Mr. Speaker, these petitioners mark the fact that children ordinarily thrive the best when raised by both parents. Despite that, courts actually favour mostly sole-custody. Therefore, the petitioners are asking Parliament to amend the Divorce Act to require equal shared parenting to be treated as the rebuttable presumption in custody decisions, except, of course, in cases of proven neglect or abuse.
