Membership to CARMA must be acquired either through the Canadian Institute of Mining,  Metallurgy and Petroleum (CIM) or Canadian Geotechnical Society (CGS).  Members of the CGS that select Rock Mechanics as their primary discipline will automatically become members of CARMA and the the International Society for Rock Mechanics (ISRM).  Members of CIM that choose  as a sub-discipline the Society for Rock Engineering, and pay an additional fee, will become members of CARMA and ISRM.  CARMA members receive all the benefits of their parent organizations (CGS or CIM) as well as resources available to ISRM members.
