Cost of Living Adjustment for Your Pension

Starting January 2023, your pension will increase by 6.3%. The annual cost of living adjustment (COLA) is applied to all pensioners, survivor pensions and to the deferred pensions of former and divested members.

Every January, pensions are adjusted for the increase in the cost of living, as measured by the Consumer Price Index (CPI), reported by Statistics Canada. This helps to protect your pension against the impact of inflation and to ensure it does not lose value over time.

OPTrust's annual COLA is calculated based on the change in the average monthly CPI between October and September for the previous two years. For example, the 2023 increase was calculated as follows:

Annual annual cost of living adjustment

The maximum increase in any single year is 8%. Any increase above this level is carried forward, and applied in the next year when the adjustment is less than 8%.

The Consumer Price Index (CPI) is a measure produced by Statistics Canada that reflects the cost of a weighted basket of goods and services that are typically purchased by Canadian consumers every month. The CPI is widely used as an indicator of the change in the general level of consumer prices and the rate of inflation.

The COLA feature is designed to protect the purchasing power of your pension during your lifetime. For example, a pensioner who started receiving their pension in January 1995, with an annual pension of $20,000 will receive $34,668 from OPTrust in 2023 - a 73% increase over a 28-year period.

Since the Plan’s inception, COLA has averaged 2.0% per year.

To find out how much your pension will increase in 2023, view your Pension Information Change Statement available through secure Online Services in early January before the paper copy is mailed to your home a few weeks later.

If you retired in 2022, your COLA is pro-rated for the length of time you received a pension. For example, if you retired in June 2022, your pro-rated COLA is calculated by the number of months you received a pension, divided by 12, times the 2023 increase.

In January 2023, your pension would increase by 3.15% to reflect the cost of living for six months. In following years the full COLA will be applied to your pension and will not be pro-rated..
