<HTML>You can make an appeal on the visa refusal decision. I suggest you find a lawyer to file the appeal process for you. There are many lawyers specilizing into the Canadain immigration law.
You can make the official appeal on your own, but chances are you may get rejected again because visa officers are hard to convince, except get a lawyer involve in your case (one person I know had this problem before). If you got rejected again, it is even more difficult to applythe visa again.</HTML>
