Not specifically. I can, however, make two comments based on my limited knowledge of tax matters.
First, contributions that are not repaid as they should be over 15 years, a period that begins two years after the funds are withdrawn, are added to the person's income, and that amount is taxable.
Secondly, the tax rules on capital gains exemptions have been tightened up recently. It is also very clear that taxpayers will have to declare property sales in their tax returns. This is something new. The capital gains exemption rules for assets other than a principal residence apply and are already in force.
As to a person who owns a principal residence and another residence that is deemed a secondary residence, the current rules already limit possible gains, and the government can tax that person under the current rules.
There are of course always financial arrangements. There are tax specialists and professionals who can be very creative in order to achieve certain things, while fully complying with the spirit of the law. Our suggestion, however, is intended to help children access funds that their parents have already accumulated, but that are not available in a chequing account.
