There are several sites that anyone following the Cold War and war time era Royal Canadian Navy might be interested in.

RCN Photographs and stories This site was set up and maintained by Charlie Dobie who like me was a sonarman and served on HMCS St Therese a Prestonian class frigate when I was on HMCS La Hulloise. The site allows former sailors to post stories and photographs from their own collections.
