Again, it's an extremely worthwhile point because we don't even have a national standard, let alone an international one. Other jurisdictions, whether it's the U.K. or in Hong Kong, can tell you whether they're meeting a national standard in the number of passengers they screen over x number of minutes or hours, or whatever it is.
In Canada, we've left that completely blank. One of the recommendations we've made is to pursue an enforceable standard so that service providers can be held to account, so that it's not just a case of, it's great today, it's bad tomorrow, etc. There's no national rule.
