I'm close to age 70. I am working, and because of my high income, do not receive an old-age pension. What will I be rights upon retiring at age 70?

From your retirement you will be entitled to an old-age pension.
At age 70, there is no longer any income test.
Each year of insurance beyond 9 years, entitles to a seniority supplement of 2% of basic old-age pension rate. However, the amount of the supplement is capped at 50% of the basic pension.
You will also be entitled to a pension deferral supplement.
Rate of pension deferral supplement – 5% of the pension, for each year ineligibility for old-age pension due to higher work income than allowed. The supplement due to you is 15% against the three years you have postponed your retirement (from age 67 to 70).
