As with forced marriage, there's no actual legal category of honour killing, so we don't have any statistics through Statistics Canada that would identify percentage of homicides that were actually related to honour.
However, we have examined reported cases and identified around a dozen cases that appear to have been related to honour. Not all of these cases, of course, involve the defence of provocation. They were not always raised in all of those cases, for sure. The commonality between these cases is that either the defence raises or the prosecution identifies the case as being related to the family honour as being one of the motives for the actual killing.
