CanHaem’s leadership includes an Executive Committee comprised of the Chair, Vice-Chair, Secretary and Treasurer, and also up to eleven board members who coordinate the work of the Association. In addition, oversight is provided by our Governance Committee. Much of our work in implementing our strategic plan is delegated to our subcommittees: Education, Nursing, and Peer Review.
