25. An employee who has held casual employment defined by regulation under paragraph 14 of section 134 of the Act respecting the Government and Public Employees Retirement Plan (chapter R-10) is entitled to be credited with the service earned while in casual employment between 30 June 1973 and 1 January 1988 with an agency or body contemplated by the Government and Public Employees Retirement Plan or with an agency or body which, in the opinion of the Commission, would have been contemplated by the plan had it not ceased to exist. For the purposes of this paragraph, any period during which the employee is eligible for salary insurance benefits is counted as a period of service.
The employee must, to be credited with that service, pay to the Commission an amount equal to the contributions he would have been required to pay if he had been a member of the Government and Public Employees Retirement Plan, with interest, compounded annually, at the rates determined, for each period, under the Act respecting the Government and Public Employees Retirement Plan. Interest shall run from the midpoint of each year until the date of receipt of the application. If the employee applies to have only part of that service credited, the most recent service will be credited first. Any pension credit that may have been granted under the Act respecting the Government and Public Employees Retirement Plan or the Act respecting the Pension Plan of Certain Teachers (chapter R-9.1) in respect of such service is cancelled and the sums paid in respect thereof are refunded with interest. The years and parts of a year credited in respect of such service pursuant to section 23 shall be cancelled.
Any service redeemed under this section shall be credited under this plan to the extent determined under section 39.
