Presumption of equal shared parenting?

Should there be a presumption of equal shared parenting in the courts- ie. where separated parents spend a relatively equal amount of time caring for their children? In an article in the National Post, Barbara Kay argues that it’s time for this presumption to gain a foothold in family law disputes. Her article points out that although we have a Family Law Responsibility Office in Ontario to collect and enforce support payments (generally against men), we don’t have an office dedicated to ensuring that non-custodial parents (usually men) have meaningful access to their children.
