No. The actual result depends on required submissions, vetting, eligibility, admissibility, and visa availability, and general processing language on a government page is not an individual guarantee for any specific applicant.
Keep every commitment conditional on established milestones
Follow current official instructions closely and keep copies of all communications and submitted records. Identify what would change in the household's plans if additional information or a further step is required, and recheck the framework's current terms before acting, particularly if family circumstances or the proposal itself change before the gift is made.
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. Where the official material describes processing measured in weeks, treat that as description rather than a promise, since approval and timing are never guaranteed. The program's timing, application steps and any changes are published by the government, and a decision this large should follow verification and independent legal advice, not a deadline someone else sets.
