Do not fall for these threats of vaccine mandates. They are bluffing in order to scare everyone into getting them.

FACT: There is no precedent for vaccine mandates in Canada.
"Some provinces also impose mandatory vaccinations on schoolchildren. Ontario, for example, even prior to the pandemic, required children to receive nine inoculations in order to attend primary and secondary school, although there are exemptions for conscience, religious or medical reasons. Other provinces, such as Alberta, do not insist upon vaccination for students."

"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)"
