Canada on the whole is a safe country when it comes to disease and illness.
Communicable diseases, such as the bubonic plague, typhoid or malaria, are non-existent in Canada. Normally, the biggest fear Canadians have in the way of airborne communicable diseases is a bad cold or the flu.
West Nile Virus has become a concern in the last few years, but precautions can be taken and the number of people affected in Canada is very small.
Canada also has a very good health care system through which Canadians have access to essential medical services for no charge.
