There is no existing Canadian law on the books that mandates an age requirement before a person may work as a babysitter, according to the Public Legal Education Association. However, parents may consider age, maturity and experience before hiring a babysitter.
Canadian law forbids a minor under the age of 16 years old to babysit during school hours without permission from her school principal, states PLEA. Parents can decide whether to set an age requirement for the babysitter they employ and also may choose a sitter based on age and number of their children and the length of the assignment. PLEA states that it is ultimately the responsibility of the parents to care for their children appropriately within the law.
