FINTRAC is unable to establish a pattern in those reports and prosecute. Instead, when someone is charged with an indictable offence, their name and related entities are searched for STRs. Any financial crimes are then used to create additional charges.
The net result of this, because of lack of digitization and various privacy guarantees, is that it is almost impossible to be charged with financial crimes as a primary offence in Canada.
