Speeding ticket question

I received a ticket not too long ago where the cops claimed I did 120 on Decarie. Well I know I didn't do 120 or even 110, there were too many cars for that anyways. He wrote that he got the speed from following me but he only came up behind me when I was on the 720 ready to get off at Atwater but he wrote 15south. Anyways, what my real question is is if 5 points for 120 in a 70 is right or if I had to be going 121 in a 70 zone to be 5 points. Either way I wasn't going 120 and I have a witness to comply with my statement. Does anyone have the km/h over compared to how many points it is?
Thanks a lot and sorry for the long post.

Check that, sorry I did not find it in english:

Infractions Nombre de points



• Excès de 11 à 20 km/h - 1 pt

• Excès de 21 à 30 km/h - 2 pts

• Excès de 31 à 45 km/h - 3 pts

• Excès de 46 à 60 km/h - 5 pts

• Excès de 61 à 80 km/h - 7 pts

• Excès de 81 à 100 km/h - 9 pts

• Excès de 101 à 120 km/h - 12 pts

• Excès de 121 km/h ou plus - 15 pts et plus

There's no difference between going 120 or 121 in a 70 zone. It's still 5 points and the fine is the same too.

wow you guys are lucky.....

in ontario it's 50 over and you lose your liscence....
