The case for investing in high quality child care is compelling and unequivocal. The current challenge is to develop an architecture that will help guide the construction of a Canadian child care system open to all families that want to use it. This paper discusses four possible implementation mechanisms: a codicil to the Early Childhood Development Agreement, a new national child care strategy, bilateral agreements on child care and federal-municipal agreements on child care. These implementation mechanisms were developed in collaboration with the National Liberal Caucus Social Policy Committee, Chair, John Godfrey, MP.
