Russ,

I identified the projection as EPSG code 2036 (http://epsg.io/2036) -
please double check:

PROJCS["NAD83(CSRS98) / New Brunswick Stereo (deprecated)",
    GEOGCS["NAD83(CSRS98)",
        DATUM["NAD83_Canadian_Spatial_Reference_System",
            SPHEROID["GRS 1980",6378137,298.257222101,
                AUTHORITY["EPSG","7019"]],
            TOWGS84[0,0,0,0,0,0,0],
            AUTHORITY["EPSG","6140"]],
        PRIMEM["Greenwich",0,
            AUTHORITY["EPSG","8901"]],
        UNIT["degree",0.0174532925199433,
            AUTHORITY["EPSG","9108"]],
        AUTHORITY["EPSG","4140"]],
    PROJECTION["Oblique_Stereographic"],
    PARAMETER["latitude_of_origin",46.5],
    PARAMETER["central_meridian",-66.5],
    PARAMETER["scale_factor",0.999912],
    PARAMETER["false_easting",2500000],
    PARAMETER["false_northing",7500000],
    UNIT["metre",1,
        AUTHORITY["EPSG","9001"]],
    AUTHORITY["EPSG","2036"]]

However, it appears to be deprecated.

Using the http://grasswiki.osgeo.org/wiki/WxGUI#Location_wizard you
can selected this EPSG code in order to create a new location.

Hope this helps,

Markus
