15. Duty to surrender certificate on cancellation of policy

Where a certificate of insurance has been issued under section 4(4) to the person by whom a policy has been effected and the policy is cancelled by mutual consent or by virtue of any provision in the policy, the person to whom the certificate was issued shall, within 7 days from the taking effect of the cancellation, surrender the certificate to the insurer or, if it has been lost or destroyed, make a statutory declaration to that effect, and if he fails to do so he is guilty of an offence.
