Kinda overlooking the fact that Lester B Pearson won the Nobel Peace Prize for his leadership in Canada's efforts to lead a neutral force to force peace in the Suez Canal.
Interestingly, as a British person, I've never heard of Lester B Pearson before your comment. Possibly for the same reason it took me so long to find out even a single negative thing about the British Empire: the UK not wanting to talk about anything embarrassing in its history.
