Inflation refers to the increase in the prices of goods and services over time. Pension plans can help offset the negative impact of inflation by providing inflation protection, in the form of periodic increases to the amount of a pension payment. These increases help reduce the erosion of buying power caused by inflation.
In the CAAT Plan, when members retire, their initial pension payment is called the "lifetime pension." Inflation protection, when it is granted, is added to the lifetime pension each year that the Consumer Price Index (CPI), a widely-used measure of inflation in Canada, has increased. The new amount is the new lifetime pension. In other words, inflation protection is cumulative. Once inflation protection has been paid, it is a permanent addition to your retirement income.
