If you're worried about insurance rates, then any HTA conviction will raise it. A By-law "could" raise it, but it probably won't.
You must resolve your disclosure issues with the prosecutor prior to discussing plea-deals. It's important to not accept any plea-deals until you receive full disclosure, and this is the officer's notes. His notes are essentially what the prosecution is going to use against you. If the officer is present, it's important that you review the notes with him so that you understand it. Officers uses short-form writing, and abbreviations that the general person may not understand.
Keep in mind, there's the possibility the officer failed to take notes on that day, because of an emergency. Possibility the officer doesn't show up to your trial. Possibility the officer forgets his notes at your trial.
All of the above may result in the prosecutor withdrawing the charge especially if it's in the City of Toronto, where they're pretty backed up.
@Radar Identified is correct, a lot of the items in the disclosure request are unnecessary & over-the-top. If the prosecutor wanted, they can make you explain in front of the justice of peace, why you want each individual item. How each item is relevant to your charge? Something to the effect of who's criminal record do you want?
Now you can say that you're self-represented and that you found this form online, and used it. The courts may initially bark at you but they'll understand why you used it.
Lets say the officer and his notes are present. You can still get an adjournment (new trial date) to review the disclosure. This also gives you one more opportunity for an 'officer no-show'.
