The indexing rate for 2018 in Canada is 1.6%.
The indexing of public service pension plan benefits is governed by two pieces of legislation; the Public Service Superannuation Act (PSSA) and the Supplementary Retirement Benefits Act (SRBA).
Pension increases for retired members and their survivors are calculated each year using Consumer Price Index (CPI) data published by Statistics Canada. In accordance with the SRBA, the increase is based on a comparison of the twelve-month average of the monthly CPI for the year just ended, to the twelve-month average of the monthly CPI for the previous year. The SRBA specifies that the twelve-month period from October 1 to September 30 is to be used to calculate the increase payable the following January. The index used for the calculation is the CPI for Canada for all items (not seasonally adjusted).
