GO train commuters could face delays Wednesday after electrical workers at Union Station left work at midnight.

The 95 employees of Toronto Terminals Railway (TTR) at the transit hub went on strike beginning at 12:01 a.m. Wednesday.

“We have been advised that members of the TTR union are now officially on strike,” Metrolinx spokeswoman Anne Marie Aikins said in a statement provided to CityNews.

“The labor disruption contingency plan is in effect and we continue to hope that the impact on GO and UP Express services will be limited. We will communicate frequently with our customers to keep them informed in the event of delays or cancellations.

Striking employees are responsible for signaling and maintaining communications at the station. They also manage train control in the Union Station Rail Corridor.

Ahead of Tuesday’s strike, Aikins predicted that passengers could experience 10-15 minute delays and that several train journeys during morning and afternoon peaks could be cancelled. She says Metrolinx will keep customers informed if there are any delays or cancellations affecting GO Transit or UP Express trips.

The strike is not expected to affect TTC subway service in any way.

The workers are members of the International Brotherhood of Electrical Workers union and have been without a contract since December 2019. TTR says wages have been a contentious point during negotiations.

Union Station is the busiest passenger transportation hub in Canada, with approximately 200,000 GO Train commuters passing through it every day.
