Health Canada States That Immunization is NOT Mandatory in Canada

"Unlike some countries, immunization is not mandatory in Canada; it cannot be made mandatory because of the Canadian Constitution. Only three provinces have legislation or regulations under their health-protection acts to require proof of immunization for school entrance. Ontario and New Brunswick require proof for diphtheria, tetanus, polio, measles, mumps, and rubella immunization. In Manitoba, only measles vaccination is covered. It must be emphasized that, in these three provinces, exceptions are permitted on medical or religious grounds and reasons of conscience; legislation and regulations must not be interpreted to imply compulsory immunization."
