Canadian Chess, Eh

Today's puzzle is a little more difficult! Black has a huge material advantage and White's king is threatened. On the other hand, Black's pieces are poorly placed and his own king is also under threat.

What is White's best move, and does it result in a win, draw or loss for White?
