There are a number of websites dedicated to this special day of honour, including
Veterans Affairs Canada but my personal favourite is the webpage that the RCMP has dedicated to this cause.
On the left hand side of the page, you can read personal journals of modern day Peacekeepers. A great history lesson - given in a first person account.
