Laws that justly cover this have been on the books in Canada for 40 years as far as I know, probably longer. As it is presented in that article, its a circular argument. A gaming house obviously finances organized crime because it is organized crime. You can't commit these crimes without being organized. If Crown is able to prove that the bookies are using the proceeds to subsidize, murder, armed robbery or terrorism then the Crown can charge the bookie with conspiracy to commit those crimes.
Charge the Bookies with bookmaking and the Murderers with murder, and if a bookmaker conspires to murder charge him with conspiracy to murder. Otherwise it is simply guilt by association.
Obviously this announcement is a publicity stunt. If I were still in Canada I would write my MP and ask him to concentrate on real problems and not to spin his wheels on this nonsense.
