Support in native communities

Hi!! I’m not Native, but I have a close friend who is. We’re both highschoolers and he lives on a reservation in Canada while i’m in the US. He has been really struggling with his mental and physical health, I was wondering, are there any help services for natives in Canada? 😕 I’m from the US and I know there are here but I don’t know where to find anything for Canada. This is a broad question I know, but this goes for any kind of help. Second part of my question, if there’s physical abuse going on in a household — is there anything I can do?? I know this is a sensitive topic, but I am very genuinely curious about this. I know there’s been a lot of unjust government intervention when it comes to native families and communities - so I want to be informed. And if there’s nothing I can do, where can I point him so he can get help?? Thank you for your time. ❤️
