A man charged with impaired driving in connection with the death of a 24-year-old personal trainer must spend at least one more night in jail after a judge denied him bail Wednesday.

Oliver Karafa, 19, will appear in court again Thursday.

A memorial formed overnight at the site of the crash, which left the luxury SUV torn to pieces.

Flowers and letters of condolence collected en masse on Mount Pleasant Road, near Sheldrake Boulevard, where a Range Rover smashed into a pole early Tuesday.

David Chiang, the 24-year-old passenger of the vehicle, was killed instantly.

The 19-year-old driver is facing a variety of charges, including criminal negligence, impaired driving and dangerous driving.

Chiang was a personal trainer who trained the driver at Extreme Fitness.

Members of the gym were at a loss for words on Wednesday as they struggled to cope with the death.

One man described Chiang as a dedicated trainer who managed to get the best out of his clients.

David Luck, the gym's general manager, told CTV Toronto that the loss would stretch beyond the workplace.

"He was a friend to all of us, more than just a co-worker. He was a great friend. A lot of us are shaken," Luck said.

Oliver Karafa, of Toronto, is expected to appear in a Toronto court for a bail hearing on Wednesday.

Natalia Richtie, who lives across the street from the crash site, was among those who placed flowers at the scene.

She said the crash sounded like a plane crash.

Richtie said she came out of her house at about 2:30 a.m. to see the driver standing by the smashed up wreckage of the car.

Following the collision on Tuesday, pieces of debris were left scattered more than 100 metres from the impact.

One end of the vehicle was left wrapped around the pole, while the other was flung across the road to the other side of the street.

Estimates suggest the Ranger Rover would need to be travelling between 150 and 180 km/h to cause the amount of carnage left at the scene -- three times faster than the posted speed limit.
