In the mid-1960s the Ontario Law Reform Commission (the "Commission") initiated a research project on areas of family law within the legislative scope of the Province of Ontario.1 The Commission appointed the writer of this comment as the Director of the project, which was called the "Family Law Study" (the "Study"). At the time the Study was written there was much interest in various parts of the world in the reform of matrimonial property law; the amount of basic legal re-assessment was unusual in the ten years or so before the Study began work. Some of the impetus for these reforms and researches had come from the Scandinavian countries in the 1920s. The Study reported to the Commission, in twelve volumes of research and recommendations, during the next three or four years. The Commission thereafter issued a related set of reports, with recommendations, to the Attorney General of Ontario. The Commission's recommendations were in substantial agreement with those of the Study. These recommendation in turn led to the Ontario Family Law Act of 1986,2 the matrimonial property arrangement of which is the subject of this Comment. Property arrangements of husband and wife usually fall into one of two broad classes, namely: (A) The couple have chosen an arrangement where one spouse is employed outside the home, and is the "wage-earner," and the other spouse remains at home to look after the domestic affairs and any young children, and is not a "wage-earner" (except perhaps on a part-time or temporary basis). In this case, the couple might (but not necessarily) prefer a "partnership" type regime. (B) The couple have chosen an arrangement where both spouses are employed outside the home, and are "wage-earners" on a more or less permanent basis. In this case the couple might (but not necessarily) prefer a "separation" type regime.
