Section 407 [2] provides that an individual is not excused from giving information or evidence under section 406 [2] on the ground that it could incriminate the individual or expose the individual to a penalty.
However, such information is not admissible against the individual except in proceedings that relate to the MRCA brought under sections 137.1 and 137.2 of the Criminal Code.
