No. Verify the current official terms and the family's own admissibility first, take Canadian tax advice on the specific disposal, and only then act. A land sale made on an assumed deadline cannot be reversed if the assumption is wrong.
Nothing irreversible before verification
Hypothetical example: a Hampton family are told terms will tighten within weeks and begin arranging to sell a parcel of farmland and wind down a lease to free up funds. Each step lands its own consequence in Canada straight away, from tax on the disposition to the income the lease was producing, and neither can be walked back.
That this framework's stated conditions have shifted since launch cuts two ways: a cut-off might genuinely exist, and precisely because conditions move, a cut-off has to be read off the government page rather than taken from a person whose fee depends on the rush. Establish the conditions, establish that each member of the household is admissible on the ordinary grounds, take the accountant's advice, and hold the land until all of that is written down and dated.
