Receiving a positive immigration tuberculosis test raises important questions about your application status and next steps. While this outcome requires careful attention and compliance with specific protocols, understanding the process can help reduce anxiety and ensure successful navigation of the requirements.
The distinction between active and latent tuberculosis infection and the medical surveillance process determines your path forward. Most importantly, a positive result does not automatically disqualify you from Canadian immigration.

Why Does Canada Require Tuberculosis Testing for Immigration?
Canada conducts thorough health screenings to safeguard public health while treating applicants fairly. Immigration, Refugees and Citizenship Canada (IRCC) mandates that all permanent residence applicants, and some temporary residence applicants, undergo an immigration medical exam (IME). This exam screens for active TB using a chest X-ray for everyone aged 11 and older and may include TB infection testing for certain high-risk individuals.
The IME requirement for temporary residents depends on the length of stay in Canada, the type of work, and the time spent in countries where TB is common.
The purpose of the immigration medical examination (IME) is to "identify those who may pose a risk to public health or safety, or may place excessive demands on Canadian health and social services".
What Types of TB Tests Are Used?
Panel physicians employ several diagnostic methods during your immigration medical examination:
Primary Screening:- Chest X-ray (required for ages 11+)
- Physical examination for TB symptoms
- Medical history review
Additional Testing for High-Risk Groups Only:
All individuals in a TB high-risk group: If ≥2 years of age: IGRA testing (or TST if IGRA unavailable).
The high-risk groups specifically include those with:
- HIV infection
- Chronic kidney disease requiring dialysis
- Solid organ transplant candidates or recipients
- Planned TNF-alpha inhibitor therapy
- Abnormal chest x-ray consistent with prior TB
IGRA or TST are not routine parts of the standard immigration medical exam and are limited to these specific high-risk categories.
How Do I Know if I Have Active or Latent TB?
Active TB Disease
When Mycobacterium tuberculosis bacteria actively multiply in your body, this creates active TB disease. Active TB in the lungs or throat can be transmitted to others when an infected person coughs or sneezes.Key characteristics include:
- Presence of TB symptoms (persistent cough, weight loss, fever, night sweats)
- Potential to transmit infection to others
- Requires immediate medical intervention
- Temporarily delays immigration until successful treatment completion
Individuals diagnosed with active pulmonary or laryngeal tuberculosis (TB) need to complete treatment before entering Canada to ensure they are no longer contagious.
Latent Tuberculosis Infection
Some people carry TB bacteria in an inactive form and never develop symptoms. You might not be aware you have it because latent TB does not cause illness. Although it is not active now, there is a possibility it could become active later in life.Latent TB infection means:
- No symptoms present
- Cannot transmit infection to others
- May require monitoring after arrival in Canada
- Generally allows immigration with certain conditions
Understanding this distinction helps explain why different positive results lead to different immigration pathways.
What Happens When My Immigration TB Test Is Positive?
Your panel physician will take several important actions following a positive test result:
- Determine TB type through additional diagnostic testing
- Assess transmission risk and symptoms
- Classify your medical examination according to IRCC standards
- Provide clear instructions for your specific situation
This systematic approach ensures appropriate care while maintaining immigration processing efficiency.
What If I Have Active TB Disease?
If diagnosed with active tuberculosis, you must complete treatment before immigrating to Canada. Applicants identified as having active TB abroad are denied entry to Canada until they have completed a satisfactory course of treatment and have been reassessed.
Active, infectious TB can lead to medical inadmissibility for danger to public health. Applications are typically not approved until treatment is completed and you're no longer infectious.
Treatment Requirements:
- Anti-tuberculosis medication regimen under medical supervision
- Regular monitoring through medical evaluation
- Before they can be approved for entry into Canada, applicants must provide evidence of completed TB treatment, three consecutive negative sputum smears and cultures, and chest X-rays showing stable or improving results.
- Final medical clearance from your panel physician
Timeline Considerations:
- Immigration processing pauses during treatment
- Processing timelines vary based on individual circumstances and treatment response
- For every confirmed case of active pulmonary TB, contact screening must be carried out according to the IRCC tuberculosis technical instructions for all family members or close contacts who are also immigration applicants
While this represents a significant delay, completing treatment ensures your health and eligibility for Canadian immigration.
