According to the officials, the new trilateral pact, which will be called the U.S. -Mexico-Canada Agreement, or USMCA, includes provisions to prevent Canada's supply management system from affecting the world market in dairy products.
"Anything you submit to Congress will be trouble", he said.
Trump, flanked by trade ambassador Robert Lighthizer, adviser and son-in-law Jared Kushner and a who's who of his inner circle, called the new agreement the most important trade deal the USA has ever made.
"We lost two per cent access in the CETA deal, and we lost three and a quarter per cent access in the TransPacific Partnership", Gaunce said.
Wiens said the deal gives US dairy farmers greater access to Canada's supply-managed dairy system.
"I hope what they did in the renegotiated agreement is to make sure that the labor and wage standards in Mexico are lifted so that the playing field is more even now", Castro said.More news: Trump authorises expansion of Kavanaugh probe
In a big victory for Canada, NAFTA's Chapter 19 dispute resolution system, which involves anti-dumping and countervailing decisions, will remain intact.
Canada has offered access to its tightly controlled dairy market as part of other recent trade agreements.
"Canadians are polite, we're reasonable, but we also will not be pushed around", the prime minister said at the time.

"We look forward to further deepening our close economic ties when this new agreement enters into force", the statement reads.More news: Brett Kavanaugh’s classmate says he lied about drinking
Canada also agreed to get rid of its two-year-old Class 7 pricing agreement that has restricted US exports of ultra-filtered milk used to make dairy products.
"It's been a very, very disappointing day", said Wiens who farms near Grunthal, Man.
At a White House press conference, Trump said the treatment of Kavanaugh and his family by media and Democrats was "not describable". One of the officials said the discussions between Canada and the US were ongoing, but progress was being made. 20, said he's also hopeful, but he'll withhold judgment until after he reads what's in the agreement.
Marcelo Ebrard also acknowledged Monday "some of the new regulations, like the changes in the content rules, may pose some challenges for companies to adapt to".
