Various methods have, in fact, been proposed and used. I am aware of a case in Nova Scotia, I believe, a few years ago. Because they had not targeted the francophone population, through a school board or another means, they had to ask approximately 900 people, or practically the entire population. They were able to come up with enough people to constitute the jury, but they did nonetheless contact some 900 people, if I remember correctly. So a problem remains. I was told, unofficially, that francophones had stated that they did not speak French, because they did not want to do jury duty.
So there are sometimes problems in that regard. However, many solutions have been proposed in various provinces, even if they have not all been implemented, since they did not necessarily need to form a jury. In some cases, it remained purely theoretical. Nevertheless, I think that is done. Practices vary from one province to another.
