Police helped Mr Williams to recover the car from the water near Pontcysyllte Aqueduct after its handbrake is believed to have failed, letting the car to roll down.
‘Someone came in and asked if I was the owner of a silver Toyota,’ Mr Williams explained.
‘They said it had rolled into the canal – it sort of ruined my day.’
The 30-year old said it marked the end of a bad week after learning he could lose his job.
‘I’ve had the worst luck this week – but I can see the funny side of my car rolling in to the canal – at least no one was hurt,’ he said.
