TD does not authorize employment, including remote work performed while physically in the United States. A brief stay does not create a work benefit.
Review the actual household activity
Identify the spouse’s proposed duties and any independent category being considered. A Canadian employer or payment account does not itself resolve permission. The dependent category is for a qualifying spouse or unmarried child under 21; each person needs valid status.
A spouse who intends to work needs a route of their own, assessed on their own occupation and qualifications, which may be a separate professional request if their occupation is listed and they hold the qualification the entry names, or a different category entirely. If a spouse expects to work, discuss that as a separate authorization question, since TD status alone does not provide it, and coordinate school or childcare timing around the same two-checkpoint sequence as the principal case. Start the spouse's assessment first where the household's finances depend on the second income, because it is the longer and less predictable of the two enquiries and it may return an answer that changes the whole plan.
