The difference between DND and CSIS mandates/powers

[thewatchmaker]

Maybe this is an obvious question, but given that both the DND and CSIS have 'national security' objectives, how much do their mandates overlap and what exactly is the difference between the two? (And how is it decided that a security issue falls under DND or CSIS purview?) If someone wants to help me understand how their purpose and powers are differentiated, please feel free to go into as much detail as possible.

DND as per Canada First Defence Strategy: http://www.forces.gc.ca/site/pri/first-premier/missions-eng.asp

That's about as much as I dare offer on this topic...

You can probably find as much on Wikipedia as is in the realm of public knowledge.  CSIS is a domestic security agency whose mandate is internal security of Canada and not operations abroad.

You may also want to look into CSEC. Its roughly the equivalent to the US's NSA.
