ARM Organization

What is ARM?

In 1996, the Ontario Secondary School Teachers' Federation (OSSTF) established a new type of membership specifically for Active Retired Members (ARM). For a $50 annual fee, ARM allows retired members to remain actively involved politically and socially with their colleagues. The fee is charged by OSSTF each January. If you join ARM mid-year, the fee is waived until the following January.


Why join ARM?

Plan Information

How to join ARM?

To join ARM, simply complete an online application form or contact the OSSTF Provincial Office at 1-800-267-7867.

If you choose to purchase an ARM health plan, you are automatically enrolled in the ARM organization. The ARM Organization Fee is waived for the rest of the calendar year in which you retire (first enrol in an ARM health plan). The $50 annual fee is then deducted annually with your January health plan premium payment.
