Below are the links for some commonly used geoids used in Canada in a geoid field format (.gem).  Each region of Canada is represented in each of the download links. The files were created with 1500m spacing, and for use with the GRS1980 Ellipsoid.

Spatial Technologies provides these files as a courtesy to clients.  Clients may use them at their own risk and discretion.  For a complete list of Geoids,  it is recommended users download the geoid files directly from the NRCAN website.  The geoids downloaded from the NRCAN site will be in .byn format and require a conversation using Leica Infinity software to have them in a geoid field format (.gem).  Please refer to the following reference support page.
