Hi Asma
Kanthasamy is a leading case in this matter, as it has many similarities. I also have reviewed some relevant court cases here: https://www.settler.ca/english/the-best-interests-of-a-child-bioc-in-canadian-immigration/
Finally, I normally do not make an H&C case about legal precedence. I try to focus on the merits of the case.
I hope this helps.
