Open Question: I went 117km/h in an 80km/h zone, how much will this affect my insurance?

I got pulled over and got a ticket of about 277 dollars, the cop said i could talk to the prosecutor and he can lower the fine down as well as the demerit points, so if the fine does get lowered and i only went around 29km/h over the speed limit, how much can this affect my insurance rates? Btw, this is my first ticket ever, and im a G2 driver and have been driving for about a year.
