The maximum monthly OAS payments to eligible taxpayers in 2023 are as follows¹³:

Receiving the OAS benefit may be deferred for a maximum of five years. The benefit is then increased by 0.6% for each month of deferral, up to a maximum of 36%.

The Old Age Security Benefit Estimator can be used to determine the amount of benefits that could be paid out.

OAS benefits are reduced¹⁸ at the rate of 15% when an individual’s income reaches $86,912 and cease to be paid when income reaches $142,428 ($147,979 as of age 75). The GIS (with non-pensioner spouse), the spousal allowance and the surviving spouse benefit cease to be paid when the beneficiary’s income reaches $50,736 , $39,168 and $28,512 respectively¹⁹.

It is not financially advantageous to defer your OAS to after the age of 70. On the contrary, you could lose benefits.

13The amounts and income thresholds are adjusted quarterly, those for the last quarter, i.e., the months of October,
November and December, were not available at the time of publication. For additional information: Old age securitypayment amounts.
14 The amounts shown are maximums, based on the previous year's income of the spouses; several conditions must
be met to qualify. A GIS supplement is available for people with very low incomes.
15 Single, widowed or divorced pensioner or married pensioner whose spouse is not a pensioner.
16 Married couples (or in a common-law relationship) when both spouses are pensioners.
17 Amount available to low-income taxpayers whose spouse is either a GIS recipient or deceased.
18 The maximum redemption thresholds indicated here are those applicable to the third quarter of 2023. Benefits are generally recovered by means of a withholding mechanism, which eliminates the need for individuals to repay the benefits when filing their tax returns for the year.
19 The OAS and first $5,000 in employment or self-employment income are not considered for the purposes of these limits and a partial exemption of 50% applies to the next $10,000 of such income.

An annual benefit of $400 is offered to seniors 60 years of age or older living in New Brunswick. To be eligible, the person must have received a federal GIS or a federal OAS allowance for the preceding year. A single benefit is paid per couple. However, if the spouses live apart (e.g. if one of them is in a nursing home), both are eligible for the benefit.

Guaranteed Annual Income System – Ontario

The guaranteed annual income system guarantees Ontarians 65 years or older who receive OAS benefits and the GIS²⁰ a minimum income by paying them a monthly benefit of up to $83 ($166 per couple)²¹ based on the total family income. For 2023, benefits are temporarily doubled to $166 ($332 per couple) per month. It is not necessary to apply for this amount.
