"We're very unhappy with the negotiations", he said, "and the negotiating style of Canada".
Hours earlier, in New York, Trudeau gave Canada's NAFTA-talks nemesis a gentle nudge during his own closing news conference that followed the General Assembly. "We will continue to negotiate with a view to getting a deal that is in Canada's national interest", he said.
Trudeau replied that he was not asked for a meeting.
After spending the last few days meeting with other world leaders, speaking about Canada's contributions globally, and campaigning for a seat on the UN Security Council, the ongoing uncertainty over NAFTA and tensions between Trudeau and U.S. President Donald Trump persisted.
Lighthizer said Canadian negotiators have refused to make concessions in essential areas for the Americans. "We have no more comments", - said the press-Secretary of the Trudeau Chantal Gagnon. I think Canada wants to do it, I know we want to do it, and we'll see what happens.
Canadian Prime Minister Justin Trudeau has never extended an invitation for a meeting with U.S. President Donald Trump in NY, according to a report by CTV on Wednesday night. "I think our view is now we'll turn to that as a next stage".
On dispute resolution, the Trudeau government wants to keep some form of NAFTA's Chapter 19 panels and the USA wants to eliminate them.
The US and Canada are basically out of time to iron out their differences in a trade agreement before the Sept 30 deadline to have a completed full text.
It's unclear exactly which representative Trump was referring to.
Lighthizer is expected to submit text Friday that leaves Canada out of the agreement, Bloomberg reported Wednesday.
Canada is the United States' second-largest trading partner.
The U.S. imposed tariffs on imported steel and aluminum from some countries in March and added Canada, Mexico and the European Union in June. Canada imposed tariffs on $12.5 billion of United States goods, including steel, toffee, maple syrup, coffee beans and strawberry jam.
"We don't know if there could be some last minute announcement this week between the United States and Canada, but we are in any event preparing for the situation where we release the text bilaterally and that Canada may join over the next few weeks", he said.
"It's really a question of whether or not the United States wants to have a deal. We have no comment", she said.
If the apples of discord between Canadians and Americans persist, the administration Trump will ask the Congress to approve such an agreement only with Mexico, he explained.
