Union presence in the warehousing sector

The unionization rate in the overall “Transportation and warehousing” industry classification is very high, sitting at 39.4% in 2020, almost 7% higher than the service sector average.* However, the transportation portion of that classification is heavily unionized, and that number is in no way representative of the unionization rate for the warehouse sector. According to a December 2020 media report on the abysmal working conditions in Amazon distribution centres in the Greater Toronto Area, the union density for the warehouse sector is actually 12%. This means union density in warehouses is 3% lower than the rate for the overall private sector.**

Unifor represents almost 7,000 warehouse workers in Canada. Of that total membership: approximately:

  • 57% of those members work in Ontario,
  • 24% work in Central and Western Canada,
  • 12% work in Quebec, and
  • 7% work in Eastern Canada.

Unifor warehouse members work for both third-party logistics companies as well as warehouse operations for companies in other sectors, and major employers include:

  • DHL Express
  • Loomis Express
  • Tracker Logistics Inc.
  • Sysco Food Services
  • Martin-Brower of Canada
  • Loblaws Companies Ltd
  • Metro Inc.
  • Sobeys Inc.
  • Atlantic Wholesaler Ltd.
  • Ford Motor Company
  • General Motors
  • Uni-Select
  • Groupe ATBM
  • Penske Logistics
