I am about to start the same process too, transfer my helper to work for my mom in canada. My only worry is that my helper is yanyan, not sure if canadian government will grant her a visa.
Are you thinking of applying your maid to work in Canada? From what I know you can go thru agent too, they normally don't charge the employee much but they will charge the maid around 20K HKD.
From the research that I have done it seems caregiver job in Canada only requires 12 years of education, i.e. secondary diploma.
Don't worry so much though, as you can't control how they think. My yanyan used to mention to me her friends in Taiwan and Korea made more money, but she's still with us after 6 years ;)
