- the Light Pollution Abatement Committee runs the national Light Pollution Abatement Program;
- series of public lectures that are open to the public and held across Canada in conjunction with the RASC General Assembly;
- National Archives housing the Society's collection of rare books and journals along with a reference library.
In addition to the programs sponsored by the Society there are many local programs that are offered and managed by member Centres of the Society.
