Unvaccinated children under 12 years of age
If you qualify as a fully vaccinated traveller, your unvaccinated children must follow specific requirements when you return to or enter Canada. This applies to unvaccinated children under 12 years of age who are accompanying a parent, step-parent, guardian or tutor who qualified as a fully vaccinated traveller when they entered Canada.
For the next 14 days, the children:
- must take pre-entry, arrival and Day-8 tests (unless under the age of 5)
- can’t attend school, camp or daycare
- can’t attend large crowded settings, indoors or outdoors, such as an amusement park or sporting event
- can’t take buses, subways, trains or other crowded transportation must follow all the requirements in the children’s handout provided at the border
