Is the Government of Canada planning to sell off more federal buildings?

Is that why public servants are being offered "alternative work hubs"?According to a June 3, 2019 Ottawa Citizen newspaper article:
     "The pilot project, called GCcoworking, is being spearheaded by Public Services and Procurement Canada and seeks to provide federal government employees with flexible workplaces separate from their regular offices or their homes." (From: "Federal government opens 2 of 5 alternative work hubs for public servants." by Kayla Douglas, Ottawa Citizen, June 3, 2019.)
 (Note: The Department of Public Works and Government Services is now known as Public Services and Procurement Canada.)
