No. TD is an accompanying status, not an employment-authorized one, and it does not become one because the spouse is experienced, certified in Québec or urgently needed by a willing employer. A spouse who intends to work needs a classification assessed on her own citizenship, occupation and arrangement.
TD admits the family and stops there
Households get caught by this because other categories behave differently and because families reason about themselves as a single unit with a single plan. Dependants of a TN professional may accompany the principal and may study while holding that status; unmarried children under twenty-one qualify as dependants, and the status carries no work authorization for any of them. The consequence is financial and should be modelled before departure rather than discovered afterwards. Where the second income was assumed rather than authorised, the household finds out in the first month, in a country where it has no other support.
Hypothetical example: a Roxton Pond household plans a move where one spouse holds a listed profession and the other has spent nine years running dry kilns and grading hardwood, and has an informal offer from a flooring mill near the destination. Two timelines are needed, not one. The principal’s runs through the listing, the credential and the employer letter. The spouse’s begins with a separate question: is her occupation listed, does another category fit her arrangement, and how long does that route take. A signed offer is evidence of an employer’s wish, not of anybody’s authorization to work.
