I notice all respondants so far have ignored the Navy and Airforce. Admitedly, the bulk of Peacekeeping Ops have been land oriented but not all. There are several exclusive Navy and/or Airforce ones as well. My suggestion would be to use a search engine after looking at some of the missions which entitle one to wear the CPSM(Canadian Peacekeeping Service Medal):

Though not "books" on the subject, I am sure you would find lots of info to steer you to titles.
Al I can say for books specifically 'Navy' are books by the following authors:
Ken MacPherson
Mac Johnston
Marc Milner
Thomas Lynch
James Lamb...
...to name a few.
I would ask one of my armchair historian brethern in 'light' blue to chime in on Airforce titles/authors.
