A man has sustained life-threatening injuries after a reported home invasion involving gunfire in Markham, York Regional Police say.

Emergency crews were called to a residence on Boxwood Crescent, near 14th Avenue and Ninth Line, on Monday afternoon for reports of shots fired inside.

"Two suspects entered the home. That’s when the shooting occurred,” Const. Andy Pattenden said. “Those suspects then fled the residence in a dark-coloured vehicle.”
