Can officers choose the amount of the set fine on a speeding ticket?

I was served with a $295.00 total amount payable speeding ticket for going 130 km/h in a 90 km/h zone. I was stopped by the OPP and was given this ticket. Has anybody gotten 40 over tickets and have received a lower fine? I know that the fines are based on how much over the limit the driver was going, but do they have the right to choose the amount on the ticket?
