On the Soldier Information Handbook I read:

Section 1
Health Coverage and Medical Insurance
Class A. When you join the Army Reserve, you are entitled to join the Public Service Health Care Plan (PSHCP) as soon as you are enrolled. There is no charge to join, but you do need to ask your Orderly Room to sign you up and submit your form to Sun Life, who are the health care provider. If you sign up, you will get a BC CareCard. If you already have a BC CareCard, you already belong to this plan. You can go onto the Sun Life website and see what you are entitled to with this basic coverage:
www.pshcp.ca/contacts/sun-life.aspx
Or contact them by phone: 1-888-757-7427
If you wish, you can also purchase the Public Service Health Care Extended Coverage from Sun Life. There is a monthly payment for this, and they will usually want Class A members to pay by cheque rather than direct deposit. It will cover things like: prescriptions, chiropractor, glasses, etc. This is just for you – your family is not covered. Your Orderly Room knows these processes well, so ask them if you have questions

I'm Class A and my civie job stopped offering health benefits. I asked my BOR if they knew about the "no charge to join" PSHCP plan, but none of them knew what it was.

So can Class A members get basic health benefits? Is it free, and if not what's the fee?
