Liberal Leader Justin Trudeau spoke for the second time to thousands of party supporters gathered in Montreal for the Liberals' biennial policy convention. It's his first such gathering as leader, and the last the party will have before the next election. Here are the five most important moments of the speech.

'Nathalie'

No rear-view mirror
Justin Trudeau used his speech Saturday to pivot off the youth and energy of the convention. He didn’t look back at the past accomplishments Liberals love to brag about (balanced budgets or not joining Americans in Iraq). Rather, he looked ahead, describing the government he wants to lead and the choices Canadians will have for the 2015 federal election.

Positivity vs. negativity
Mr. Trudeau likes to contrast what he believes is his hopeful, optimistic approach with the so-called divisive approach of his opponents. “Like Mr. Harper, Mme. Marois [Quebec Premier Pauline Marois] practises a divisional policy,” he told Liberals in his speech. “Negativity cannot be this country’s lifeblood,” he said at another point in his remarks. Then there was this line about Mr. Mulcair and Mr. Harper: “Both of our opponents feel, for their own reasons, that the angrier Canadians get, the better they will do." His audience loved it.
