Throughout. Conditional permanent residence runs for two years and ends with a filing that must be supported by evidence about the enterprise and its jobs, so the hiring plan and the record-keeping have to be working from the start of operations rather than assembled near the end.
Treat the two-year period as the evidence-gathering period
The conditional period is not a waiting room. It is the window in which the business has to become the thing described in the filing, and in which the documentation of that has to be created. Plan hiring against that horizon deliberately: when each position starts, how it is evidenced, and who is responsible for keeping the records.
Delays in opening, a slow first season or a decision to postpone hiring all consume the same fixed period. Build in margin rather than assuming everything opens on schedule, and review the position with counsel well before the period ends, not in the month the further filing falls due. A deliberate review halfway through the period is usually the most useful one anybody does.
Hypothetical example: Dalia is funding a U.S. manufacturer of compostable medical packaging after liquidating a Canadian share portfolio. A timing review should link the sale records, tax evidence, currency transfers, project subscription and job-creation schedule in the order they actually occurred.
The business plan and capital-transfer documents set the factual chronology. Avoid rushing a filing before the chain is documented merely to meet a hoped-for move date. Approval of the investor petition is not residence by itself; immigrant-visa or adjustment steps follow, and conditional residence later requires proof that the capital and job-creation requirements have been met.
