Liberal Leader Justin Trudeau says he learned long ago not to pay too much attention to the criticism levelled against him or his family name.

Trudeau was in CTV's Canada AM studios Friday and was asked by an audience member about how he鈥檚 handled attack ads during this long campaign. The Liberal leader responded that he was raised to disregard what people say about him or his father -- whether positive or negative.

鈥淚 developed a strong sense of who I am, and I don鈥檛 spend a lot of time worrying about what people who don鈥檛 like me have to say about me,鈥 he said.

He added he has tried to keep his campaign focused on 鈥減ositive change鈥 and deliberately chose not to run personal attack ads.

鈥淚 don鈥檛 believe in attack ads,鈥 he said, 鈥淚 think they hurt your ability to govern and my capacity to stay positive and focused on our platform.鈥

The Liberal leader was then asked the same question that hosts Bev Thomson and Marci Ien asked of Tom Mulcair: Tim鈥檚 or Starbucks?

While the NDP leader said his preference was for Starbucks, Trudeau revealed he doesn鈥檛 drink coffee at all.

鈥淚 know too many people who rely on a cup of coffee in order to get through the day,鈥 he explained. 鈥淚 don鈥檛 like being dependent on anything.鈥

Other revelations from the hosts' "This or That" questions:

Who鈥檚 better: Bobby Orr or Bob & Doug?

鈥淎s much as I love Bob & Doug,鈥 Trudeau responded, 鈥渢hey鈥檙e a parody of what it means to be Canadian. Bobby Orr is an extraordinarily inspiring person.鈥

Butter tarts 鈥 with raisins or without?

鈥淚f I鈥檓 going for a butter tart, I鈥檓 going to want the pure butter tart, with no raisins,鈥 he said. 鈥淩aisins have their place but -- I鈥檓 reaching out to the raisin constituency here -- but give me butter tarts clean.鈥

The two Margarets 鈥 Atwood or Laurence?

鈥淭rudeau,鈥 the Liberal leader responded without hesitation.

Trudeau explained that all his life, people have been coming up to him to say 鈥渨onderful things鈥 about his father. But over the last few years, more people want to talk to him about his mother and the work she鈥檚 done on mental health.

鈥淎nd I鈥檓 just so incredibly proud to be her son. It鈥檚 something I don鈥檛 get to say enough,鈥 Trudeau said. 鈥淎nd on Thanksgiving weekend, let me just say: I love you, Mom.鈥
