Canadian Police say seven children have been injured and are being taken to the hospital after a tanker truck collided with a school bus northwest of Toronto.

Halton Regional Police said Thursday that all children on the bus are conscious and have been taken off the vehicle. Peel Region paramedics say two of the children have serious but non-life-threatening injuries.

Spokesman Brad Bowie says it appears that the tanker truck rear-ended the school bus on Thursday morning.
