Transport Minister Marc Garneau is ordering his department to take a fresh look at the data on school bus safety and seatbelts.
Garneau says if seatbelts are properly used and installed on buses they can provide an additional layer of safety for riders, but notes that current seat designs already provide good safety in the event of an accident.
The government was put on the defensive Monday after an investigation from the CBC show ``The Fifth Estate'' suggested federal regulations about school bus safety restraints were based on out-of-date and incomplete information.
Canada doesn't currently require seatbelts on school buses, but did introduce new guidelines in late June to regulate their use by bus operators who choose to install them.
Those new technical requirements say restraints must not compromise existing safety features of the compartmentalized seats specifically designed to protect school children in the event of a crash.
A 2010 Transport Canada study says seatbelts could help prevent injuries in rollovers, crashes where a pickup truck or larger vehicle slammed into the side of a bus, or crashes causing ``significant vertical lift of the occupant compartment.''
