The company says 17,736 of the recalled Camaros are in Canada. GM assembles Camaros at its Oshawa, Ont., assembly plant east of Toronto.
The company is recalling the muscle cars made between the 2010 to 2014 model years, because a driver's knee can bump the key and knock the switch out of the "run" position, causing an engine stall.
That could knock out power steering and brakes, and cause drivers to lose control.
GM says it knows of three crashes and four minor injuries from the problem.
The fix involves replacing the key — which is currently embedded in the key fob like a switchblade — with a straight design.
GM says the Camaro ignition switch problem is different from their other, larger recall of 2.6 million small cars for faulty ignitions, linked to more than 50 crashes and at least 13 deaths.
The company has been embroiled in a safety scandal since February, when it was revealed it knew about possible safety problems on millions of cars, but didn't act swiftly enough to fix them.
"“Discovering and acting on this [Camaro] issue quickly is an example of the new norm for product safety at GM,” said Jeff Boyer, vice-president of global safety.
