WATCH: Trudeau stumped on his government's deficit tally

Conservative leader Pierre Poilievre during Question Period on Wednesday demanded to know the deficit the Trudeau Liberals rack up "day by day."

"We have a prime minister who is weak, and a weak economic position facing the threats from President Trump," said Poilievre.

"Not we learn the PM doesn't even know the extent of the deficit. Spending is out of control, and it goes up day by."

"How much is the deficit of the Government of Canada?"

Prime Minister Justin Trudeau was unable to answer.

"He can't say how big the deficit is? Even though he already had a budget for this year? That's strange."

"Let's ask him an easier question: What was the deficit last year?"

Again Trudeau could not answer, and accused the Opposition leader of "attacking" him.

"Whose actually running this government?" asks Poilievre.
