You still have options:
1. To find somebody from your region that is already in Canada and is willing to do such work. Just be aware, you can list conditions like knowledge of a specific language or knowledge to cook specific type of food. But you cannot request for specific nationality, sex or religion.
2. Second option would be a live in caregiver. In that case you need to inform yourself more about options and what are the obstacles to get one. Also be aware, that since the option for PR for this stream was scrapped (they would not have enough time to apply until 2019), and so far nothing viable was offered, that might impact the choice (it would be less appealing).
good luck
