text: who is considered at the best prime minister in the history of canada? i would say pierre elliot trudeau is the best prime minister in the history of canada. pierre trudeau is certainly the prime minister who is most remembered and brought about a great deal of positive change - a multicultural, tolerant, understanding, bi-lingual society, good protection of our health care system, and repatriation of the constitution while maintaining good relations with great britain.  he greatly valued education and supported post secondary studies.  he is also remembered for the strong stand he took when he enacted the war measures act.  his phrase, "just watch me" is often quoted.  pierre trudeau was a true statesman, something we have not seen in prime ministers since him.  paul martin and stephen harper do not even come close to having the statesmanship, diplomacy, integrity, resolution or just plain charisma of pierre trudeau.  he will go down in history as one of canada's greatest.  to choose a runner up to pierre trudeau it would have to be either lester pearson who won a nobel peace prize, or john a. macdonald, one of the fathers of confederation.
