Is there any services that provide birth doula in Toronto?

Good afternoon friends,
Today I am here in search of a birth doula in Toronto for my younger sister. She is two months pregnant now. She is having some health problems such as anemia and depression. She always feels tired or weak and even faints. A mother's depression can also affect the baby too. So, getting proper medication and treatment is important. Her husband is working overseas and her mother-in-law is the only person along with her. She is an old lady, she cannot even look after herself, so how can she look after my sister?
I am living nearby her house, I used to go there when I am free. But it is not possible to be with her all the time. So, we thought that it would be better if she could get a birth doula who provides both mental and physical support during her pregnancy period. Are there any services that provide birth doula?
