A voice could be heard over the speakerphone saying "President Pena Nieto", but still there was no Mexican leader on the line.
Trudeau spoke about the possibility of resolving a trade war last week, saying that he was "encouraged by the optimism expressed by the USA and Mexico", but added that "we also recognize that we will only sign a good deal for Canadians".
Canadian Foreign Minister Chrystia Freeland is headed to Washington on Tuesday to restart talks to replace the three-way NAFTA pact.
