As part of the Canadian government’s efforts of protecting the health, safety and wellbeing of Canadians, and to reduce the excessive demand on Canada’s health and social services, The IRCC (Immigration, Refugees and Citizenship Canada) has set federal regulations that requires permanent residency applicant as well as some temporary residency applicants and refugees to undergo a medical examination which can include a physical and mental examination, review of past medical history, and laboratory and diagnostic tests, which can be done by a delegated medical officer by the IRCC.
There are 3 major reasons which can cause applications to be refused due to medical reasons:
1- Danger to public health: If the applicant has a condition that could endanger the public health in Canada, such as certain infectious diseases like active tuberculosis or syphilis and any other disease which can affect other people living in Canada they will not be admissible to immigrate to the country.
2- Danger to public safety: applicants who under the risk of sudden incapacity or who can have violent behavior that would create danger to the safety of other people living in Canada, such as mental health problems like certain sociopathic behavior disorders, sexual disorders, and types of hostile disruptive behavior, they can be considered medically inadmissible to Canada.
3- Excessive demand on health and social services: applicants can be refused based on their medical tests if their health condition would negatively affect the waiting times for services in Canada, or if the treatment and management costs of their health condition exceeded the excessive demand cost threshold published by the federal government, which is calculated on a yearly basis based on the average Canadian cost for health and social services, the cost threshold is three times the Canadian average cost, it is important to note that refugees and their dependents, dependent children and spouses are exempted from being inadmissible based on the excessive demand rule.
