How long are immigration medical exam results valid before they expire?

Immigration medical exam results are valid for a defined period set by IRCC policy, after which they expire and a new exam is generally required before an application can rely on medical results again. Because this validity period is set administratively and can be adjusted, the exact current length should be confirmed directly with IRCC or with the panel physician who conducted the exam, rather than assumed from a previous application or general impression.

Relying on an exam that has quietly expired since it was completed is a common, avoidable source of delay, particularly for applicants who completed a medical exam well before actually submitting their application, or who are trying to reuse an older exam for a new, later application. The gap between when an exam is done and when it is actually used matters here.

Anyone relying on a previously completed medical exam, especially one done some time ago, should confirm its current validity status before submitting or relying on it in a new application, so that a fresh exam can be arranged in time if the old one has already expired.
