Yes, that is a legitimate household arrangement to describe. TD status does not authorize employment for an accompanying spouse in any case, and a spouse who remains in Ontario to manage a farm or business has their own separate situation to document.
Record who is actually going and who is actually staying
Write out each person's plan explicitly: who travels to the United States, who remains in Ontario, and what that means for the farm or business. Do not assume the household automatically relocates together. Note any children's schooling and status questions separately from the farm-management arrangement.
Build a person-by-person chart covering citizenship, intended location, activity, and proposed status. The TN principal must independently meet the professional rules; the Ontario spouse's decision to keep operating a business neither creates nor defeats that eligibility. If relatives later accompany the principal, a TD spouse and children cannot work in TD status, although they may study; they may work only if otherwise authorized by DHS. A common error is describing the family as relocating together when one person will remain behind, then using documents that imply incompatible schedules. Keep marriage, birth, schooling, and management records aligned with the actual plan.
Hypothetical example: A civil engineer accepts an American infrastructure assignment while her husband remains near Strathroy-Caradoc to run their beekeeping operation. Their teenager may join after a school term. The application materials state those separate dates and roles. If the husband later seeks TD admission, he does not perform U.S. work on that status; the family reassesses authorization before changing the arrangement rather than assuming marriage extends the engineer's work permission to him.
