To be a bit more technical, there are four types of offences defined in the act: not registering an arrangement, not updating an arrangement, hiding information and obstruction.
Administrative monetary penalties can be imposed for the first three types, but for obstruction, it just becomes an offence. However, a criminal offence can be established for all four types. In that instance, the case is referred to the RCMP and it will be up to the prosecutor and the police to determine exactly whether the offence will be punishable by summary conviction or otherwise. It will be up to the Crown and the police to define it at that stage.
