TD status itself does not authorize employment. An eligible spouse or unmarried child under 21 may seek TD, but any work the spouse intends to do needs its own separate route or authorization assessment, regardless of family ties to the area.
Treat each household member's activity as its own question
Include remote work the spouse intends to perform from the United States for a Canadian employer; the employer's location does not itself authorize that work. Children's schooling and any age-related questions also need individual attention. Clarify whether the household intends to arrive together or in stages, since that can affect what documentation each person needs at the border or consulate.
Confirm each family member's citizenship and civil documents early, since nationality determines which steps apply and marriage or birth certificates may need translation. Review the dependent’s own admission validity and the principal’s status if employment changes; do not assume any interruption causes immediate loss without checking applicable protections. If the extension crosses a school term or a planned return, decide early, and remember that TD permits study but does not authorize work, with proposed remote or unpaid activities requiring specific review.
