CBC News has learned that a child involved in Friday's bus crash near Kingston Road was airlifted to Halifax.
The child is in "stable" condition, CBC News was told.
Friday afternoon, a Code Orange was cleared at the Queen Elizabeth Hospital after three children were treated there for injuries following the accident. Code Orange is called whenever a hospital expects to respond to a large influx of patients.
The three children were transferred to the hospital after Bus 49 flipped on its side. The province previously said that at least two of the children at the QEH "may have more serious injuries that may require more medical attention, but they are stable."
Before that, the Public Schools Branch had said only one child suffered "minor injuries," and that all other students on the bus were transported to East Wiltshire Intermediate School to be picked up by parents and guardians following the accident.
The PSB said Bus 49 serves students in the Bluefield family of schools. It said all students on board were from either Westwood Primary or Eliot River Elementary.
The principal at Westwood Primary said in an email that parents of students who had been injured were notified, and that other parents should monitor their children for unknown injuries or stress caused by the accident.
The accident happened near the intersection between Kingston Road and Bannockburn Road. The RCMP says the intersection, which had been closed following the accident, is now open again.
First responders and school personnel are on the site of the accident. The North River Fire Department and at least two ambulances were present.
There were also ambulances near the East Wiltshire school.
The PSB also said student services will be on site at the schools next week to talk through any concerns students may have.
RCMP issued a press release on Saturday saying the crash was the result of a collision between the bus and an SUV.
The release said the bus had 25 students on board.
The driver and the passenger in the SUV involved in the accident were not injured, the release said.
