I feel a bit daft. Here I have been muttering around about the need for more training for dementia care and I just found this site which offers all kinds of resources and specializes in training aides at Long term care institutions. There is a whack of stuff there that we can use as home caregivers or to help train our people who are helping us, whether paid or family-and-friends. They have an extensive library http://www.crisisprevention.com/Resources/Article-Library/Dementia-Care-Specialists-Articles and also a lovely little e-book on communication tips, which I think is a good first step.
On top of this new discovery, I have also found out that the BC government has a registry site for care workers, the British Columbia Care Aide and Community Health Worker Registry, (http://www.cachwr.bc.ca/Home.aspx)
which requires employers to report abuses, and to hire only registered health care workers. Who knew!
