Read the general life across the border overview
Hypothetical example: Véronique is being transferred by her Saint-Lucien employer on a specialized-knowledge petition. Her husband Emmanuel is a Canadian permanent resident and a citizen of Cameroon; their daughter is nineteen and their son is twenty-two. The household thinks of itself as one file. It is four, and the answers diverge on three different rules: the category the principal holds, the age of each child, and the fact that a spouse’s permission comes from the marriage rather than from his own passport.
The spouse’s permission comes from the category, not the passport
Emmanuel’s Cameroonian citizenship is irrelevant to whether he may accompany Véronique, because derivative status flows from the marriage to the principal. What his citizenship may affect is procedure, such as whether he needs a visa and what documentation a consular post asks for. The substantive point is that in this classification an accompanying spouse is employment-authorized incident to status, so he may work. Had Véronique been admitted instead under the professional category of the trade agreement, the answer would reverse: dependants there may study but may not be employed at all, and no waiting period changes it.
Two children, one boundary between them
Derivative eligibility for a child ends at twenty-one, and it ends whether or not the child is still in school or still supported at home. The nineteen-year-old can accompany the household now, and the family should count how many months of the assignment remain after her twenty-first birthday, because her status ends there and anything she is enrolled in ends with it. The twenty-two-year-old cannot be a derivative at all. His options are his own: a student route with its own admission and financial requirements, an employment-based category if an employer will petition, or remaining in Canada. Starting on his file first is usually the right sequence, because it is the slowest.
What changes if the principal’s category changes
Every derivative status is borrowed, which means the household’s permissions move whenever the principal’s do. If Véronique reaches the five-year limit of her classification, or the corporate relationship behind the petition ends, the family’s status ends with hers rather than continuing independently. If she later moves to a treaty-investor position, the spouse remains employment-authorized but the ownership and control requirements of that route become the household’s concern. If she pursues permanent residence, spouse and unmarried children under twenty-one may be included as derivatives on that process, with the age rules applying again. Mapping those transitions in advance is what keeps a household from discovering them under pressure.
