Where a person is not a beneficiary, but it affiliated with a beneficiary with a majority interest in a trust, is that person also included in the definition of "majority-interest beneficiary"? CRA stated (TaxInterpretations translation):
A person (other than a trust [later referencing s. 251.1(4)(d)(iii)]) which does not have an interest qua beneficiary in the income nor an interest qua beneficiary in the capital of a trust could be a majority interest beneficiary in certain cases. This is the case if such person is affiliated with a person or persons who have interests qua beneficiary in the income of the trust having a fair market value exceeding 50% of the fair market value of all the interests qua beneficiary in the income of the trust or who have interests qua beneficiary in the capital of the trust having a fair market value exceeding 50% of the fair market value of all the interests qua beneficiary in the capital.
The Explanatory Notes example (re Philip and Muriel) on s. 251.1(3) confirms this interpretation.
