"Clearly we were expecting to have 11 nations represented around the table but one didn't show up so we were disappointed", he said.
The heads of the 11 countries that have been negotiating a revised Trans-Pacific Partnership had planned to meet on the sidelines of the Asia-Pacific Economic Co-operation leaders' summit in Danang, Vietnam.
Reuters said a statement was due to be made today, and it marked "a successful conclusion to talks in Vietnam", which at one stage had looked headed for failure amid resistance by Canada.
While APEC includes 21 member countries, the 11 nations of the TPP include Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore and Vietnam.
"It should come as no surprise and it actually didn't come as a surprise to people who'd noticed that I was saying that and have been saying that all week".
Canada, which has the second-biggest economy among remaining TPP countries after Japan, had said it wanted to ensure an agreement that would protect jobs.
That issue was resolved during the day before the aborted leaders' meeting.
The political drama included a scheduled meeting of TPP leaders that Mr. Trudeau did not attend and that was ultimately cancelled, leading to global media reports that Canada had "screwed" its TPP allies after getting cold feet.
It has been reported the no-show was a scheduling misunderstanding. A briefing to wrap up the ministerial meeting late on Wednesday was canceled after a delay of several hours, and talks have continued into Thursday.
"My guess would be the NAFTA talks make concessions on auto and agriculture incredibly hard as TPP could undermine those negotiations", said Geist.
Efforts to reach an agreement this weekend on a Pacific Rim trade pact appeared to collapse Friday when persistent concerns over the deal, including Canada's, forced the abrupt cancellation of a scheduled leaders' meeting.
The TPP negotiations originally included the United States, but U.S. President Donald Trump withdrew from the talks. The Canadian tech-sector has long urged Ottawa to fight for the removal of those elements from the deal. "TPP was not (the) Liberals' trade deal".
International Trade Minister Francois-Philippe Champagne quickly disputed the report.
"If we are blocking for fear of annoying the USA, that seems silly to me", said Derek Burney, a former chief of staff and Canadian ambassador to the USA under former Progressive Conservative prime minister Brian Mulroney.
On Sunday, Trudeau will attend the ASEAN summit of 10 Southeast Asian leaders in Manila, hosted by President Rodgrigo Duterte, who has faced harsh worldwide criticism for his human rights record.
The Canadian team had no plans to agree to the deal at Friday's TPP leaders' meeting unless the modifications were made.
Mr Trump and the other 20 leaders of the APEC economies will on Saturday retreat into the Summit for private talks.
"We will work through this and we have, of course, additional opportunities in the future for us to reconvene to keep working through these issues, and hopefully we will be able to find a pathway forward that accommodates the requests from Canada".
