Currently, the Criminal Code has two offences that are charged in these circumstances for match-fixing that is identified. Those offences typically are cheating at play, which is a potential one, but more commonly, fraud, which is under subsection 380(1) of the Criminal Code.
Those offences have been successfully prosecuted, including recently a case that went to the Supreme Court, in 2015: the Queen v. Riesberry. Therefore, we have offences in the Criminal Code that can combat this activity. Of course, there are other issues that have to do with detection.
