The Ontario Teachers' Pension Plan was established in 1990 through the merger of the Ontario Teachers' Superannuation Fund and the plan for teachers of the former Ontario Board of Education.

As of 2021, the Ontario Teachers' Pension Plan has approximately 329,000 active and retired members.

In Ontario, the Ontario Teachers' Pension Plan is generally protected from garnishment by creditors. However, there are exceptions for certain types of debts, such as family support obligations or arrears owed to the government. It is best to seek legal advice for specific situations involving garnishment of pension funds.

The amount of a teacher's pension each month will vary based on factors such as years of service, salary level, and pension plan specific details. Teachers typically receive a percentage of their final average salary as their pension benefit. It is recommended to check with the respective pension plan or retirement system for specific details.
