Read the general eligibility basics overview
Hypothetical example: When a Torbay household contains a Canadian citizen and a permanent resident who is a citizen of the United Kingdom, the two adults have different U.S. options and the household should not assume the citizen's route carries the other. The citizen may use TN in a listed profession; the permanent resident may not, but as a UK national has E-2 treaty eligibility in their own right. Marriage does not confer Canadian citizenship, and a pending citizenship application does not either. Each adult's route is assessed separately.
What each nationality opens
Hypothetical example: the Canadian citizen in the Torbay household is a university research technician with a science degree and a U.S. laboratory offer, and the permanent-resident spouse, a UK citizen, ran a small landscaping company before moving to Canada and would like to do the same in the United States. The citizen's route is TN if the position fits a listed profession. The spouse cannot use TN, because permanent residence is not citizenship, but E-2 treaty eligibility follows the spouse's own nationality, and the United Kingdom is a treaty country. That means the spouse could, with an investment at risk in a U.S. landscaping business they own and direct, apply for E-2 as a principal, independent of the citizen's status.
Why the dependant route may be the wrong default
The obvious plan is for the citizen to obtain TN and the spouse to enter as a TD dependant. That works for residence but not for the spouse's business, because TD status does not permit employment or self-employment. The household would then have one income and a spouse whose skills sit idle. The alternative is two principals: the citizen on TN and the spouse on E-2, each with their own application, evidence and timeline. E-2 requires a substantial investment irrevocably committed, a real enterprise that is not marginal, and treaty nationality of the investor and at least half the ownership. If the spouse's E-2 is granted, the citizen could instead be the E-2 dependant with work authorization incident to status, which is worth comparing.
Citizenship timing and the Canadian obligation
A Torbay permanent resident who becomes a Canadian citizen gains TN eligibility and Canadian treaty nationality, but only when the certificate issues; until then nothing changes. Time spent in the United States counts against the physical-presence requirement for Canadian citizenship and against the permanent-resident residency obligation, so a long U.S. stay in TD or E-2 status can delay or endanger the Canadian side. The household should decide whether completing citizenship first is worth the wait, and should keep the permanent-resident spouse's Canadian status in view throughout. Children follow whichever parent is principal as TD or E-2 dependants, may study, and may not work; each child's own citizenship should be recorded too, since a child may be a citizen of one country and a permanent resident of another.
