TORONTO -- The leaders of the six major federal parties went head-to-head in a fiery debate Monday night in a room full of undecided voters. It was a chance for the leaders to convey their plans to Canadians, win over new votes, and, of course, throw in a zinger or two towards an opponent.

Catch up on who said what to whom with CTVNews.ca鈥檚 roundup of the most noteworthy digs of the debate.

1. In response to Conservative Leader Andrew Scheer鈥檚 鈥渘on-response鈥 to the first question from an audience member about the values of Canadians on the world stage, Green Party Leader Elizabeth May quipped: 鈥淚鈥檇 like to answer the question, in contrast to what we just heard.鈥

2. On the subject of climate change, Bloc Quebecois Leader Yves-Francois Blanchet told the People鈥檚 Party of Canada Leader Maxime Bernier: 鈥淪omebody invoking the truth shouldn鈥檛 be somebody denying climate change.鈥滲ernier attempted to interject to say, 鈥淚 don鈥檛 deny climate change.鈥 (In an with CTV Question Period on Sept. 15, Bernier disputed the science behind climate change, saying 鈥渢here is no climate change emergency in this country").

3. Liberal Leader Justin Trudeau took a double-shot at Bernier and Scheer on the subject of immigration, diversity and being a 鈥減roud Canadian.鈥 Trudeau said: 鈥淢r. Bernier, your role on this stage is to say publicly what Mr. Scheer thinks privately.鈥 

4. Blanchet got the final say at the end of a lengthy sparring match he had with Scheer over building pipelines through Quebec. After Scheer repeatedly said that he had 鈥渕ade his choice鈥 about where Quebec should buy its energy from, the Bloc leader retorted: 鈥淵ou have done and Quebec will make his.鈥

5. When Bernier confronted NDP Leader Jagmeet Singh about not wanting to share the same stage because they disagree about immigration, Singh fired back: 鈥淎fter a couple of minutes of this debate tonight, I think people can clearly see why I didn鈥檛 think you should deserve a platform.鈥

6. In a Scheer-versus-Trudeau exchange about climate change in which they spoke over each other, Singh looked at the camera and said: 鈥淚 want to say this directly to Canadians: you do not need to choose between Mr. Delay and Mr. Deny. There is another option.鈥

7. In response to constantly bringing up Ontario Premier Doug Ford, Scheer quipped to Trudeau: 鈥淢r. Trudeau, you seem oddly obsessed with provincial politics. There is a vacancy for the Ontario Liberal leadership and if you are so focused on provincial politics, go and run for the leadership of that party.鈥

8. As Trudeau and Scheer went back-and-forth about abortion rights, Singh interjected to say: 鈥淎 man has no place in a discussion on a woman鈥檚 right to choose.鈥 And May shot back right: 鈥淗ow about a woman鈥檚 right to speak?! It鈥檚 been really interesting for most of this campaign to hear a lot of men arguing about what a woman鈥檚 right should be.鈥 She pointed out how she was left out of the French-language on Oct. 2, which failed to give the opportunity for 鈥渓ittle girls to see a woman could be the next prime minister.鈥

9. In what could be the hardest hit of the debate, May concluded: 鈥淢r. Scheer, with all due respect, you鈥檙e not going to be prime minister.鈥 Scheer said he鈥檇 prove her wrong and she quipped back: 鈥淚鈥檒l take bets on it right now!鈥
