452. Where, by reason of one and the same employment injury, a person is entitled to both a benefit under this Act and a benefit under an Act other than an Act of the Parliament of Québec, he shall elect one of them and notify the Commission of his election within six months of the industrial accident or of the date when it is medically established and brought to the attention of the worker that he has contracted an occupational disease or, where such is the case, of the death as a result of the employment injury.
If the person fails to make the election, he is presumed to waive any benefit under this Act.
