Processing times vary by petition type, project and country of chargeability, and they change, so current published information should be checked rather than an estimate assumed. The relevant planning question is what the owner does with the Ontario business during a wait measured in years and what happens once residence begins.
Plan the handover before the petition
Work out now who runs the Ontario operation once residence begins, because that decision cannot wait until an approval arrives. The realistic options are to sell, to install a manager, or to wind the business down, and each has its own timeline, tax treatment and effect on the family's income. Decide also what happens if the process takes longer than expected: whether the owner keeps operating as now, whether any child will age out in the meantime, and whether the capital is committed in a way that can tolerate the wait. Keep the source-of-funds records intact throughout, since they may be needed again at the conditions-removal stage, and note where each document is kept.
Hypothetical example: a Tyendinaga family wants a child to begin U.S. university soon after an immigrant investment is made. Work backward from the child’s education date, but do not confuse a petition filing with residence. The investment, adjudication, visa or adjustment stage, conditional period, and later removal-of-conditions filing each have their own evidence needs. Choosing a school before checking the immigration calendar can create a costly mismatch. That comparison may lead the family to use a different education arrangement while the immigration process follows its own statutory stages.
