A recent Justice Canada study estimated the cost of one type of intimate partner violence, spousal violence, on Canadian society at .4 billion in 2009 (Zhang et al. Most of these costs were related to victim costs, such as pain and suffering, counselling expenses and legal fees for divorce, while the next highest costs were borne by third parties (, police, courts, corrections).
For the purposes of this section, police-reported data are used to examine the prevalence and nature of intimate partner violence coming to the attention of police in Canada.
Disaggregated population data do not exist for previous common-law partners, current dating partners, previous dating partners, current same-sex spouses, and previous same-sex spouses.
Rates generally declined with increasing age and were higher for women in every age group.
Description for chart 3.1 Somewhat different findings emerged when intimate partner violence escalated to homicide and this was the case for both women and men.
Calculating rates among particular types of intimate partner unions, such as common-law and legally married unions, as well as specific relationship statuses, namely current versus previous partnership, is limited to the Homicide Survey.
This is because the accused-victim relationship categories within the Incident-based Survey do not match population data.
