You asked:
>>Are there any NON-COMMERCIAL sources of boundary files for the states of
the U.S., Canada, Mexico? Maybe free from some government agency or
geography group?<<
check out
ftp://ftp.ciesin.org/pub/census
This is a super place to find Atlas *.bna files and equivalent datasets from
the
1990 U.S. Census.... Organized primarily by document type: STF1b; STF3a;
etc., and census geographic level: state, county,tract, etc. I'm not
familiar with Mapmaker features, and don't know how/whether it can use Atlas
Import/Export to convert the boundary files from ASCII to the needed binary
format...
