In Canada, Lots of people use the "live in caregiver" program, which allows for foreign nannies and senior care workers (often from Philippines) to come to canada as temporary workers for 2 years, then apply for permanent status (which takes another 4+ years),
The candidates are fully trained, experienced and screened for this work before coming to Canada, even when sponsored by extended family, they have to show passing classes and in-country experience first.
This means that there are a lot of qualified, experienced care workers in our cities that have exceeded the 2 year minimum, and can have an open work permit to work for anyone, yet have trouble with traditional hiring situations and would like to make more $$s.
So -- when I put an ad in the local paper, I received 30 replies, interviewed 20, and was blown away by the quality of candidates, all with references. (mine was a FT position near transit, but still...)
Look for referral agency or others, and ask around.
