"Lordstown has been part of the GM family for more than 50 years so it's painful to see this happen to the plant's workers, their families and the community". Plants without products include assembly plants in Detroit; Lordstown, Ohio; and Oshawa, Ontario.
America's largest vehicle maker said some workers would transfer to SUV and truck factories, which are increasing their output because of growing demand.
In 2008-09, as the auto industry teetered, the Ontario Liberal government gave $3.6 billion to GM.
Those cuts are in addition to $6.5 billion that the company has announced by the end of this year.
"The actions we are taking today continue our transformation to be highly agile, resilient and profitable, while giving us the flexibility to invest in the future", said CEO Mary Barra, in a statement.
The US plants are in places that have been economically devastated by job losses and pressure on wages for decades, which helped lead to the 2016 election of Donald Trump as US president.
In an investor call, Barra said some GM cars would no longer be available in North America, including the Chevrolet Cruze. The money freed up by these cuts will be used to strengthen the development of GM's electric vehicles, as well as its upcoming autonomous cars.
According to payrolls data from Statistics Canada, there were 43,300 Ontarians employed in motor vehicle manufacturing as of August 2018.

The trio of Ukrainian ships were taken to port in occupied Crimea and have been held there along with 23 Ukrainian sailors. Since Russia annexed Crimea, tension has risen with both countries complaining about shipping delays and harassment.
The company estimates that the cuts will save it $6 billion by the end of 2020.
GM shares jumped after the announcement, closing up 4.8 per cent on the day.
GM's latest move includes the possible closure of seven plants worldwide, as the firm shifts its focuses from away from a stagnant sedan/saloon auto market.
GM is also moving to cut capital spending overall, even as it says it will double the resources dedicated to electric and self-driving vehicles over the next two years. "They better put something else in", Trump, who has pushed for more manufacturing jobs throughout his nearly two years in office, said. The official spoke on condition of anonymity because they were not authorized to talk publicly ahead of Monday's announcement.
The U.S. automobile manufacturer announced Monday it plans to cease work on the Chevrolet Cruze at a Lordstown, Ohio, plant and on three Chevy, Buick and Cadillac models at a Detroit-Hamtramck facility in MI.
Detroit-Hamtramck now builds the Chevrolet Volt, Chevrolet Impala, Buick LaCrosse, Cadillac CT6.
On top of the previously announced closure of the assembly plant in Gunsan, Korea, GM will also cease the operations of two additional plants outside North America by the end of next year.
The Oshawa announcement also raises questions about the future of GM operations in Ingersoll, which now produces the third-generation Chevrolet Equinox, and the St. Catharines engine operations, which produces engines and transmissions that are shipped to 10 different GM assembly plants across North America.
In its latest report, GM said combined sales of the Chevrolet Tahoe and Suburban and the GMC Yukon full-size SUVs were up 12 percent.
