What determines the amount of old age pension in Canada?

2 min read

For the period of July to September 2025, the maximum monthly Old Age Security (OAS) payment is up to $734.95 for those aged 65-74 and $808.45 for those 75 or older. To find out what determines the amount of old age pension in Canada for your specific situation, it is crucial to understand the multiple factors involved, including residency, deferral age, and income.

Quick Summary

The amount of old age pension in Canada depends on factors like years of residency after age 18, the age benefits are first collected, and annual net income. Supplementary benefits like the Guaranteed Income Supplement are determined by income and marital status. Quarterly adjustments are also made based on inflation.

Key Points

  • Residency History: OAS amount depends on years of Canadian residency after age 18.

  • Start Age: Delaying OAS past 65 increases monthly benefit.

  • Income and Clawback: High income can reduce OAS through a recovery tax.

  • Inflation Adjustments: OAS and GIS amounts are adjusted quarterly based on the CPI.

  • Guaranteed Income Supplement: Low-income seniors receiving OAS may qualify for the non-taxable GIS based on income and marital status.

  • Automatic vs. Manual Application: Some seniors are automatically enrolled, others must apply.

  • Age 75 Increase: Seniors aged 75 and over receive a 10% increase to maximum OAS.

Core factors influencing your Old Age Security (OAS)

The main component of Canada's old age pension is the Old Age Security (OAS) benefit, which is funded by general tax revenues. The amount you receive is influenced by several key factors.

Length of Canadian residency

Your years of residency in Canada after age 18 significantly impact your OAS amount. A full pension requires at least 40 years of residency. A partial pension may be available if you have between 10 and 40 years of residency, calculated as 1/40th of the full amount for each year in Canada after age 18. Residency rules differ if you live outside Canada.

Age at which you start collecting

You can start OAS at age 65, but delaying payments can increase your benefit. Each month of delay after age 65 can increase your pension by 0.6%, up to a 36% maximum at age 70. Those 75 and older receive a 10% increase.

Income and the OAS recovery tax

Your previous year's net income can lead to an OAS reduction known as the "clawback". For income above a certain threshold, your OAS is reduced. High earners may see their benefit eliminated.

Additional benefits: Guaranteed Income Supplement (GIS)

Low-income seniors receiving OAS may qualify for the non-taxable Guaranteed Income Supplement (GIS). Eligibility and the amount are based on marital status and previous year's income, excluding OAS. Lower income generally means a higher GIS benefit.

The role of inflation

OAS and GIS amounts are reviewed and adjusted quarterly based on the Consumer Price Index (CPI) to align with the cost of living. Benefits increase with the cost of living but do not decrease if it falls.

Comparison of OAS and GIS factors

Here is a comparison of the factors that determine OAS and GIS benefits:

Factor Old Age Security (OAS) Guaranteed Income Supplement (GIS)
Funding Source Funded by general government tax revenues. Also funded by general government revenues.
Eligibility Age 65+ with at least 10 years of Canadian residency after age 18. Must be receiving OAS and have an income below a set threshold.
Calculation Basis Years of residency, age at start, and annual net income for clawback. Annual income and marital status.
Tax Status Considered taxable income. Non-taxable income.
Indexing Adjusted quarterly based on the Consumer Price Index (CPI). Also adjusted quarterly based on the CPI.
Delay Option Can be delayed up to age 70 for higher payments. Cannot be received while delaying OAS.

Conclusion

The amount of your Canadian old age pension is influenced by residency history, age when benefits start, and income. The base OAS amount depends on years of residency and may be reduced for high earners. GIS offers additional non-taxable support for low-income seniors. Both are adjusted quarterly for inflation.
