The projected change in the market share of large 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 1990 to 2010 period, which would affect vehicle preferences. Light-duty vehicles include all cars and light trucks. The pattern of spatial variation, in relation to the 1990 interpretation, remains largely unchanged in the projected market share of large cars for 2010. However, the projected changes from 1990 to 2010 vary significantly across Canada. It appears that areas with a low large car share in 1990 would have a more significant increase in this share over this period, while areas with a high large car share in 1990 tend to have a decrease in this class share over the same period.
