In April 1991, Greene called for existing tax and social benefits to be rolled into a single national child support program targeted to benefit low-income Canadians. Greene argued that existing benefits favoured wealthier families over the poor, and that the balance needed to be changed. Critics expressed concern that the proposed changes would threaten the universality of these programs, and reduce benefits for vulnerable middle-income families. The Mulroney government implemented the child tax credit program but did not implement the recommendations in the report for a national day care program which it had initially supported. Greene tried to convince her government to re-establish the program later in the year, without success. Greene also sought to create a national standard for social assistance to eliminate the wide disparities between the provinces.
