I can only speak from an Ontario perspective on that, because it is different from province to province and territory.
In Ontario, the long-term care act is very vague in the level of social work service within the legislation. Basically, there is no specific mandate that long-term care homes have to have a social worker on staff, and in fact, the majority of them don't have a social worker on staff, so they would hire out. They may hire a social service worker as opposed to more highly educated social workers. Many of the psychosocial issues for older adults in long-term care are not properly dealt with.
