Toronto police are searching for at least two suspects after shots were fired during an armoured vehicle robbery Monday night at Fairview Mall.

The robbery happened at about 10:30 p.m. outside the TD Canada Trust bank in the northwest corner of the mall, which is located at Don Mills Road and Sheppard Avenue East.

Supt. Neil Corrigan told reporters that the suspects emerged from a parked car and approached the G4S armoured vehicle, which had just arrived at the mall.

Corrigan said there was "a discharge of firearms" by both sides at close range, though he could not yet say who fired first.

"Quite frankly, under these circumstances, it’s quite remarkable that no one appears to have been injured at this point," he said.

A bullet hole could be seen in the front window of the armoured vehicle on Tuesday morning.

The suspects fled the scene with an undisclosed amount of money.

A spokesperson for GardaWorld, the company that now owns G4S Cash Solutions, told CBC News that it is co-operating with police and would not be making a comment on the robbery.

Corrigan said that police had obtained video images of the event.

The superintendent said that police also have descriptions of the suspects, though they will not be releasing the information at present.

Police found a Dodge Caravan on a nearby residential street they believe was the getaway vehicle. The van was left with its lights on and engine running.

Corrigan said that anyone with information about the robbery is urged to call investigators at 416-808-3300.

"When people engage in this type of activity, it’s something that we have to deal with in an appropriate fashion and a speedy fashion," Corrigan said.

According to figures from Unifor, the country’s largest union in the private sector, there have been more than 70 attacks on armoured vehicles in Canada since 2000.

Unifor national president Jerry Dias issued a statement Tuesday, saying the incident at Fairview Mall was indicative of the dangers that armoured car personnel face every day.

"Our immediate concerns go out to the families of these guards ... as well as members of the public in the area at the time, who were put in danger by this violent robbery," Dias said.

Unifor does not represent the G4S workers involved in the Monday night incident, though the union does represent other armoured car drivers in Canada.
