Parks Canada workers at Fortress of Louisbourg in Cape Breton were told Monday that 10 people will lose their jobs, while another 110 will have their hours cut back, according to the union representing the workers.
Workers told CBC News they were shocked by the development. They said the season will be shortened to save money, although no further details were given.
Jeannie Baldwin, who represents the Atlantic region with the Public Service Alliance of Canada, said this will have a dramatic effect on the area.
"You're talking about a community that has an 18 per cent unemployment rate," she said.
"This does not bring growth into communities. What this is doing is devastating small communities."
The Fortress of Louisbourg National Historic Site of Canada is the largest employer in the community.
"They look after Canada's treasure. This is not what we elected a government to do," said Baldwin.
Other federal workers given notice
Baldwin said an additional 35 workers were given notice that their jobs will be affected by cuts at the Parks Canada service centre in Halifax.
In Amherst, 18 notices were handed out at Aboriginal Affairs and Northern Development Canada.
Baldwin said this is just the beginning of what will be a tough week for federal workers as more cuts are announced.
She said the public will see the impact of the cuts when they begin having to wait longer to receive federal support and have services delivered.
The Public Service Alliance of Canada says more than 1,100 employees in Atlantic Canada have been told so far that their jobs will be affected, with about 60 per cent of those workers being in Nova Scotia.
