The Transportation Safety Board (TSB) is investigating after a worker died on the job at the Canadian Pacific Railway yard in Côte Saint-Luc this morning.

In a statement, CP said it happened around 6:00 a.m.

"Our thoughts are with the employee's family and friends at this time. Out of respect for their privacy, we are not releasing additional details about the employee or the incident," the statement read.

The Teamsters union that represents over 16,000 employees who work in the rail industry, including CP, isn't releasing details either, but says it extends its condolences to the family and is following the investigation closely.

"When accidents like this do happen, it's really a tragedy and we want to work closely with all stakeholders, employers, coworkers, other Teamster members, Transportation Safety Board investigators to figure out what happened and how to make sure these events never happen again," said Christopher Monette, director of public affairs for Teamsters Canada.

The TSB confirmed in a statement that a team of investigators has been dispatched to the site to investigate a rail accident.
