You've had a couple of good ones in the past.
The issue of surveillance is really a critical thing in Canada because it's not ongoing. There is a surveillance system run by the major Toronto hospitals in the country. I think it's called CHIRPP. However, they only see a fraction of the trauma that is seen in sport because most of the time the injured party doesn't have to go to that trauma unit.
Keeping track of this kind of data is kind of a hit-and-miss affair, and it only takes shape when somebody decides they should collect injuries for three years. They do that. They do a nice job of it and make a report, but the report is issued two years after the last injury, so you're two years behind already. You can see trends, though. Then the surveillance stops, and we don't see it again for another 15 or 20 years, or until somebody is doing a Ph.D. or a master's degree and is interested in concussions in water polo or something.
It's an issue, really. I know that Hockey Canada, through their insurance program, tries to collect data, but again, it has to be an injury that requires insurance intervention. If it doesn't require insurance intervention, it doesn't necessarily get reported.
The CSA has an audit program where, if there is a faulty helmet and an individual is injured because the helmet's cracked or something, that gets reported to CSA and then down to the manufacturer, but that doesn't happen very often.
