Speaking Thursday, Ryan indicated if the U.S., Mexico and Canada could reach an agreement soon, meaning Congress could still take it up this year.
This comes as Canada's prime minister said he feels positive about NAFTA talks, and that there's a good deal on the table.
"It's right down to the last conversations".
Adam Austen, Press Secretary for Canadian Foreign Affairs Minister Chrystia Freeland, said in a media statement that "the process of congressional ratification is internal to the US", not a matter for Canada.
President Donald Trump's trade team is running out of time to rewrite a trade pact with Canada and Mexico this year even as it negotiates with China and spars with its allies over USA tariffs on imported steel and aluminum. Mr. Austen also said that Canada, the USA and Mexico have made "good progress" during this spring's talks, particularly on issues impacting the automotive industry.
Moreover, presidential elections take place in Mexico in July, and the expected victor, Andrés Manuel López Obrador, is a populist who could take a harder line on NAFTA.
"Any renegotiated NAFTA that implies losses of existing Mexican jobs is unacceptable", Guajardo said in a tweet.
The Trump administration's plans to overhaul the North American Free Trade Agreement may have to wait until next year.
But here is the thing - While nations such as Canada and the U.S, might be feeling positive about NAFTA, Mexico is a different bag of "frijoles" altogether.
Ildefonoso Guajardo told his country's Televisa network that he doesn't see a deal happening by Thursday, which the U.S. Congress calls the latest possible date to get a deal in order to have time to vote on it this year.
Edward Alden, a senior fellow at the Council on Foreign Relations, told NPR Ryan could probably find a way to postpone the deadline a few days if the countries were on the verge of an agreement, but that's not the case.
