Tree Island Steel Ltd. (the "Company" or "Tree Island") (TSX:TSL) announced today that the Company has been served with a 72-hour strike notice from Teamsters Local Union No. 213 (the "Union") in relation to some of its operations at its facility in Richmond, British Columbia.

Tree Island has been in negotiations with the Union since May 2020 for a new collective agreement to replace the Company’s prior agreement with the Union. The prior collective agreement expired in June 2020 and covered approximately 240 of the Company’s hourly employees at its facility in Richmond, British Columbia.

"We remain committed to negotiating a mutually beneficial agreement with the Union that creates certainty for our employees, customers and other stakeholders while ensuring we remain globally competitive."

The Union will be voting on the latest collective agreement offer from the Company, with voting expected to close on October 14, 2020. The Union has advised the Company that it does not intend to commence a strike until after the vote. If the Company’s latest offer is rejected at the vote, the Union may strike beginning October 14, 2020.
