It was a tragic crash that took the life of two young girls and shook the community and nation.

On Saturday, almost one year since the horrific south London Costco crash, friends and family gathered together for a special charity event in honour of Addison Hall and her unborn sister who died in the hospital.

Hundreds of bikers came out to support the Bikes for Tikes Ride.

"I had a young niece die, so I know what it's like to have a death in the family of a young child and it's just a tragedy," says participant Ian Anderson.

"I see a lot of my friends here and I see a lot of their friends and it is just nice to see the community came out to support us," says organizer and uncle to the girls, Ruben Teves.

Addison Hall was 6 when she, her pregnant mother and 3 year old sister were struck by a vehicle at the entrance of the Wellington Road Costco.

Addison and her infant baby sister who was delivered via C-section died.

Her mother and three year old sister were seriously hurt but survived

"I feel like i lost my own kids. I just take it day by day. It's still very hard and I live with them in my mind every second of every day," says Sarah Teves, the girl's aunt.

Family members say this ride is in honour of baby Rhiannon and Addison who is being remembered as a vibrant and loving little girl.

"She loved being a big sister and she was so excited that she was going to have another little sister. And she will be dearly missed because she was just such a huge part of our lives," adds Teves.

All money raised through the ride will go towards the Children's Health Foundation.

Meantime, Ruth Burger, the woman convicted in the crash, will be sentenced on Oct. 20.

She was found guilty in June of two counts of dangerous driving causing death, and two counts of dangerous driving causing bodily harm.
