General Motors has announced it's laying off 3500 workers across North America, including about 970 at the truck assembly plant in Oshawa this September.

Oshawa - General Motors has announced it’s laying off 3500 workers across North America, including about 970 at the truck assembly plant in Oshawa this September.

C.A.W. local 222 president Chris Buckley calls it “another dark day for Oshawa.” Just 3 months ago, another shift and a thousand jobs were lost.

General Motors, which says demand for full-size pickup trucks is falling, blames a deteriorating economy and soaring gas prices for the cuts.

This news comes as major international oil companies are reporting record multi-billion dollar profits. They say it’s because oil prices are soaring and sales are up. Royal Dutch Shell, Europe’s largest oil company, made more than $9 billion in the first quarter, up close to $2 billion from a year ago. BP reported making $7.6 billion, up 63 percent in a year.
