Whenever Dennis Wilson wants to take a drive in his new SUV, he has to set aside an extra 15 minutes. That’s about how long it takes to remove the car’s steering wheel club, undo four tire locks and lower a yellow bollard before backing out of his driveway.

His Honda CR-V is also fitted with two alarm systems, a vehicle tracking device and, for good measure, four Apple AirTags. Its remote-access key fob rests in a Faraday bag, to jam illicit unlocking signals.

As a final touch, he mounted two motion-sensitive floodlights on his house and aimed them at the driveway in his modest neighborhood in Toronto.

But all of these security gadgets, Mr. Wilson is convinced, will do no more than delay what seems inevitable: Toronto’s seasoned auto thieves won’t be deterred by the defensive gear, and they’ll make off with this Honda SUV just as they did with its predecessor — and its insurance replacement, which they returned to steal.

“By no means do I think that I’ve stopped them,” Mr. Wilson said. “All I’ve done is made it take an extra 10 minutes to steal my car.”
