Milton GO line users will have to find alternative travel options for a second day in a row as train service will remain suspended on Friday despite the federal government's move to end the rail labour dispute.

A spokesperson for Metrolinx told CTV News Toronto that service was not resuming because it had not been informed by Canadian Pacific Kansas City Ltd. (CPKC), which owns the tracks, when traffic control operators affected by the work stoppage would return.

The spokesperson added that there's no way to run trains safely without the operators.

"We are aware of the announcement by Federal Labour Minister Steve MacKinnon and will communicate service impacts to our customers as more information becomes available," the Crown agency said in an emailed statement to CTV News Toronto.

There will also be no trains stopping at Hamilton GO station on Friday. No other lines on GO transit are impacted.

On Thursday, many commuters who usually use the Milton line were forced to look for other transit options after more than 9,000 rail workers were locked out by CPKC and the Canadian National Railway Co. (CN).

The union representing the workers and the companies were unable to reach an agreement before Thursday's 12:01 a.m. deadline, resulting in nationwide railway closures.

Less than 24 hours into the lockout, MacKinnon announced Thursday afternoon that he would ask the Canada Industrial Relations Board to order a return to work and to impose binding arbitration.

After MacKinnon's announcement, CN and CPKC confirmed they were preparing to restart operations.
