To clarify, as the article linked in the OP was misleading.
From a government site:
Is immunization compulsory in Canada? Does my child have to be immunized?
Immunization is not compulsory or “forced” in Canada, but we do have regulations that help ensure that as many people as possible are protected by vaccines from the diseases they prevent. Some provinces require certain vaccines to be given before a child can enter school, but these are not mandatory in the usual sense of the term. Rather, parents (or children, if they are old enough to give consent) are required to declare a choice of whether to have their child (or themselves) immunized or not. If they choose not to, the child may be told that he or she must stay home from school if there is an outbreak of disease. This rule is designed to keep unimmunized children from getting sick and to keep the outbreak from spreading. School entry regulations also give parents an opportunity to bring their child’s immunizations up to date. Health care workers may also be required to have certain vaccinations, such as hepatitis B vaccine and an annual ‘flu shot’. If they refuse, they may be required to stay away from work during an outbreak. This practice protects their patients, who could be in grave danger if they became ill with a communicable disease.

From an anti-vax site:
Vaccinations are NOT mandatory in Canada. “Unlike some countries, immunization is not mandatory in Canada; it cannot be made mandatory because of the Canadian Constitution. Three provinces require proof of immunization for school entrance: Ontario and New Brunswick for diphtheria, tetanus, polio, measles, mumps, and rubella immunization; Manitoba for measles. But, exceptions are permitted on medical or religious grounds and reasons of conscience; legislation and regulations must not be interpreted to imply compulsory immunization.” (Immunization in Canada; May, 1997; Vol 23S4 and Canadian National Report on Immunization; 1996).
This means that nobody in Canada can be forced to receive a vaccination. In some cases, nursery schools, daycares, and other schools which are privately owned and operated can demand vaccination for enrollment. But publically-funded schools and daycares cannot.
Furthermore, Canadian Medical Law clearly states that healthcare recipients must be informed of all significant risks posed by any invasive medical procedure that carries a risk of injury or death. Vaccination is such a procedure; every Canadian must have received and understood all the information that is pertinent to the vaccination(s) to which they consent.

So the suspension being given in this case were about people who just got lazy with doing something either way – whether that be getting vaccinated, or stating that they wouldn’t be doing so.
