Good man. YOU need to start your research. This board is excellent as well as ticketcombat.ca
The goal here is to try to get the charge stayed on the grounds of delay or improper disclosure. You will also likely be offered a reduced fine/points by the crown on the day of the trial.
Read up, then send your disclosure request as soon as possible!
Make sure you ask for the following:
1. Copy of officers notes (including specific details of how and when the speed measuring devise was tested on the day of infraction)
2. Typed version of any hand written notes (with explanations of any abbreviations or short-hand used)
3. Copy of both sides of the officers copy of the ticket (notice of offence)
4. witness will say statements
5. any statements made by the defendant.
6. Make, model, and serial number of speed measuring device (radar, lidar, etc) used, and its owners manual in its entirety.
Keep us posted on any replies you get from the crown. Good luck.
