Anyway, were you ticketed under section 182(2) of the HTA for "Disobey Sign"? Or was it a different offence?
With a clean driving record, you might have a chance of getting a reduced charge in a plea-bargain deal. The Prosecutor may offer you a municipal by-law infraction, depending on what kind of mood he/she is in. The advantage to that is it won't appear on your driving record. The officer may not show up, or it may take too long for it to go to trial (with the court in Scarborough that's usually the case 40% of the time). First thing is to download a Notice of Intent to Appear from the City of Toronto website (look for the courts section) and pick option 3 on the ticket. On the Notice, check that you want to challenge the officer's evidence. Then you wait for a trial date. That's just to get started... after you get a trial date you can file for disclosure of the evidence against you, etc.
These no-turning by-laws are stupid. They don't make the roads any safer. Besides, enforcing a no-turning sign? Sheesh, the intersection of Vic Park and Lawrence has about twenty HTA offences going on every minute...
