A security consultant who worked at the Eaton Centre during the 1990s says the mall appears to have changed little since June's fatal shooting.

David Nako says he conducted a survey of the shopping mall recently and recorded it, finding few cameras and no guards in about 30 minutes of wandering.

"When I can walk through the whole mall, and not see one security person there, then that really concerns me," he said.

Nako said a decade ago, the iconic shopping centre would have several guards on duty, including one posted full-time in the food court.

He said he doesn't understand why he saw so little security after the June 2 shooting in the mall's food court left two men dead and wounded five others.

"Where is the wake-up call?" said Nako, who has worked in private security for 26 years.

"If somebody came to me and said, 'Go down and check for me and see what's changed, see if anything has changed, so I can take my family down there and know that I'm going to be safe' … to be quite honest, I can't report back to them and say they've changed and they understand what's going on. I can't say that."

CBC News took a similar tour and saw one security guard in 20 minutes, but none in the food court.

The company that owns the Eaton Centre, Cadillac Fairview, said in a statement to CBC News that it can't comment on specifics, but officials said security is their top priority and they are reviewing security procedures.

Officials also said a person on the outside cannot fully understand or properly comment on security at the mall.
