The projected change in the market share of compact cars in total light-duty vehicle sales, from the model year 1990 to 2010 based on the business-as-usual scenario is shown on this map. This scenario assumes that there are no major policy changes during the 1990 to 2010 period, which would affect vehicle preferences. Light-duty vehicles include all cars and light trucks. The projection shows that, between the model years 1990 and 2010, the market share of compact cars in Canada would decrease from 27% to 20%, specifically, areas in the Atlantic Provinces and Quebec. There are also significant proportional reductions of market share in some areas of Alberta and British Columbia.
