Wellington Dufferin Guelph public health suspended 630 high school students Wednesday because their immunization records were not up to date.
Ontario law requires parents to immunize their children and provide proof of it to public health if they want their children to attend school.
Students will remain suspended until a parent provides an immunization form, an exemption form or once 20 days run up, whichever comes first.
Notices for elementary students will be sent out April 4, and currently 2400 students could face possible suspension.
