The Theme
This map shows, for the populated area of each census division,
the projected change in the market share of subcompact cars in total
light-duty vehicle sales, from the model year 1990 to 2010 (the
base year and the target year of the Kyoto
Protocol), based on the business-as-usual scenario. The business-as-usual
case assumes that there are no major policy changes in the 1990
to 2010 period, which would affect vehicle preferences. This change
was derived based on the 1990 market share and the 2010 market share
projection. The 2010 market share projection is provided as an alternative
layer in this map.
Light-duty vehicles include all cars and light trucks. The light-duty
vehicle size classes, defined by the US Environmental Protection
Agency, were adopted for the vehicle classification. This classification
has 15 classes: six classes for automobiles, six classes for light
trucks, and three classes for station wagons. Among these 15 classes,
seven prominent classes account for the large majority of new light-duty
vehicle sales in each census division. The prominent classes are
subcompact cars, compact cars, midsize cars, large cars, small vans,
small utility vehicles and large pickups. The remaining classes
include two seater cars, minicompacts, small pickups, large vans,
large utility vehicles, and three size classes of wagons.
Note that there are no data available for the Territories.
Relation to Climate Change
Because vehicles consume a substantial part of energy in Canada,
average vehicle fuel efficiency is an important indicator for greenhouse
gas emission and climate change policy making. The lower the fuel
efficiency, the higher the emission per vehicle, and, consequently,
the greater the contribution to greenhouse gases. Average new light
duty vehicle fuel efficiency, which measures miles travelled per
gallon, is defined by averaging the tested fuel efficiency
rating for each vehicle's class, weighted by that class' market
share in each census division. Vehicle market share is therefore
one of the two determinants to vehicle fuel efficiency. Subcompact
cars are normally the most fuel-efficient vehicles. For a particular
area, the larger the subcompact car share, the more fuel-efficient
the overall vehicles.
Map Interpretation
It is projected that the market share of subcompact cars would
remain largely unchanged from the model year 1990 to that of 2010
for Canada as a whole (18.8% in 1990 and 18.2% in 2010). There would,
however, be significant geographical variations in the change across
Canada. Eastern Canada would have relatively small changes in market
share, with some areas increasing and other areas decreasing. In
Western Canada, a decrease in market share would be the dominant
trend for Alberta and British Columbia, but there would be a dominant trend of
increase for most areas of Saskatchewan and Manitoba.
According to market share models, subcompact car market share has
a strong positive correlation to younger populations, as these small
vehicles are the most affordable to buy and to operate. Conversely,
subcompact market share has a strong negative correlation to household
income. The expected relative decrease in younger populations and
the increase in household income over the forecasting period (as
shown in Figures 1 and 2) should lead to a decrease in subcompact
market share.
However, this does not appear to be the case in approximately half
of the statistical areas in Eastern Canada. One possible reason
is that the expected increase in household income may lead to users
purchasing a new vehicle at an earlier age, and for this purchase,
a subcompact car would be the most affordable choice. This effect,
together with the ongoing price advantage of subcompacts over this
period (Figure 3) may counteract the expected trend of decrease
over this period. For Saskatchewan and Manitoba, the expected significant
increases are primarily due to another cause: a significant switch
from large pick-up trucks to small passenger vehicles as a result
of a projected reduction of farming as an occupation in this region.

Data Source
A case study was conducted at the GeoAccess Division of Earth Sciences
Sector, Natural Resources Canada, in collaboration with Transportation
Energy Use Division of Energy Sector, Natural Resources Canada,
in order to showcase a spatial econometric approach to modelling
in support of policy making. The
projection for the market shares of light-duty vehicles by census
division was produced during this study. More details on the spatial
econometric approach are provided in Methodology
for Projection.
The verification of this projection of light-duty vehicle market
share has shown its likely validity for forecasting shifts in the
mix of light-duty vehicle sales for a given model year in a short
to medium term. This projection, however, is based on a series of
macroeconomic assumptions in Canada's Energy Outlook 1997, which
represent a best guess for the possible future if there will be
no additional policy interventions. Generally, it is suggested that
an econometric projection should serve as a trend forecast rather
than a numerical forecast.
An official projection for vehicle fuel efficiency and market shares at provincial and national levels can be found in Canada's Emissions Outlook: An Update 1999.
