In the French version, Mr. Perron, the preamble reads as follows:
In 1956 the Minister of External Affairs, the Right Honourable Lester B. Pearson, proposed the first United Nations peacekeeping mission, and, since that time, Canada has been a leader in keeping the peace around the world, with more than 100,000 members of the Canadian Forces participating in peacekeeping and peace-support missions along with many members of Canadian police services, diplomats and civilians;
Instead of the word “missions”, we would use the word “operations” and add the words “diplomats and civilians”. I presume that you would also want to amend the second and third paragraphs of the preamble to include “peacekeepers”, followed by the words “Casques bleus” in quotation marks.
Although I'm not sure of this, I believe, Mr. Perron, that it would normally appear in parentheses.
