The vast majority of federal departments have public affairs wieners who put together a daily list of relevant news to that department....but not necessarily to the whole government. They are just getting with the program....
As an example, DND publically publishes
http://www.cfc.forces.gc.ca/257-Eng.html although this site pales in comparison to the internal information.
As an interesting and totally irrelevant factoid, did you know that most military public affairs officers washed out of some other occupational training? True shit....I kid you not!!!!
