Prime Minister Justin Trudeau differs from many Canadians when it comes to morning rituals - he doesn't drink coffee.

"I just never developed a taste for it," Trudeau told a crowd in Kitchener, Ont. Tuesday during a stop at the video software company, Vidyard.

Trudeau made the revelation after being asked a quick fire question: Tim Hortons or Starbucks?

He said he had about three or four cups of coffee in university.

"Any time I actually had to make coffee is because I had to stay up and write a paper all night, but inevitably I would fall asleep and the coffee would fail," Trudeau said.

He said he also knows too many people who can't function until they've had coffee.

"I don't like to be dependent on anything external," he said.
