MONTREAL — The Transportation Safety Board of Canada says it has deployed a team northeast of Montreal to investigate after 45 railcars with a CN train derailed in a residential area on Sunday.

Police in Repentigny, Que., say no injuries were reported and nothing had spilled from the railcars.

Hugo Fontaine, spokesperson for the safety board, says two investigators arrived at the scene of the derailment on Sunday to gather information and assess what happened.

CN Rail says none of the railcars contained hazardous materials, adding that it would issue an update on the derailment later.
