Not as a dependant. A spouse admitted in TD status is not employment-authorized, regardless of qualifications or of whether a job exists. Any employment would require the spouse's own independent status, assessed on that spouse's own facts.
Test the second application before relying on two incomes
In hospitality it is common for both partners to work in the industry, and an employer may well be willing to hire both. The willingness does not change the position: a dependant cannot work, so the second person would need their own application on their own qualifications and their own offer. That is realistic in some cases and not in others, and it takes its own preparation time. Establish which it is before the household budgets for two salaries. Children in dependent status may attend school and cannot work, and derivative status covers unmarried children under twenty-one. If a child is close to that age, raise it with counsel at the start, since the limit falls on a date that no planning can move.
Hypothetical example: Leona is a pharmacist with a U.S. offer, and her partner expects to keep a Canadian remote job after the move. The opening assessment separates the principal's proposed TN work from every family member's own immigration and employment position. Passports, relationship records, ages, school plans, and any separate job offers are the records to organize first. Decide before travel whether the household is relying on dependent status or whether another adult needs an independent work-authorized route. Problems often arise when a family budget assumes that a dependant may begin American employment immediately. A dependent's school attendance and a partner's separate qualifications are different questions; neither is resolved by the principal's offer letter.
