"As might be expected in Canada, vaccination policies are as diverse as the geogra-high immunization rates by educating their populations about the benefits of vaccines. Just three have legislated vaccination policies, applying strictly to children about to enrol in school. Ontario and New Brunswick require immunization for diphtheria, tetanus, polio, measles, mumps, and rubella immunization, while Manitoba requires a measles vaccination.
In each case, though, the legislation includes an exemption clause. Essentially, each of the three provinces allows parents to request that their child be exempted from the vaccination requirement on medical or religious grounds, or simply out of conscience. In such instances, in the event of a disease outbreak, unvaccinated children can be excluded from entering a school." - Mandatory vaccinations: The Canadian picture (part of a three-part series on mandatory vaccination)
