If you are operating a mobile HAM radio in Canada (get it, Canadian HAM == Canadian Bacon - ha ha - groan) you need to state your callsign as:

mobile where is the ITU code for the region.  E.g.

VE1 for Nova Scotia
VE2 Quebec
VE3 Ontario
VE4 Manitoba
VE5 Saskatchewan
VE6 Alberta
VE7 British Columbia
VE8 Northwest Territories
VE9 New Brunswick
VE0 maritime hams

The RIC-2 document is located here, and is where the "mobile designator" and location requirement comes from.
