Question regarding a sibling

[Jatinderbaban]

Hey guys
I have received an ITA for Canadian Experience. I have a biological brother who was adopted by my uncle. We have same biological parents. Our parents name on birth certificate is same. But his legal parents are different than mine.
will I be able to claim him as my brother?
thanks

Generally adoption severs the legal relationship between a person and their parents, and therefore you.
