Not on TD status. A spouse and unmarried children under 21 may accompany the professional in TD status and may study, but TD confers no work authorization. A spouse who wants to work needs a category of their own.
What usually goes wrong
The recurring mistake is assuming that a spouse who works remotely for a Lévis employer from a U.S. address is somehow outside the rule. Hypothetical example: a Lévis welding inspector accepts a TN position at a U.S.
shipyard and his spouse, a claims adjuster, plans to keep her Québec caseload from their new apartment. Her employer's location does not change the fact that she would be performing work while present in TD status, and that is not something TD permits. The right move is to treat her plan as its own question: does her occupation appear in Appendix 2, does she meet its qualification, and would a U.S.
employer or her own employer's U.S. entity engage her? Children can enrol in school in TD status.
Everyone in the household should hold their own proof of citizenship and relationship evidence, since each person's admission is decided individually.
