Transport Canada requires that speedometers must be calibrated in km/
h. That being said, there is no prohibition on
speedometers also displaying MPH, nor is there a requirement that the
km/h be the primary set of numbers when
both km/h and MPH are displayed. (That being said, if the car was
manufactured for the Canadian market and
if the speedometer simultaneously displays km/h and MPH, the km/h are
normally always the more prominent numbers).
Odometers and trip counters must be calibrated in km, but they may be
calibrated in miles if there is a label stating
the at the odometer is calibrated in miles. Again, odometers for
cars manufactured to be sold in Canada will have
odometers displaying km.
So, to summarize, in Canada:
A speedometer can be km/h, or both km/h and MPH (with no requirement
for km/h to be primary).
But, a speedometer could not display MPH alone (unless the car was
manufactured before the metric
requirements were implemented.)
An odometer can display km alone or miles alone, but if displaying
miles, a label must be displayed
showing this.
The reason that there is no requirement for the km/h to be the
primary numbers when both are displayed,
and to allow odometers to display miles as long as a label
accompanies it, is to allow for the legal
and permanent , importation of US market cars into Canada (normally
done by persons who move from the US to Canada and who bring
their cars with them). Their US speedometer meets Canadian
requirements, even if the km/h is the smaller set of
numbers. Also, since the US odometer may display miles alone, that
odometer would be legal in Canada by the
application of a label on the dash, stating that the odometer reads
in miles.

I guess I'm wondering more what the current practice is now, and
secondarily what the law allows (i.e, are the choices km/h only or
both km/h and mph provided that the km/h display is primary on dual
analog displays, etc;)_
