The federal or provincial government can put in minimum and maximum fines in regard to any contravention of any law or act. The judiciary, which is a separate branch of government, can interpret that infraction as it applies to a law, then issue a fine relevant to previous case law or to other fines that have been given out, respectively.
To say the provincial minister failed to raise a fine, where applicable, is not the way the real world works. The provincial minister of any department does not interfere with a judge or judicial system, or suggest to the Attorney General what a fine should be. We can bring in a maximum and a minimum, but it's up to the judicial system and the judge hearing the case to determine what the level of fine should be, according to the infraction.
