"In the U.S., the new trade pact will support high-paying manufacturing jobs and promote greater access for American exports across the range of sectors including our farming, manufacturing and service industries", Trump said.
After the three countries' leaders sign the pact, it must be ratified by their respective legislatures.
"There's much more work to do in lowering trade barriers and in fostering growth that benefits everyone", Trudeau said.
Canadian Prime Minister Justin Trudeau was less effusive about the renegotiated pact, but said the USMCA would resolve the threat of "serious economic uncertainty" that "would have gotten more damaging".
Trump himself acknowledged that it hadn't been easy, but said "battles sometimes make great friendships".
As of Friday, Canada's official website had a page dedicated to the agreement, which it called the Canada-United States-Mexico Agreement, or CUSMA.
President Donald Trump's signing of a massive new trade pact with Canada and Mexico on Friday was met with a skeptical response from Democrats during a press conference they held. Posing for photos in the gilded Salón Blanco, Trump spoke about their longtime personal relationship and said they would discuss trade, military purchases and other issues.

Outgoing Mexican President Enrique Pena Nieto is attending the G20 meeting. It updates the trade pact to reflect the rise of the digital economy since the original NAFTA took effect almost a quarter century ago.
Trump, standing in between his Canadian and Mexican counterparts, said the new deal was a model agreement that would stop auto jobs from going overseas, protect intellectual property rights and provide robust protections for digital trade and financial services.
"Make no mistake, we will stand up for our workers and fight for their families and their communities", he said. The United States is naturally putting America first with USMCA. Democratic Senator Elizabeth Warren said she would vote against the pact unless it is reopened to toughen labour and environmental standards, and does more to stop US companies from moving to Mexico. And while we don't know the final details of the USMCA, we do know that it largely resembles, in many ways, what was there before.
Under updated side letters released Friday, Canada and Mexico will have the power to "monitor and otherwise administer" how many cars produced by specific companies are protected from tariffs, but will have to "consult" with the United States on this.
USMCA also leaves unresolved the USA tariffs on steel and aluminium from Canada and Mexico.
She added that she will vote on the deal only if President Trump revises it.
The president canceled on Putin not long after his former lawyer, Michael Cohen, revealed he had lied to Congress to cover up that he was negotiating a real estate deal in Moscow on Trump's behalf during the Republican presidential primary in 2016.
