Since July 2022 the OAS pension is permanently 10% higher for pensioners 75 and over:[1] $838.75 a month against $762.50 for ages 65–74 in the October–December 2026 quarter.[2] The increase starts in the month after the month of the 75th birthday.[3] Like the deferral increase, it is left out of the pension used for the Guaranteed Income Supplement, so it does not reduce that benefit.[4]
What the engine does
- Pays the 65–74 amount until the month after the 75th birthday, then the 10% higher one, whether the pension started at 65 or was deferred.[3]
- The plan asks for a birth year, not a birthday, and takes every birthday as January 1, so the increase starts in February of the year the person turns 75. Who the plan is about explains that assumption.
What it deliberately does not
The recovery-tax upper limit is also higher at 75+; the clawback formula is unchanged and simply recovers more before it exhausts the larger pension; see the OAS recovery tax.
