Registration alone does not establish the required ongoing business. Describe the actual operations and have the qualifying organization assessed under the applicable rules.
Show business activity rather than an address
Identify what goods or services are provided and the arrangements supporting that work. Do not assume a mailing address or agent establishes all the required activity. The proposed role and employment history remain separate questions.
Registration and business activity answer different questions, and a certificate of status can be read in seconds. What takes longer to assemble, and is worth assembling, is the ordinary evidence a going concern generates: signed customer agreements with dates, invoices issued and paid in the relevant period, payroll or contractor records for the people doing the work, and any lease or service agreement for the space in which it happens. Hypothetical example: a firm that runs a medical simulation laboratory keeps its Canadian registration and its equipment while transferring its manager, and the question becomes whether courses are still being delivered to clients there, by whom, and under what contracts.
Treat the qualifying relationship and the proposed managerial or executive duties as separate exercises with their own documents, rather than assuming proof of continuing activity carries all three. Where an operation runs largely on subcontractors, name them and produce their agreements, because a workforce nobody employs directly still has to be visible somewhere in the record. Ask, too, what the entity would look like on the day after the transfer, since that is the state the plan is being asked to describe.
