TD status itself does not authorize employment. An eligible spouse or unmarried child under 21 may seek TD, but a spouse who wants to work needs a separate status or work authorization to be reviewed on its own facts.
Treat remote work as work, not as a side detail
Include a spouse's plan to keep working remotely for a Canadian employer from inside the United States; the employer being Canadian does not supply permission on its own. TD dependants may study, but TD status does not authorize employment. Record a child's school plans and age separately from the parents' status questions, and note whether the household intends to arrive together or in stages.
Make a household activity list before travel dates are fixed. It should separate the principal’s proposed work from every dependent’s proposed study, remote activity, or later arrival. Hypothetical example: a clinical-trial coordinator expects to begin TN employment in June, while the spouse plans to continue paid online bookkeeping from the United States. The family should obtain advice about the spouse’s separate work authorization question before treating the move as routine. A dependent classification does not turn independent paid work into authorized work. The TN principal’s case also must remain tied to professional employment for the U.S. employer, rather than an arrangement in which the principal operates an independently owned U.S. business.
