As Social Security nears a funding crisis, the political pressure to fix the system is mounting. The Social Security Trust Fund, which is used to help pay benefits, is projected to be depleted between 2033-2035, at which point benefits would be paid only from ongoing payroll taxes, resulting in an automatic benefit cut of roughly 20% unless reforms are enacted.
In contrast, Canada’s retirement income system, made up of the Canada Pension Plan (CPP) and Old Age Security (OAS), faces much less political scrutiny, even though it’s structured quite differently. This contrast offers a compelling lens to examine what the U.S. might learn from its northern neighbor and what mix of reforms might be both fair and financially sustainable for future generations.
Overview: U.S. vs. Canada Retirement Systems
United States: Social Security
- Funded by payroll taxes: 12.4% of wages, split evenly between employer and employee (6.2% each)
- Benefits based on a worker’s top 35 earning years
- Trust Fund invested solely in U.S. Treasury Securities
- Full Retirement Age (FRA): gradually increasing to 67
Canada: CPP and OAS
- CPP: A contributory pension based on lifetime earnings and contributions
- Contribution rate: 5.95% from both employee and employer (total 11.9%). Beginning in 2024, an additional maximum pensionable earnings (second higher ceiling) is introduced. Employees and employers are required to make a second additional CPP contribution (CPP2) on these earnings, beginning at the first earnings ceiling and going up to the second earnings ceiling, at a rate of 4.0%.
- Max pensionable earnings (YMPE): $71,300 CAD (2025)
- Managed by the CPP Investment Board (CPPIB), invested globally in stocks, bonds, real estate, and infrastructure
- OAS: A universal benefit funded from general tax revenue
- Begins at age 65
- Subject to means testing through a clawback starting at $93,454 and fully phased out at $151,668 CAD
Funding Models and Investment Strategies
One of the most fundamental differences lies in how the two countries manage their retirement trust funds.
- Social Security Trust Fund: Invests exclusively in U.S. Treasury securities. While considered safe, these assets typically yield lower returns than marketable securities.
- CPP Fund: Managed by a professional investment board (CPPIB), which holds a diversified portfolio of global stocks, bonds, private equity, infrastructure, and real estate.
Over time, the investment strategy used by CPPIB has delivered higher long-term returns. If Social Security had adopted a similar diversified investment model decades ago, the Trust Fund might be in a far stronger position today. Furthermore, investing SS assets in marketable securities might have also influenced U.S. capital markets by boosting equity demand (raising prices) and reducing bond demand (raising yields), with complex implications for growth and interest rates.
However, hindsight is not a policy. The question remains: what should be done moving forward?
Current Proposals to Fix Social Security
Several proposals are on the table, each with trade-offs:
- Raise the Full Retirement Age (FRA)
- Would reduce lifetime benefits for future retirees
- Critics argue it disproportionately impacts manual laborers, young people, and lower-income workers
- Increase or Eliminate the FICA Cap
- Currently set at $176,100 (2025)
- Lifting it would subject more earnings to the 12.4% payroll tax
- Progressive in nature but could face resistance from high earners and business owners
- Raise the FICA Tax Rate
- Increasing from 6.2% per side to 7% or more could close much of the funding gap
- A broad-based approach, but politically difficult during inflationary times
- Introduce Means Testing for Benefits
- Would reduce or eliminate benefits for wealthy retirees
- Aligns with Canadian-style OAS clawback
- Could reduce public support by weakening the universality of the program
- Reduce Future Benefits
- Would disproportionately affect younger generations
- Could be phased in gradually, but still controversial
Key Differences in Design Philosophy
| Feature | U.S. Social Security | Canadian CPP | Canadian OAS |
| Tax Rate | 6.2% (employee only) | 5.95% (employee only) | Funded via general revenue |
| Earnings Cap | $176,200 USD | $71,300 CAD | N/A |
| Investment Strategy | U.S. Treasuries | Marketable securities | N/A |
| Universality | Based on contributions | Based on contributions | Universal with clawback |
| Means Testing | No | No | Yes (clawback begins at $93,454 CAD) |
Why CPP and OAS Aren’t a Political Football
Unlike Social Security, reforming CPP or OAS doesn’t dominate Canadian election cycles. Why?
- CPP underwent major reforms in the late 1990s to ensure long-term sustainability—raising contribution rates and establishing the CPPIB to manage investments prudently.
- Canadians view CPP and OAS as part of a broader mix of income sources in retirement (including RRSPs and TFSAs), not as the sole source of support.
- The means-tested nature of OAS introduces a built-in mechanism for cost control.
In contrast, Americans often see Social Security as the cornerstone of retirement income. Any proposal to reduce benefits or change eligibility is viewed as a breach of trust, particularly by younger generations who worry they’ll pay into a system that won’t support them in retirement.
What’s the Right Fix for Social Security?
There’s no perfect answer, but a thoughtful combination of measures could help restore solvency while preserving fairness:
- Gradually raise the earnings cap to make high earners contribute more without immediately eliminating the cap entirely.
- Index the FRA to life expectancy, but consider occupation and income-based adjustments to protect lower-income and physically demanding jobs.
- Phase in modest FICA increases, split between workers and employers.
- Introduce a soft means test for very high earners, similar to the OAS clawback, while maintaining core universality.
- Allow a portion of future contributions to be invested in a diversified portfolio, professionally managed by an independent board—similar to the CPPIB model.
Social Security is not beyond saving, but it requires political courage and generational fairness. Canada’s model, with lower maximum contributions, higher investment returns, and some means testing, offers useful insights. However, simply copying it isn’t viable; the U.S. must craft a uniquely American solution that honors commitments, protects the vulnerable, and adapts to demographic and fiscal realities.
As voters and policymakers grapple with what comes next, the guiding question should be: What kind of retirement system do we want to leave our grandchildren? A sustainable one, funded fairly and invested wisely, should be a goal both parties can get behind.
