At that point, midway through Friday, the summit’s outcome was very uncertain. Officials held out hope a full communique could be reached, but acknowledged the divides may be too great and that a different kind of document was possible.
Things warmed over the dinner, where Trump discussed North Korea at length, officials said, and had another private discussion with Trudeau. The leaders attended a performance that night, on a terrace in front of the hotel overlooking the majestic Saint Lawrence river.
Then came an impromptu push just before midnight. Trump, Merkel, Macron, May, Trudeau and Italy’s Giuseppe Conte gathered in the hotel lobby, with their officials releasing photographs of them talking closely over the documents. Japan’s Shinzo Abe -- who has sought close ties with Trump and been more measured in his criticisms -- joined later, officials said. They spoke for over an hour, and ordered their aides, known as sherpas, to haggle through the night.
