Read the general life across the border overview
Hypothetical example: the Okonkwo family from Innisfil is preparing for a treaty investment in an American business. Their eldest is twenty, the youngest is fourteen, and the parents assume that whatever applies to them applies to the household. Dependent status is granted to a spouse and to unmarried children under twenty-one, the spouse's ability to work is treated differently from the children's, and school attendance is a separate question again from work authorization. Hypothetical example: Chioma, a marine-insurance broker, must decide whether her partner needs an independent work route while their eldest child approaches the age limit. The decision is whether each family member can meet the travel, school, work, and age consequences of the principal’s category. A derivative classification is not a blank authorization: work rules differ by category, and an unmarried child’s eligibility is tied to age.
The spouse and the children are not in the same position
A qualifying spouse in this route is employment-authorized incident to status under current policy, with the position evidenced by the notation on the arrival record. Children in dependent status are not employment-authorized at all, regardless of age or ability. Families frequently conflate the two because both are described as dependants. The practical step at admission is to check what each family member's record actually says, and to raise any discrepancy at the time rather than after an employer or a school has asked a question that the record cannot answer. Create a family calendar that records passport expiry, anticipated travel, school enrollment, and the oldest dependent’s age threshold. It helps identify when a principal extension, a spouse’s work plan, or a child’s independent status needs attention.
Twenty-one is a date, not a negotiation
Derivative status for children rests on being unmarried and under twenty-one. For a twenty-year-old, that means the family should be planning now for what happens on a specific date that will arrive during the assignment. The options depend entirely on the individual: a student route, an independent qualification, or a return to Canada are all possibilities to discuss with counsel well in advance. What does not work is discovering the limit in the month it applies. Write each child's date of birth into the planning documents alongside the business milestones, so it is visible whenever the timeline is reviewed. Ask first which category the principal will hold, then examine the dependent rules that follow. A spouse and child may have different practical choices even when admitted together, and a child’s attendance at school does not establish employment permission.
Study is permitted, and it is not the same as work
Children in dependent status may attend school, and that is often the family's most immediate practical concern. It is worth separating it clearly from work authorization in every conversation, including with schools and employers who may not know the distinction. A teenager taking paid summer work is doing something different from attending classes, and the answer is different too. If an older child wants to work, the honest starting point is that dependent status does not permit it and that any independent route would be assessed on that child's own qualifications and circumstances. Do not defer the family discussion until a move is booked. The best outcome is a documented sequence for the principal’s filing or entry, each dependent’s documents, and any independent route a spouse or older child may need.