What If I Have Latent TB?
If active TB is excluded but signs of inactive TB or latent TB infection (LTBI) are present, the individual may be granted medical clearance for Canada with a visa condition requiring them to undergo medical surveillance after arrival.
This conditional approval means:
- Immigration processing continues normally
- Medical surveillance requirement added to your file
- Compliance becomes mandatory after Canadian arrival
- No immediate impact on your application timeline
This balanced approach protects public health while allowing immigration to proceed.
What Is Medical Surveillance and When Do I Need It?
Medical surveillance is a follow-up health assessment for newcomers to Canada to ensure that inactive tuberculosis has not developed into active TB. It is mandatory for anyone identified with inactive TB during their immigration medical exam (IME). Currently, inactive TB is the only condition that triggers a requirement for medical surveillance.
Who Requires Medical Surveillance?
Standard eligibility criteria include:- Evidence of inactive pulmonary TB on chest x-ray
- History of previously treated TB infection
- Extra-pulmonary TB findings
- Recent contact with an active TB case
Groups That Face Higher Risk
People with a positive pre-landing IGRA or TST who have an elevated risk of TB reactivation, such as those with chronic kidney disease, HIV, a history of certain head and neck cancers within the past five years, or recipients of solid organ or bone marrow transplants on immunosuppressive therapy.
Certain individuals face elevated TB reactivation risk and require enhanced monitoring:
| Risk Category | Specific Conditions |
| Medical Conditions |
|
| Medical Treatments |
|
| Geographic Factors |
|
How Does the Medical Surveillance Process Work?
Step 1: Contact IRCC
After arriving in Canada, make sure IRCC has your current Canadian contact information and then wait for your provincial or territorial public health authority to reach out. You should also send your contact details to IRCC’s Public Health Liaison Unit at IRCC.MHBSurveillance-SurveillanceDGMS.IRCC@cic.gc.ca.
Step 2: Public Health Contact
Each public health authority has its procedure and timeline for managing these appointments. It may take months for them to contact you.
Step 3: Comprehensive Health Assessment
Medical surveillance typically includes:
- History and physician examination for TB symptoms
- Chest x-ray evaluation
- Additional testing if symptoms or abnormal findings are present
- Discussion of preventive treatment options
Note: Specific procedures vary by province and local health authority.
How Long Does Medical Surveillance Take?
The duration of medical surveillance depends on the province and the local public health authority. Each authority follows its own process and schedule for appointments, so it may take several months before you are contacted.
In Ontario, the TB IMS process can take up to twelve months, but the average time is nine to twelve months.
Successful completion removes the condition from your immigration file.
How Does TB Testing Affect My Immigration Status?
If IRCC places you under TB medical surveillance, a “condition of landing” will be added to your immigration record. This condition is removed once you complete the required TB medical surveillance.
Important Protection (Ontario): In Ontario, a diagnosis of active TB does not impact your immigration status or that of your family members.
What Happens If I Don't Complete Medical Surveillance?
Failing to complete TB medical surveillance could affect your current and future immigration applications. Successfully completing the surveillance removes any related conditions from your file.
Can I Travel While Under Medical Surveillance?
If you plan to leave Canada before your provincial or territorial public health authority contacts you or before you complete medical surveillance, you should email the Public Health Liaison Unit to inform them that you will be traveling outside the country.
If you must leave Canada before completing medical surveillance:
- Notify IRCC's Public Health Liaison Unit immediately
- Include your full name and UCI number in communications
- Understand that the requirement remains active
- Expect border officials may inquire about compliance upon return
When Might I Be Refused Entry for Medical Reasons?
IRCC may deny your application if your health condition is considered a risk to public health. This determination is based on your immigration medical exam results. Grounds for medical inadmissibility include having certain infectious diseases, such as active tuberculosis or active syphilis, or recent close contact with someone who has an infectious disease.
Your Rights If You Receive a Refusal Letter
If IRCC determines that you may be medically inadmissible, you will receive a procedural fairness letter explaining the reasons. This letter is sent before a final decision on your application, and you have the opportunity to provide additional information in response. All responses must be submitted within 90 days of the letter’s date.
