Andrew Cuomo sent Trump the letter on Tuesday.
The governor recently joined Wisconsin Gov. Scott Walker in writing a letter to President Donald J. Trump asking him to take action against Canada for its dairy pricing program, which limits the amount of dairy products exported across the northern border.
Canada's dairy sector, which includes C$6 billion ($4.45 billion) in annual farmer milk sales, is protected by high tariffs on imports and controls on domestic production as a means of supporting prices.
"Canada...what they've done to our dairy farm workers, it's a disgrace", Trump told reporters at the Oval Office Thursday as he announced that his administration will investigate steel imports as part of his "Buy American-Hire American" plan.
About 70 dairy producers in both Wisconsin and NY are affected by the decision. He threatened to tear up the North American Free Trade Agreement (NAFTA) unless there were substantial changes to what he called a "very unfair" system and he called trade rules between Canada and the USA a "complete and total disaster" for the U.S.
Trump's decision to call out Canada by name Tuesday put dairy farmers north of the border on notice they were in America's fair-trade sights. They could also affect the price and variety of dairy products on supermarket shelves.
"We're going to get together and we're going to call Canada, and we're going to say, 'What happened?' And they might give us an answer, but we're going to get the solution, not just the answer, OK?"
"We're going to have to get to the negotiating table with Canada very, very quickly", he added.
"The national ingredient strategy is industry-driven and was developed between dairy producers and processors", he said.
U.S. Sen. Charles E. Schumer, D-N.Y., said Wednesday that he would stand by Mr. Trump in working to change Canada's policies.
"President Trump's reaction is not surprising".
"We've had a tough time on softwood lumber for 30 years". "As a matter of fact, Canada's dairy industry is less protectionist than that of the USA, which has employed technical barriers to keep Canadian dairy out of the US market".
USA unease has been brewing for years over the dairy restrictions, and the issue complicated negotiations of a Trans-Pacific Partnership pact, an unratified 12-nation trade deal that Mr. Trump pulled the US out of in January.
The critical tone toward Canada contrasts with his warm words for Prime Minister Justin Trudeau when the Canadian leader visited the White House in February.
At the heart of objections from Mr. Trump is Canada's supply-management system for the dairy industry. "We'll have to wait and see", Stephenson said.
Canada Wood, an industry trade group, said earlier this month it would "take the first steps to extend its reach to Wuhan, which is the economic engine of central China", by establishing a joint Sino-Canadian Modern Wood Construction Technology Center in the little-known Chinese city of more than 10 million.
Ottawa's envoy to Washington is downplaying talk of growing trade irritants with the USA, a day after President Donald Trump called Canada out by name. He called them a "disgrace" to USA farm workers.
Trump appeared to be taking issue with Canadian dairy producer's decision to lower the price of dairy ingredients to make Canadian products more affordable, which drew business away from producers in Wisconsin and NY state.
