Deader than any cemetary, this is the Decarie Mall (Montreal)
Lies next to the Hippodrome, and Walmart, adjacent to the Decarie Expressway (intersection Jean-Talon). Not to be confused with another former dead mall, farther south along the decarie (near Queen Mary) which became a call-centre (glassed in...I also believe that there was a recent murder committed there by a call-centre worker that had gone 'postal').
