OAS notification letter for seniors

When does CRA typically send the letters out?
What can I do if haven't got a notice (it's not in myCRA account either)...

Old Age Security payment rates are reviewed in January, April, July and October to ensure they reflect cost of living increases, as measured by the Consumer Price Index (CPI).

For example:

monthly payment rates will increase if the cost of living goes up
monthly payment rates will not decrease if the cost of living goes down
Note: Subsequent to the increase in the Consumer Price Index, OAS benefit amounts will increase by 1.3% for the July to September 2021 quarter.
