No. The official FAQ currently says the process should take weeks, but it gives no guaranteed completion date, and permanent residence still depends on EB-1 or EB-2 visa availability and standard immigrant processing. Plan around milestones actually reached, and keep housing, school and business decisions reversible until residence is granted.
Milestones are known; durations are not
Hypothetical example: a Haldimand County contractor reads the official Gold Card process and pencils in a move for next spring. The framework as published describes an application and fee, vetting, a gift on instruction, and immigrant processing through EB-1 or EB-2. Its FAQ says the process should take weeks, but it does not guarantee completion by a particular date, and visa availability in those categories is governed by the monthly Visa Bulletin.
A realistic plan treats each stage as a trigger: sign a lease only after the immigrant visa is issued or adjustment is approved; enrol children in U.S. schools only when the family's admission date is known; wind up Canadian affairs, including any farmland or business sale, on the same trigger. Until residence is granted, the process itself confers no U.S.
status, and the applicant remains a visitor when travelling south. Re-read the official page at each milestone, since its terms are dated, and time any business sale funding the gift to the instruction to pay, not to an assumed approval.
