screening identifies current risk and related cervical changes. Together, they provide stronger prevention.
What about menopause or no recent sexual activity?
Screening may still be needed after menopause, in a long-term relationship or after many years without sexual contact. HPV can remain unnoticed for a long time, and relationship status does not erase prior exposure.
Most people can stop screening from age 65 to 69 if they meet the program’s exit criteria and do not have a history requiring continued follow-up. A clinician can review previous results rather than stopping automatically on a birthday.
Screening after hysterectomy
The answer depends on whether the cervix was removed and why surgery occurred. A total hysterectomy usually removes the uterus and cervix, while a subtotal procedure may leave the cervix in place. Previous high-grade cell changes or cervical cancer can also affect follow-up.
Do not guess from the word “hysterectomy.” Ask a clinician to review the operative history and pathology when possible.
Preparing for the appointment
Bring the date and result of your last cervical screen and any colposcopy or treatment records. Tell the clinic if you may be pregnant, have active bleeding, use vaginal medications or need accessibility accommodations.
You do not need to shave or change normal external hygiene. Avoid douching. If you are menstruating, ask the clinic whether the appointment should proceed; light bleeding may be manageable, while heavier bleeding can interfere with the sample.
If pelvic examinations are painful or distressing, mention this while booking or before undressing. Preparation can include a longer appointment, a smaller speculum, a support person, different positioning or another visit dedicated to discussion.
What happens during sample collection
You undress from the waist down in private and receive a drape. The clinician explains the examination and positioning. A speculum is gently inserted into the vagina so the cervix can be seen. A small soft brush collects cells from the cervix, and the sample is sent to the laboratory.
The collection usually lasts only a few minutes. Pressure and brief cramping can occur, but severe pain is not something you must silently tolerate. Tell the clinician what you feel.
Consent is ongoing. You can ask to pause, change position or stop at any point. A respectful clinician should explain before touching and avoid rushing you.
Making the examination more comfortable
Several strategies may help:
- empty your bladder before the examination;
- ask the clinician to explain each step or, if you prefer, keep conversation minimal;
- request the smallest appropriate speculum;
- agree on a clear signal to pause;
- use slow breathing and consciously relax the jaw and pelvic muscles;
- ask about another position if lying on your back is uncomfortable;
- bring a support person if clinic policy allows; and
- discuss vaginal dryness or previous pain in advance.
Trauma-informed care gives you control and choices. It does not require disclosing details you do not want to share.
What the results may mean
A negative high-risk HPV result generally returns you to routine screening in five years, unless individual factors change the interval.
When high-risk HPV is detected, the laboratory and program consider the viral type and any cell changes. Some results lead directly to colposcopy, an examination of the cervix under magnification. Others lead to repeat HPV testing after a specified interval.
An abnormal or positive result is not the same as cancer. It identifies a group that benefits from closer observation or assessment. Following the recommendation is the most important action.
Understanding colposcopy
Colposcopy uses a magnifying instrument to examine the cervix more closely. The instrument remains outside the body, while a speculum allows the clinician to see the cervix. Small biopsies may be taken from areas that appear abnormal.
Referral can sound frightening, but most people referred do not have invasive cancer. The purpose is to identify which changes need monitoring or treatment before they progress.
Bring questions and confirm who will communicate pathology results. Do not miss follow-up because symptoms are absent; cervical cell changes often cause none.
Symptoms that need assessment outside routine screening
Contact a healthcare professional for:
- bleeding after sex;
- bleeding between periods;
- any vaginal bleeding after menopause;
- persistent unusual watery, bloody or foul discharge;
- ongoing pelvic pain or pain during sex; or
- another new gynecologic concern.
These symptoms often have causes other than cancer, but they deserve diagnostic evaluation. A routine screening result cannot rule out every gynecologic condition.
Heavy bleeding with dizziness, fainting, severe pain or pregnancy possibility can require urgent or emergency care.
Cervical screening is not STI screening
The HPV cervical test is designed for cancer prevention. It does not provide a complete STI screen and does not test for chlamydia, gonorrhea, HIV, syphilis or herpes.
If there has been a possible exposure or symptoms such as discharge, burning or sores, discuss separate sexual-health testing. Samples may sometimes be collected during the same visit, but they are different tests with different purposes.
What if you are overdue?
Many people delay screening because of access, caregiving demands, fear, previous pain or a history of trauma. The helpful response is not shame. Contact a clinic and explain what would make the appointment manageable.
If records are missing, provide as much history as you know. The clinician can help determine whether screening is due and what pathway applies.
Protecting cervical health beyond screening
HPV vaccination can prevent infections responsible for many cancers and genital warts. Avoiding tobacco also matters because smoking is associated with persistence and progression of cervical cell changes. Barrier protection reduces—but does not eliminate—HPV transmission.
The most effective strategy is layered: vaccination when appropriate, regular screening, timely follow-up and assessment of symptoms.
The bottom line
Ontario’s cervical screening program now begins with a high-risk HPV test. Most eligible people start at age 25 and, after a negative result, screen every five years. Vaccinated and postmenopausal people may still need screening, while symptoms should be assessed rather than waiting for a routine appointment.
