Son addicted to gaming

Last weekend, I found out that my son failed in the last semester. I had logged into his college site to pay his spring semester fees and his grades for the previous semester were posted. I was just shocked to see his result. When I asked him about this, he admitted that he stopped going to classes in order to play Baccarat and other sorts of gambling games. I blame myself for his gambling addiction. I let him play countless hours without even telling him to spend more time on studies and with the family. I should have been a strict father. I shouldn't have allowed him to spend money in the way he wants. How can I stop his addiction? I just don't know what to do. Is counseling something that will work? I am considering to get him gambling addiction treatment from Calgary. I want my son to stop this addiction. I am upset and need help. Any advice?
