15. If a workman receiving a weekly or other periodical payment under this act ceases to reside in Québec he shall not thereafter be entitled to receive any such payment unless the expert certifies that the disability resulting from the injury to such workman is likely to be of a permanent nature.
If the expert so certifies, the Commission may order that the workman shall be paid quarterly the amount of the weekly or other periodical payments accruing due, if he proves, in such manner as may be prescribed by the regulations, his identity and the continuance of the disability in respect of which compensation is payable.
