No. In fact, even with the goods coming across the border by importers and even though the Canada Border Services Agency has done a number of inspections and identified things like misclassifications and that the misclassifications have resulted in an under-collection of duties, they themselves haven't done any estimate even of that information, of what the total quantum might be. They haven't taken the information from those more focused activities that indicated that they're not collecting all the revenue that they could collect. They haven't even taken that to extrapolate it, let alone some of those other more difficult things to extrapolate, such as people coming across the border with things.
