"Using that type of language is not professional, it's not called for, and I tell you, I was deeply disappointed to see this lack of professionalism on his part".
Before the apology, some US lawmakers on Tuesday questioned the strong language the White House and Trump have used toward Canada in contrast to the praise he gave North Korea at Tuesday's summit in Singapore.
On Monday, MPs in the House of Commons approved a motion denouncing Trump's name-calling tirade and endorsing Trudeau's decision to stand his ground against USA tariffs and tweeted presidential threats.
Trump then tweeted Saturday evening, "PM Justin Trudeau of Canada acted so meek and mild during our @G7 meetings only to give a news conference after I left saying that, "US Tariffs were kind of insulting" and he 'will not be pushed around.' Very dishonest & weak".
A senior aide to US President Donald Trump apologized Tuesday for saying there was a "special place in hell" for Canadian Prime Minister Justin Trudeau, following the acrimonious Group of Seven summit.
At a news conference on Tuesday after his summit with North Korean leader Kim Jong Un, the USA president recounted his recent exchanges with Mr Trudeau. Trump said he was surprised to watch Trudeau's press conference aboard Air Force One as he flew to Singapore.
"Canada does not believe that ad hominem attacks are a particularly appropriate or useful way to conduct our relations with other countries", Freeland said.
Trudeau addressed the media on June 9 stating his intention to impose retaliatory measures on the USA from 1 July, as a necessary means to safeguard Canadian interests.
The U.S. and Canada are in the middle of renegotiating the North American Free Trade Agreement along with Mexico. And I say, push him around? Trump's chief economic adviser Larry Kudlow accused Trudeau of "stabbing the USA in the back" and said Trump's Canadian counterpart had attempted to undermine the president on the eve of an important summit with North Korea. "Our Tariffs are in response to his of 270% on dairy!" "It was very friendly", Mr Trump said. At the same time he was attacking the Canadian prime minister on Twitter, Trump reiterated his decision to have the U.S. Commerce Department review tariffs on all auto imports.
"If the U.S. decides to apply new tariffs, Canada will be ready", the official said.
And he confirmed that Canada would press ahead with dollar-for-dollar retaliatory tariffs on July 1 as previously announced.
"We've got to look at what supports are available to ensure that if their jobs, their livelihoods are compromised, what can the government do to support these folks".
