I don't know what's been going on in Quebec, but I can tell you that it has been used in a limited way in Alberta in restoration hearings when there are proceeds of crime or there's a forfeiture hearing. The cross-examinations on any affidavits that are filed for that have been going through that civil questioning. It has been working.
It's also available in the criminal appeal rules, so when you appear before a court, if you have fresh evidence, if you do any of those applications that are by way of an affidavit, that's what's done. You go through the civil questioning rules.
I don't know what the experience is in Quebec, but it's certainly something that is not foreign to the criminal procedure and the criminal process.
