In Rosenthal v Rosenthal, 1986 CarswellOnt 288 (HCJ), it was held that an individual cannot take a position to obtain a tax benefit and then deny that position to obtain a different benefit.

At para 51 of Rosenthal, the court noted that “it is being argued that for the purpose of the Income Tax Act in 1969, the transfer of shares was not a gift, but for the purpose of the Family Law Act in 1986, the transfer of shares was a gift. Such a result should not be condoned by the court on the grounds of public policy alone.”

Further, the husband could not assert for tax purposes that the transfers were not a gift but for division of family property purposes that they were. Thus, the value of these shares form part of the net family property.
