52.0.1. If rights of an employee under the agreement referred to in section 48 have, by one or more transactions between persons not dealing at arm’s length, become vested in a particular person who transfers or disposes of the rights to a particular qualifying person (or a qualifying person with which the particular qualifying person is not dealing at arm’s length) with which the particular person is not dealing at arm’s length, the employee is deemed, subject to the second paragraph, to receive, because of the employee’s office or employment, in the taxation year in which the particular person made the transfer or disposition, a benefit equal to the amount by which the value of the consideration for the transfer or disposition exceeds the amount paid by the employee to acquire those rights.
Where the employee was deceased at the time the particular person transferred or disposed of the employee’s rights, the benefit is deemed to have been received by the particular person, in the taxation year in which the particular person transferred or disposed of the employee’s rights, as income from the duties of an office or employment performed by the particular person in that year in the country in which the employee primarily performed the duties of the employee’s office or employment.
