If you want to extend your skills beyond the map package then you can plot anything that you can get a shapefile, or other common geospatial data set of, using the sp packages and friends such as maptools and rgdal. gadm has four levels of Canadian boundaries, at first glance - country, province (black), something smaller than province (blue) and then red which looks like urban divisions. The province upper-left doesn't seem to have any blue subdivisions, but that's possibly because there would be more subdivisions than people who actually live there. http://www.gadm.org/download Gadm also has a facility to download the data as .Rdata objects that can load straight into R. You might want to ask questions about spatial data programming on R-sig-geo or even on www.stackoverflow.com with the R tag.
