The gridded difference file AB_CSRS.DAC in STEP 1 will need to be renamed to AB_CSRS.gsb to run in some software suites. Formats identical, but AB file is provincial fit only.

Topographic mapping (small scale).
Data may sometimes be referenced to NAD83(CSRS) / STC Lambert (see CRS code 3348) which is then called "NAD83 / STC Lambert". At the scales involved the difference of under 2 metres between the two CRSs may not be significant.
Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north. UoM: m.
