Critics have argued that organized crime has been allowed to flourish in Canadian cities such as Toronto due to the difficulty and cost of prosecuting organized crime cases compared with individual cases, and the flexible minimum sentencing and the double time served stipulations that the judicial system utilizes to unburden the penal system. Today, Toronto has become a center for a wide array of organized and transnational criminal activities, including the counterfeiting of currency, bank cards, and digital entertainment products, together with telemarketing fraud and the production of marijuana and synthetic drugs. Toronto also has a comparable rate of car theft to various U.S. cities, although this is lower than in some other Canadian cities. Much of this has been attributed to organized crime, with stolen vehicles ending up being shipped overseas for sale.
