She said her daughter developed tremendous pain immediately after undergoing the procedure.
'She couldn't take it anymore...she couldn't even go to the bathroom alone. She needed help with everything,'' the Toronto Star newspaper quoted her as saying at the hearing.
She said when she examined her daughter she found that one of her breasts had become dramatically enlarged.
She said her daughter grew pale and cold and 'fainted'' in her arms. The woman said she rushed her to hospital to be treated by a plastic surgeon.
Twenty-eight other women have also made allegations of mistreatment against the same woman surgeon who botched up this procedure.
She faces ban from her profession if found guilty.
