In-Canada applicants
We’ve put in place a temporary public policy for immigration medical exams (IMEs) until October 6, 2024.
If you completed an IME within 5 years of submitting your new application, include the IME number (or the unique medical identifier number) from your previous exam in your current application.
You may be exempt from completing another IME if you meet all of these conditions:
You applied, or are applying, for either permanent residence or temporary residence.
You already live in Canada.
You completed your previous IME in the last 5 years.
Your previous IME indicated a low risk or no risk to public health or public safety.