Which Groups Are Protected From Medical Inadmissibility?
Rules for medical inadmissibility based on excessive demand do not apply to refugees and their dependents, protected persons, or certain family-sponsored individuals, such as dependent children, spouses, and common-law partners. These exemptions balance humanitarian responsibilities with public health protections.
What About Healthcare Costs and Treatment Access?
Is TB Treatment Free in Canada?
TB treatment is provided free of charge across Canada, even if you do not have health insurance. This ensures that infectious disease prevention remains accessible regardless of financial circumstances.
Ontario Example: TB treatment is free, even if you do not have health insurance.
If you are diagnosed with TB infection, you can take free medication to prevent future illness.
How Much Does Medical Surveillance Cost?
The cost of medical surveillance varies by province and depends on your provincial health insurance coverage. In Ontario, TB IMS may be covered by the Ontario Health Insurance Plan (OHIP). For individuals without provincial coverage or other insurance, you are responsible for the medical check-up and tests, with costs potentially reaching up to $250.
How Do Modern TB Tests Work?
Difference Between Blood and Skin Tests
When initial screening suggests possible infection, advanced testing provides a clearer diagnosis:
| Test Type | Characteristics |
| TB Blood Test (Interferon Gamma Release Assay - IGRA) |
|
| Tuberculin Skin Test (TST) |
|
How Do Doctors Interpret Complex Results?
Healthcare providers consider multiple factors when evaluating positive test results:
Risk Assessment Includes:
- Country of origin and immigration status
- Personal medical history
- Age and immune system function
- Recent exposure to infectious diseases
This comprehensive evaluation ensures accurate diagnosis and appropriate care planning.
Special Considerations for Tuberculosis in Migrants
How Does Immigration Category Affect TB Requirements?
TB requirements vary depending on your immigration category. For example, refugees have about twice the risk of developing active TB compared to other immigrants after arrival. Other factors influencing TB risk among foreign-born populations include country or region of origin, particularly areas in sub-Saharan Africa, Asia, and the Western Pacific.
What About Time Since Arrival?
Recent immigrants face higher risks in the first years after arriving. Studies show rates are 5 to 10 times higher during the first year and about twice as high in years 1–4, compared with those who have been in the country for 5 years or more. This is why medical surveillance often focuses on these early years to ensure closer monitoring and timely care.
Documentation You Need to Keep
Maintaining complete records supports successful surveillance completion:
Treatment Records:
- Panel physician reports and recommendations
- Laboratory results including all TB testing
- Chest x-ray reports and imaging studies
- Proof of successful treatment completion
Surveillance Documentation:
- IRCC correspondence and appointment confirmations
- Public health authority communications
- Medical evaluation reports and follow-up plans
- Compliance verification letters
How Will This Affect Future Applications?
Proper documentation supports:
- Permanent residency renewals
- Citizenship applications
- Family member sponsorships
- Travel document requests
Complete records demonstrate compliance and facilitate processing.
What Are the Long-Term Health Outcomes?
How Effective Is TB Treatment?
Only a small proportion (<3%) of all active TB diagnoses among the foreign-born population made after arrival in Canada are identified during the immigration post-landing surveillance program.
Modern anti-tuberculosis treatment regimens demonstrate high success rates when completed as prescribed. Most people with latent infection never develop active disease, and those who complete treatment for active TB are typically cured completely.
What Happens After I Complete Medical Surveillance?
After completing medical surveillance, most individuals require no further TB-related medical monitoring unless they develop symptoms or risk factors change. Once you've had your appointment, the public health authority will inform the Public Health Liaison Unit at IRCC that you comply with your medical surveillance requirement.
For some cases where you had an immigration medical examination inside Canada and were seen by a tuberculosis clinic, you may not need medical surveillance. The public health authority may not contact you. If this is the case, the public health authority will notify the Public Health Liaison Unit at IRCC that you comply with your medical surveillance requirement.
Canadian healthcare systems provide ongoing support, ensuring access to quality care throughout your immigration journey and beyond.
