Tim Hortons Cafe & Bake Shop has closed numerous stores across central Maine as well as in New York this week in the latest reorganization for the Toronto-based coffee shop chain.

The chain abruptly closed two stores in South Portland – at the Maine Mall and on Market Street – as well as one on Western Avenue in Augusta, prompting the Maine Department of Labor to activate the agency’s Rapid Response Team to assist workers displaced by the closures. Additionally, three Tim Hortons stores in the Lewiston-Auburn area were closed on Wednesday, according to the Lewiston Sun Journal.

It was unclear Wednesday evening whether more Tim Hortons locations in Maine had shuttered or were facing closure. A spokeswoman for the company, which has been rapidly expanding in the U.S. in recent years, did not answer questions about the number of stores slated for closure in Maine.

“In line with our vision to deliver a great guest experience while building and strengthening the Tim Hortons brand, we continuously review the performance of our restaurants,” Tim Hortons spokeswoman Jodi Bond said in a statement. “As we build the foundation for accelerated growth in the U.S., we have decided to close some restaurants in New York and Maine. We are supporting our restaurant owners in their transition and remain excited about the opportunities to expand the iconic Tim Hortons brand in the U.S.”

The company also closed at least seven stores in the Syracuse, New York, area, according to The Post-Standard newspaper in Syracuse.

This is not the first time Tim Hortons has closed locations in Maine. In 2013, the chain closed six shops as the company – which is Canada’s largest coffee provider – said it was reconsidering its New England strategy.

It was unclear how many Maine employees were affected by the closures.

The Maine Department of Labor’s Rapid Response program planned to hold two sessions for displaced employees: on Monday, Nov. 23 from 1 to 2 p.m. at the Augusta CareerCenter and on Tuesday, Nov. 24 at 9 a.m. at the Greater Portland CareerCenter. The sessions are designed to advise and assist employees affected by the closures.
