Sorry, this isn't a duty to warn, because, as much as I would like to have that, my understanding is that it's a provincial jurisdiction. This was adding that when someone is applying for a licence and you're looking at whether they have a criminal record, there's a number of criteria adding on to that, that they're a threat to themselves or others, or online public behaviour. We know that there have been a number of times where people have publicly posted things that would be triggers for someone looking at whether or not to approve a licence.
