11. As of 1 January 2019, the fees payable per a plan member pursuant to section 10 shall be indexed on 31 December of each year by multiplying the amount payable before that date by the ratio that the average, for the 12-month period ending on 30 June of the current year, of the average weekly salaries and wages for the Industrial Composite in Canada for each of the months comprised in that period, as published by Statistics Canada pursuant to the Statistics Act (R.S.C. 1985, c. S-19), bears to the average, for the 12-month period ending at the end of June of the year immediately preceding the current year, of the average weekly salaries and wages for the Industrial Composite in Canada for each of the months comprised in that period, as published by Statistics Canada pursuant to the Statistics Act. The result of indexation shall be rounded up to the nearest multiple of $0.05.
The amount thus determined may not be less than the amount that was payable before indexation.
Retraite Québec shall publish in the Gazette officielle du Québec the result of indexation and, if it deems it to be expedient, by way of any other medium.
