The spouse needs the appropriate individual status and documentation. A supplier contract or invitation does not create that permission. If a spouse expects to work, the plan should rest on that person's own documentation rather than on the transferring employer's supplier relationships. Nothing in a commercial contract between two businesses confers permission on a family member. Treat the two questions as unrelated, because they are.
Review the planned activity separately
Qualifying L spouses are employment authorized incident to status, with appropriate evidence. Children do not obtain work authorization solely through L dependent status. Include any proposed role with the supplier or employer in the family assessment.
Household planning benefits from the same record discipline the rest of the file uses. Write down, for each family member, the status relied on, the document evidencing it, and its expiry. A qualifying L spouse is employment authorized incident to status with appropriate documentation; a dependent child is not, and study permissions follow separate rules.
Where a spouse holds a professional role in Canada tied to a supplier or distributor, ask whether continuing that role remotely raises questions of its own, and put the arrangement in front of counsel rather than assuming remote work is invisible. Dependent eligibility also turns on marriage and on a child being unmarried and under twenty-one, so those dates belong in the same note.
