Medical Inadmissibility Canada: Excessive Demand Explained (2026)

Medical inadmissibility Canada rules can lead to your immigration application being refused because of a health condition. Medical inadmissibility applies to anyone applying to visit, study, work, or live permanently in Canada, and there are only three grounds: danger to public health, danger to public safety, or excessive demand on Canada's publicly funded health or social services. Most refusals people worry about fall under that last one.

The important thing to understand up front is that excessive demand is a cost test, not a secret list of banned diseases. IRCC does not refuse you simply because you have a diagnosis. It refuses you only when the projected public cost of your care crosses a set dollar line, or when your care would add unreasonably to wait times for services in Canada.

The three grounds for medical inadmissibility in Canada

Under Canadian immigration law, a medical officer reviews your immigration medical exam results and can find you inadmissible on one of three grounds set out on IRCC's official medical inadmissibility page:

1. Danger to public health: an infectious condition such as active tuberculosis or active syphilis, or contact with others who have one, that could affect people living in Canada.

2. Danger to public safety: a risk of sudden incapacity or unpredictable or violent behaviour.

3. Excessive demand on health or social services: care that would likely cost more than the annual threshold, or add unreasonably to wait times for publicly funded services.

The excessive demand cost threshold in 2026

For 2026, IRCC's excessive demand cost threshold is $144,390 over five years, or $28,878 per year. IRCC compares the projected public cost of the health and social services your condition would need against that five-year threshold. If the projection stays under the threshold, excessive demand is not a problem, even if you have a serious diagnosis. If it crosses the line, the officer can find you inadmissible on that ground. The threshold is updated periodically, so always confirm the current figure on the official IRCC page before relying on it.

Who is exempt from excessive demand

This is where a lot of family worry is misplaced. The excessive demand rules do not apply to several groups. Refugees and their dependants, protected persons, and certain people being sponsored through family sponsorship, specifically dependent children, spouses, and common-law partners, are not assessed for excessive demand at all. In practice, that means a sponsored spouse or a dependent child with a costly condition generally cannot be refused on the excessive demand ground.

One caution: these exemptions cover excessive demand only. The danger to public health and danger to public safety grounds still apply to everyone, including sponsored family members.

From Amir's desk: what medical inadmissibility really comes down to

In practice, the panic I see is almost always about the wrong thing. People assume a diagnosis of diabetes, cancer, or a developmental condition is an automatic refusal. It is not. Excessive demand is arithmetic: IRCC estimates the five-year public cost and compares it to a threshold that most conditions never reach. The cases that get refused are the ones where projected costs are genuinely high and no one answered the officer's numbers.

The second thing people miss is that the procedural fairness letter is an opportunity, not a verdict. When IRCC believes you may exceed the threshold, it is legally required to send you that letter and to genuinely consider what you send back. That is the moment to submit a realistic mitigation plan and, where it applies, evidence of your ability and intent to cover costs privately. In decisions like Sapru, the courts have held that the officer must actually weigh a person's ability and intent to offset the costs, and that the fairness letter has to give a real chance to respond. And even where an excessive demand finding stands, family-class and humanitarian relief has succeeded, as it did in Mudarth. The refusals that stick are usually the ones where the applicant treated the letter as final and never engaged.

How to overcome medical inadmissibility: the procedural fairness letter

If a medical officer believes you may be inadmissible, IRCC sends a procedural fairness letter before any final decision. It explains the concern and gives you the chance to respond. You have 90 days from the date of the letter to submit information, and you can request an extension if you cannot meet that date. You are allowed to get professional help to respond, though it is not required.

Useful evidence includes an updated medical diagnosis, proof of treatment that has cured or improved the condition, a change to lower cost medication, or the real cost of the medication and services you actually need. Where it applies to your situation, IRCC may also invite you to submit a mitigation plan showing how the demand on public services would be reduced. This 90-day window is the single most important stage, and a thin or late response is the most common reason a fixable case becomes a refusal.

Share how you approached it in the comments, keep it general, real experiences help others in the same spot.

Medical inadmissibility is a refusal of your immigration application because of a health condition, on one of three grounds: danger to public health, danger to public safety, or excessive demand on Canada's health or social services. It is decided from your immigration medical exam.

What medical conditions are inadmissible to Canada?

There is no fixed list. Infectious conditions like active tuberculosis can raise a public health concern, and high-cost conditions can raise an excessive demand concern if projected costs exceed the threshold. Most conditions do not make you inadmissible on their own.

What is the medical inadmissibility threshold in 2026?

IRCC's 2026 excessive demand cost threshold is $144,390 over five years, or $28,878 per year. If the projected public cost of your care over five years stays below that figure, excessive demand does not apply.

How do you overcome medical inadmissibility?

Respond fully to the procedural fairness letter within 90 days. Submit updated medical evidence, lower cost treatment options, and, where invited, a mitigation plan showing your ability and intent to reduce the demand on public services.

Are sponsored spouses and dependent children screened for excessive demand?

No. Sponsored spouses, common-law partners, and dependent children, along with refugees and protected persons, are exempt from the excessive demand rules. They can still be assessed on the public health and public safety grounds.
