During the application process, it is a routine step for many applicants to identify signs of active or previous tuberculosis (TB) infection. The process is typically rather quick, safe, and straightforward.
This guide explains why chest X-rays are required for Canadian immigration, who needs one, possible exemptions, what happens after the scan, and how abnormal findings are handled by IRCC.
Why Is a Chest X-Ray Required for Canadian Immigration?
Canada requires immigration medical exams to protect public health and prevent the spread of communicable diseases. One of the primary conditions screened during the medical exam is tuberculosis.
The chest X-ray helps physicians identify the following:
- Active pulmonary tuberculosis
- Previous TB infection or scarring
- Other serious lung abnormalities that may require follow-up
Public health deemed TB a concern because it can spread through the air when an infected person coughs or sneezes. Detecting active TB before entry into Canada helps reduce transmission and ensures applicants receive appropriate treatment if necessary.
In many cases, a chest X-ray is requested as a routine precautionary screening measure and does not mean that IRCC suspects an applicant has tuberculosis.
Who Needs a Chest X-Ray?
Most immigration applicants aged 11 and older are required to complete a chest X-ray as part of their immigration medical exam.
This typically includes applicants for:
- Permanent residence
- Work permits
- Study permits
- Refugee or asylum applications
- Certain visitor visa applications involving extended stays
A panel physician will determine whether the X-ray is required based on your age, application type, medical history, and IRCC guidelines.
Exemptions for Children Under 11
Most children under the age of 11 are exempt from routine chest X-rays because the risk of active TB is lower in young children, but this is not always the case.
Children may still be required to undergo an X-ray if they have symptoms consistent with tuberculosis, have been in close contact with someone diagnosed with TB, or the panel physician identifies a potential medical concern during the medical exam. If this were to arise, additional tests might be required to ensure they do not have an active infection.
Pregnancy and Chest X-Rays
Applicants are often worried that radiation exposure during immigration medical exams may cause some problems for their unborn child. In most cases, the chest X-ray can be rescheduled until after delivery or completed safely with protected shielding.
Shielding is typically used to minimize radiation exposure to the abdomen and fetus. The radiation level from a standard chest X-ray is considered to be very low. If the procedure is postponed, it can delay the processing of the immigration application because IRCC requires the results to finalize medical clearance.

What Is Medical Surveillance?
If the applicant has a history of treated tuberculosis or inactive TB- related abnormalities, IRCC may approve the application with a condition called medical surveillance. This means the applicant must report to public health authorities after arriving in Canada for a follow-up appointment to ensure monitoring can be carried out. This is not a refusal. It is a routine public health measure designed to ensure that individuals with prior TB history remain medically stable.
What Happens if the Chest X-Ray Is Abnormal?
It’s important to mention that an abnormal chest X-ray does not automatically mean your application will be refused.
In many cases, the findings may relate to:
- Old healed infections
- Lung scarring
- Non-TB respiratory conditions
- Technical imaging irregularities
However, if the physician identifies possible signs of active or previous tuberculosis, additional testing will be required, which may include:
Sputum Testing
Applicants may be asked to provide sputum samples over several days to test for active TB bacteria.
This process can take several weeks because cultures require time to grow in a laboratory.
Specialist Referrals
Some applicants are referred to a respiratory specialist or pulmonologist for further evaluation.
The specialist may review imaging results, assess symptoms, and determine whether treatment or monitoring is necessary.
Repeat Imaging
In certain cases, repeat chest X-rays or CT scans may be recommended to clarify uncertain findings.
Preparing early and providing complete medical information can help avoid unnecessary delays in your application.
