In most cases, the medical examination of Canadian visa extension notice is not strict. This is because Canadian visa officers are mainly concerned with the personal situation of the applicant and the integrity of the application documents when dealing with visa extension applications. However, for applicants who have suffered from some serious infectious diseases, Canadian visa officers need to provide medical certificates to prove whether the applicant's physical condition is suitable for continuing to live in Canada. In this case, the physical examination becomes relatively strict.
In addition, even under normal circumstances, if the applicant has any factors that affect his renewal during the application process, such as age and health status, the visa officer will require the applicant to have a physical examination to ensure that he meets the conditions for renewal.
