22. An employee who, on 31 December 1991, was a member of the Civil Service Superannuation Plan, is not a pensioner under that pension plan, and held employment referred to in Schedule III to the Act respecting the Civil Service Superannuation Plan (chapter R-12) for one or more periods totalling not less than 5 years or employment referred to in that Schedule while the employee held the employment, is entitled, from that date, to have 10 years added to the number of years of service credited to the employee under that pension plan and transferred to the plan in accordance with section 139 of the Act or section 98 of the Act respecting the Government and Public Employees Retirement Plan (chapter R-10).
Where the employee held such employment for one or more periods totalling less than 5 years on 31 December 1991, the employee is entitled, from that date, to have added the number of years or parts of a year of service obtained by multiplying 10 years by the fraction that the number of years or parts of a year during which the employee held such employment up to that date is of 5 years.
The provisions of the Civil Service Superannuation Plan apply in respect of the years of service added under the first and second paragraphs. However, the years of service are taken into account, subject to section 5, only for the purpose of computing the total pension and may not enable an employee to have more than 35 years of service credited for the purpose of computing total pension.
