Fire officials in Ottawa also said at least a dozen people were injured, CTV reported.
“We had bodies and debris pretty much everywhere at the impact site,” Ottawa Fire Service’s Marc Messier told CTV’s News Channel.
“It’s definitely a serious scene,” he said. “Our top priority is getting anyone with serious injuries to the hospital and getting them into proper care.”
The crash happened at 8:48 a.m., the networks reported. CTV said a Via Rail train at Woodroffe Avenue and Fallowfield Road hit an Ottawa Carlton Transit city bus.
The train derailed “approximately 100 to 200 feet down the rail,” Messier said, and all of the casualties were on the bus.
