The Canyon Fire, which started Monday afternoon along the 91 Freeway near the Orange-Riverside county line, had grown to 2,000 acres by 9 p.m. and was 5 percent contained, authorities said.
Some schools were scheduled to be closed Tuesday due to poor air quality and residents in the evacuation zone could go to Corona High School for shelter. About 300 firefighters from around the region were battling the fire.
