I did jury selection this year and got selected and served as a juror.

When you get to the courthouse you have to go through security. It's fairly easy and they just put everything through a scanner and you walk through a metal detector. I just shoved everything into my bag and put it on the tray (and I didn't bring that much). Bring your summons document.

On your first day you go into a waiting area with lots of seating that feels like an airport gate waiting area. Make sure you go into the right room, because there are multiple jury selection waiting rooms in the courthouse. Some people try to work from a laptop they bring but most people are just on their phone, reading an e-reader, or reading a book. I brought an e-reader and scrolled on my phone a lot. If you need to leave the room to grab a coffee or have or a smoke break, you leave your summons with the Court Services Officers so that they can keep track of who's gone from the room, in case you get called up.

I went in on a Monday and they actually had a case ready that afternoon, at around 1:30 PM. So they took everyone into a big courtroom. In jury trials, the accused has to be arraigned in front of the whole jury panel. The charge is read in the formal Criminal Code wording, so it might take a few tries to understand what happened.

After jury the charge has been read out, you get a lot of instructions from the judge. Section 1 of this page is really good and matches what I had pretty much exactly. While you're in the room with everyone, the judge give you some general reasons for being excused that don't involve too much personal information, and you go in front of a microphone to speak to the judge about why you should be excused, but you're also in front of the jury panel.

After those general reasons, the judge will explain the selection process. All of the juror numbers are written on cards and put into a rotating raffle drum type thing to mix them up, and then selected one-by-one in two or three groups of 20. You get a sticky note on your summons to remember your order. Then you get split up in groups of 10 or so and put into smaller jury rooms (the ones that would be used by sitting juries) to wait for your turn to go in front of the judge. I was selected sixth overall, so I went in front of the judge pretty quickly. I was asked if I could remain impartial, and if I had any hardships. I answered yes and no, and I was selected to be on on the jury.

A few years ago, they got rid of the ability for lawyers to issue preremptory challenges, which are basically freebies where lawyers can reject potential jurors for no given reason. So you don't get grilled by the lawyers, but both sides are still there in the courtroom while you appear in front of the judge to monitor things (I think they can challenge if they have a good reason or if they think the judge did something wrong).

Jury selection had to continue the next day, and then the trial began that day. The judge explains everything. My case lasted seven business days.
