The Ajax resident has twice in a four-month period seen his 2004 Jeep Grand Cherokee targeted by thieves.

On April 17 and then again on July 4, Mr. Djorsev returned to the Ajax station to find the catalytic converter cut off his vehicle.

Thieves target the Jeeps because they're easy to get under, Mr. Djorsev said.

And, the catalytic converters are taken because there's platinum in them. If the thieves don't sell the converters for scrap, the entire unit would be resold, Mr. Djorsev said.

Replacing the catalytic converter cost $600 each time. So, he's out "$1,200, including towing," he said.

Mr. Djorsev approached GO staff "but I got nowhere," he said.

Following the first theft, "I parked under a camera because it happened the last time," he said. "I park under the camera for that reason."

When he told GO officials he had parked under a camera, he was told "it may not be on the car at that time. They're not really helpful. They don't help at all," he said.

Thieves can get under the vehicle and have the converter removed in a couple of minutes, he said.

"I'm straight out of university. I don't make a ton of money. It's not insured. The money comes out of my pocket," Mr. Djorsev said, adding GO is "the first to ticket you if you park illegally."

GO is "looking at" increasing staff at some stations to do more security work, said Gary McNeil, GO's managing director.

However, "very scarce resources" are preventing having more security staff.

"In order to have a high degree of security at those stations, you'd probably need about 10 people. Even if you've got a station attendant in a station with a CCTV (closed circuit television) camera, that's a very large area to monitor," he said.

About 350 incidents are reported to GO each year, but officials admit there is no formal reporting process, so the number could be higher.

"We have signs indicating to people to call through to Crime Stoppers if they have to. Around our stations we have signs advising people of our transit enforcement number," Mr. McNeil said.
