Liberal Leader Justin Trudeau invoked a word his father once famously used in the House of Commons, using it as an adverb to emphasize his passion about boxing.
It's led the Prime Minister's Office to question Trudeau's judgment.
Trudeau is speaking at the Ajax-Pickering Board of Trade, just outside of Toronto, at 1 p.m. ET. CBCNews.ca will carry the speech live.
Trudeau was at a charity boxing event Saturday night in Gatineau, Que., the same one at which he pummelled then-Conservative Senator Patrick Brazeau in 2012.
Speaking from the ring, Trudeau said it pained him to be standing there and not suited up to take on an opponent.
"I will tell you, there is no experience like stepping into this ring and measuring yourself. All that — your name, your fortune, your intelligence, your beauty — none of that f--king matters," Trudeau can be heard saying in a video of the event posted to YouTube.
The line was met with huge cheers from the fight night crowd.
'Lack of judgment'
A spokesman for Prime Minister Stephen Harper wasn't as enthusiastic.
"This is yet another example of Justin Trudeau's lack of judgment," Harper's spokesman said in an email to CBC News.
In 1971, his father Pierre, then the prime minister, was accused of mouthing a profane phrase in the House of Commons to Conservative MPs John Lundrigan and Lincoln Alexander. Asked about it later, Pierre Trudeau referred to the term as "fuddle duddle." He also accused the MPs of being sensitive and going "crying to mama."
The younger Trudeau has been known to use coarse language in the past. In 2011, he called then-environment minister Peter Kent a "piece of shit" in the House of Commons.
