URGENT! YOU COULD SAVE A LIFE. My friend has lung failure and has financial difficulty. PLEASE HELP.?

So I just found out that my friend has lung failure. He only found out today as well.

His family is poor, he has 6 siblings and needs financial help. He lives in Canada and hes only 16.

He only turned 16 like a week ago. The doctor told him he only has six months left and needs to have surgery. I've told him to tell his doctor about his family struggle with money but he doesn't see the point. He won't tell anyone about it. He doesn't want to talk to people about it and said that no one will care and that no one will help. I told him to tell his school coz they will most likely start fundraising but he reckons no one will care.

I'm really concerned about him. I really want to help but he won't listen to me. I've tried researching organizations that will help but i haven't found much. I don't know much about Canada. I know that there are good people out there that will donate and help. Sadly my friend doesn't believe in this. Are there any organizations out there in Canada that will assist with his financial problem? I really don't know what to do. Who will help him? He needs money for his operation. My friend is really scared, he has no hope and he thinks he's going to die. He won't even go to sleep coz hes scared he'll die in his sleep. What help can he get?

I was thinking about getting the attention of celebrities maybe, but that won't be easy D:

PLEASE HELP MY FRIEND. SPREAD THE WORD. YOU COULD BE A HERO AND SAVE A LIFE!!
