No. The stated expectation is not a guarantee, permanent residence is not granted until the process completes, and an applicant should keep her Canadian home and affairs intact until she holds status and has had tax and residency advice.
Sequence the move after the status, not before
The official FAQ describes a process expected to take weeks once the fee and application are received, assuming documents and payments are submitted promptly. That is an expectation published by the program, not a commitment enforceable by the applicant, and vetting or admissibility questions can extend it. Selling an Ontario home, closing Canadian accounts or ending provincial health coverage before status is granted leaves the applicant exposed if the process stalls. A safer sequence is: confirm admissibility, pay the fee, complete vetting, make the gift only when asked, receive status, and then take tax advice on the date of U.S. residency and its Canadian consequences before disposing of property. Becoming a permanent resident also creates obligations to maintain residence in the United States; a retiree who plans long Canadian summers should understand the abandonment rules before choosing this route at all.
Hypothetical example: a physiotherapist sells a Canadian clinic after reading a published processing expectation. The first review should separate the irreversible sale date from the uncertain vetting and immigrant-processing dates, and obtain cross-border tax advice before changing residence. Signed sale documents and the actual status notice settle when the applicant can restructure life, not a general timetable. Keep housing, insurance and Canadian business arrangements reversible until permanent residence is granted. A payment by the applicant to the U.S. government starts no interim authorization to live or work in the United States.
