A spokesman for Trudeau told the New York Times that the prime minister is focusing on "everything we accomplished here at the summit".
In a news conference June 9 shortly before his departure from Quebec, Trump brings up his problems with trading with his friends - "It's going to change, a hundred per cent". "This, I've never seen before". How many women wear false eyebrows?
Foreign Affairs Minister Chrystia Freeland followed, with a bit of Latin in her response: she said "ad-hominem" attacks weren't useful.
The comments come on the heels of a contentious visit to Canada for the annual G7 summit. Kudlow suggested on "Face the Nation" that Mr. Trump saw Trudeau as trying to weaken his hand before that meeting, saying the president won't "allow the people to suddenly take pot shots at him".

Trump's closest advisers added to the attack during televised interviews on Sunday.
"He's not going to tolerate that, nor should he", Graham said on Fox News.
Chief trade adviser Peter Navarro said there's "a special place in hell" for Trudeau and anyone else who negotiates in "bad faith" with Trump.
Trudeau said he had told Trump "it would be with regret but it would be with absolute clarity and firmness that we move forward with retaliatory measures on July 1, applying equivalent tariffs to the ones that the Americans have unjustly applied to us".
The prime minister responded by remaining above the fray. "Americans stand with you, even if our president doesn't".More news: Trump adviser apologizes for saying Trudeau has ‘special place in hell’
"We are like the piggy bank that everybody is robbing", he said.
Trudeau said at a news conference after Trump left the summit Saturday that Trump's decision to impose tariffs on Canadian steel and aluminum on the basis of national security was "kind of insulting".
In an appearance on CNN's "State of the Union," Kudlow argued that Trudeau's critique amounted to a betrayal of the G7, as well as the U.S.
"He did a great disservice to the whole G7".
One source of contention at the heart of the discussion at the summit was the steep metal tariffs that the US will be imposing on two of the country's largest trading partners: Canada and Mexico.
The motion in parliament, introduced by the opposition New Democrats, rejected "disparaging ad hominem statements by USA officials which do a disservice to bilateral relations".More news: Trump renews his criticism of OPEC for 'too high' oil prices
European G7 members expressed solidarity with Trudeau, as well as Republican Arizona Senator John McCain and ex-FBI director James Comey, who offered their support. "This must not be forgotten", the French president said. But he's really intimidated by @realDonaldTrump, and the sweat loosened the glue that keeps us attached.
