dstate,
My opinion is that unlike Drinking and Driving charges, which the 4 cases in the article cover, Part II summary offences like the one you're charged with can be argued to be simpler in nature. These simpler charges wouldn't require the inherent time needs of hiring a lawyer and the process for obtaining disclosure should be shorter.
In your case, depending on the steps you've taken thus far, you should be able to argue an 11(b) successfully.
Things to consider [R. v. Morin is used as the base for these questions]:
How quickly did you file your Notice of Intention to Appear within the 15 day window?
How quickly did you request disclosure [you should do so NOW if you haven't]?
Requesting disclosure is an important step which in itself can cause delays that could be attributed to the Crown. If you were stopped in the GTA area, you can also request disclosure of in-car video as there's a high possibility that your interaction with the officer was recorded. You have full rights to this from a legal standpoint, as it could potentially help you in your case. Also, officer notes should be legible and easily understandable, and the delays in getting this could also be argued against the Crown.
I'd request disclosure three times using the fax method [once every 4-6 weeks until you get it], or in person at the courthouse, and see how that goes. If you do not receive complete disclosure, you have the absolute right to ask for an adjournment on your scheduled court date. This should be argued against the Crown. Wait until 2 months before your court date to see where you stand on disclosure, and then depending on how things are going, you can proceed with an 11(b) application.
Hope this helps. Cheers.
