Balancing plan assets and the cost of future pensions is an ongoing objective for the two sponsors of the Ontario Teachers' Pension Plan: Ontario Teachers' Federation (OTF) and the Ontario government.

When making decisions on behalf of all beneficiaries, the plan's management and sponsors consider the impact of ever-changing demographic and economic factors and risks. The table below shows changes in key funding variables since the pension plan's inception in 1990.

Funding Variables Comparison 2020 1990
Average retirement age 59 58
Average starting pension $47,500 $29,000
Average contributory years at retirement 26 29
Expected years on pension 32 25
Number of pensioners aged 100 or more 147 13
Ratio of active teachers to pensioners 1.2 to 1 4 to 1
Average contribution rate 11.0% 8.0%


Key funding considerations:

The plan has identified four main funding risks – longevity, interest rates, inflation and asset volatility – and seeks to manage intergenerational equity given these risks.


Teachers in Ontario live longer than the general Canadian population and their life expectancy continues to increase. It costs more to pay lifetime pensions when members live longer. At the same time, members are contributing to the plan for fewer years than in the 1990s, and their retirement periods are longer. Given the longevity of the plan members, Ontario Teachers’ uses plan-specific mortality tables and custom two-dimensional mortality improvement scales which are regularly reviewed and updated as warranted. The tables and scales were recently updated and have been used in the January 1, 2020 valuation.


The plan seeks to provide retired members with annual pension increases to offset the impact of an increased cost of living (inflation). Inflation that is higher than assumed in the valuation increases the plan's liabilities, given the plan's inflation protection feature, while inflation that is lower than assumed reduces the plan's liabilities. The annual increase received by retirees on the portion of their pensions earned after 2009 is conditional on the plan's funded status.

Asset volatility

2019 marked both the longest U.S. economic recovery and the longest bull market in equities on record. The equity market upswing persisted even as economic growth slowed and corporate earnings disappointed, which suggests an elevated risk of a price correction if underlying fundamentals don’t recover sufficiently to justify the high market valuations. A material drop in asset prices would negatively impact asset values. Currency volatility also has an impact on assets. Volatile asset markets can present opportunities for long-term investors such as Ontario Teachers’, but they can also lead to investment losses that affect the plan’s funded status.

Intergenerational equity

The design and implementation of an innovative funding risk mitigant, conditional inflation protection (CIP), adds flexibility to the plan and promotes intergenerational equity. It recognizes and virtually neutralizes the impact of the changing ratio of active to retired plan members on the plan's funded status.

The plan sponsors prudently and proactively introduced CIP in 2008, recognizing that if significant investment losses or a funding shortfall occurred, an increase in contribution rates alone was unlikely to be sufficient, and increases would be borne solely by active plan members.

CIP allows flexibility in the amount of inflation increase provided to pensioners for benefits earned after 2009. The level of increase is a sponsor decision and is conditional based on the funded status of the plan. Pension credit that members earned before 2010 remains fully indexed to inflation. There are three levels of inflation protection for members, which are based on when pension credit was earned: before 2010, during 2010 to 2013, and after 2013.

When pension credit
was earned
Inflation protection
What this means
for members
Before 2010 100% This portion of a member's pension will keep pace
with annual increases in the Consumer Price Index (CPI).
During 2010–2013 50% to 100% This portion of a member's pension will receive at least 50%
and up to 100% of the annual increase in the CPI, depending on the plan's funded status.
After 2013 0% to 100% This portion of a member's pension will receive from 0%
to 100% of the annual increase in the CPI, depending on the plan's funded status.


CIP is an effective lever for mitigating funding risks while also promoting intergenerational equity because, over time, as more active members retire, the risk of significant investment losses or a funding shortfall is distributed more broadly among the membership – that is, risk is shared by more retired members.

CIP is becoming more powerful over time. The proportion of service that members have earned after 2009 continues to grow, while the proportion of service earned before 2010 (which is fully indexed to inflation) is in decline. These trends mean that, eventually, all pension benefits will be subject to CIP and active and retired plan members will both share the risk of a loss.

Over the next 15 years, the percentage of the plan’s total liability that is subject to CIP will increase from 51% to 77%. As CIP applies to more of the plan’s total liability, it will be able to absorb a greater loss, making it an extremely effective risk management tool.

  1990 2020 2030
Increase in contributions required for 10% loss in assets 1.9% 5.4% 5.7%
Decrease in level of CIP required for 10% loss in assets n/a 29% 20%
Asset loss capable of being absorbed by fully invoked CIP n/a $47B $96B


As an example, a 10% asset loss in 2029 could be absorbed by lowering inflation protection increases for benefits earned after 2009 from 100% to 79%. As another example, in the most extreme case, if CIP levels were lowered to 50% on benefits earned during 2010–2013 and to 0% on benefits earned after 2013, this funding lever would be powerful enough to absorb a 2029 asset loss of $86 billion.
