Moving out on my own.?

As of right now i am 15 years old and i still have a 2 more years of high school left, I plan on moving to B.C ( i live in Alberta), once i am done school ( the summer i graduate), I know i Want to go to SUF or UBC but he thing is i don't know what to do when i get there or how am going to do it. There is also one more thing how do i tell my Father who really does not want me to leave at all and thinks its a dumb idea and should stay and got to the UofA,
