It's hard to measure what's not reported, but certainly we know, from decades of statistics in Canadian society and in fact around the world, that sexual offences are the lowest-reported offences. Typically, fewer than about 10% are ever reported. The ones that get reported tend to be the ones that are more severe in nature.
Within the Canadian Armed Forces, again, it's under-reported. The only way we can really look at that is if we look at the results from the StatsCan survey that measures anonymously people's reporting of victimization as compared with, say, the official police reports. There is under-reporting, for sure.
