Mental, financial and physical torcher by inlaws an d family

Hi, I am 29 years old and married in 2015. Me and my husband is permanent resident of canada .My baby is 6 months old. During my baby’s birth my inlaws came to canada and stay with me and my husband for 3 months. They torcher me badly and ask for money after my baby’s birth. My mother inlaw stopped giving me food at my own house and all of them were so abusive with me. My husband support them and torchered me. My husband bought a condo apartment in his name only and started forcing me to ask for money from my parents in india. I refused to do so he And his family started doing torcher to me. They took my phone, they took my baby and gave me only during breastfeeding they gave me 4 chapatis and a bowl of veggie for whole day. They don’t allow me to enter kitchen becuase as per tradition or myth i was impure after giving birth for 3-4 months. When my inlaws left for india my husband left me alone with my 3 month old newborn. I am currently on matleave and parents don’t have visa. My husband served me a divorce Notice, i have zero knowledge of all legal process and don’t have any idea how to start. In india during marriage my parents gave gold and property to me as a gift, but I can’t go to india without my child. He is just 6 month old, I don’t have his passport and also my husband filed divorce and demanded my sons custody. Is there any way to go india or file dowry case from Canada without going to india to get justice for me and my child.
