I am working in Canada as a Live in caregiver. I also helped my sister find the same job in Canada. There are a lot of conditions/restriction/requirements for caregivers who want to work in Canada.

1. Successful completion of the equivalent of a Canadian high school education. In some countries this may mean you need to have at least 2 years of post secondary education.
2. Six months of full-time training or 12 months of experience paid employment. This employment has to be in a field or occupation related to the job you are seeking as a live-in caregiver.
3. Ability to speak read and understand either English or French.
4. Must have clean criminal record check (In case of overseas nannies, there is necessary to get criminal record check in country of your permanent residence)

Your wife does not have proven childcare or eldercare experience, the caregiver course is not enough.

I also tried to find sponsor for my other relative in Philippines but the visa processing time in the Philippines at least 18-24 month and families do not want to wait.
