Some caveats regarding the disclosure package:
1) Do not use the disclosure request form that the prosecutors are "nice enough" to hand out. Those basically let the Crown decide what you need for your disclosure package. This page
http://ticketcombat.com/step4/disclosurehow.php has a link to a very nice disclosure request form. I downloaded it it, took out the logo and modified the list of items to suit the particulars of my case.
2) While you should be nice enough to include some information that appears on your ticket/notice of trial (like when the court date is, which courtroom etc etc), do not include your phone number and make sure you modify your fax machine's settings not to include your phone number. That prevents the Crown from claiming "we called him to tell him that the disclosure package is ready, but he never came to pick it up." By the way, if the Crown complains that you did not include a phone number, your response (to the JP) should be "Your Worship, I was going through a transitional period with my telecom services [sob story about a VoIP switch (in my case it's always true because I tweak my VoIP accounts all the time lol)] so I did not have a reliable telephone service, but I am sure that the Crown had heard of Canada Post and its ability to send me a pickup notice with them. I heard that they are even certified to ship restricted firearms, so a notice should not be a security issue."
3) Keep your fax receipts and make sure that your fax machine's time settings are correct. Printing out your outgoing call logs is very helpful if you're with a reputable VoIP provider. When going to court, make sure you print 4 copies of each document you're submitting (1 for your reference, 1 for the JP, 1 for the Crown and 1 spare), which includes original request (signed in ink), fax receipt and your call log (if you have it).
4) Ideally you wanna send 2 requests. One as soon as you get your notice of trial (quick action also good for an 11b argument) and one about a month before the trial date. If you haven't received full disclosure 3 weeks before the trial, fax your form 4F (and a factum if necessary) to the AG's of Ontario and Canada and the Prosecutor's office. Bring extra copies to the court for the JP and the prosecutor.
5) If the Crown hasn't sent you all relevant information, you can still request a stay of your charges regardless of the fact that they sent you
something.
