To clarify, yes, Canadians are volunteering as individuals with various aid organizations like MSF, but there are no Canadians sent by Ottawa to West Africa for direct patient care.

To be fair, even the large American military contingent sent over are not there to provide direct patient care, but to provide logistical support for civilian workers. And like Canada, the US military is providing laboratory services but they will have no direct patient contact. However, about 70 volunteers from the uniformed members of the US Public Health Service are there to staff a center in Monrovia built by the US military and reserved for infected healthcare workers (which I'm not sure is up and running yet).
