The five-year-old boy is one of three children still in critical condition at the Alberta Children's Hospital, while six other children are listed as being in non-life threatening condition.
The female bus driver, who had at least two children on the bus at the time of the crash, was also taken to hospital but there has been no word on her condition.
The crash happened just after 8 a.m. MT on Friday near Crossfield, Alta., which is roughly a 40-minute drive northeast of Calgary.
All of the nine children who were injured either attended Crossfield Elementary School or WG Murdoch School in Crossfield, part of the Rocky Mountain School Division.
Crossfield Mayor Nathan Anderson is scheduled to visit the injured children Saturday in hospital.
