The company says Metro websites in Hamilton, Kitchener, London, Regina, Saskatoon, Victoria and Windsor will close down effective immediately.
The move comes after the Star Media Group, a division of Torstar, announced in July that it would shutter the Metro papers in Regina, Saskatoon and London, Ont., as it focused on areas of the country with the "greatest potential for Metro.''
All three of those cities had one reporter on staff, an editor in London and another to oversee both editions in Saskatchewan.
A message on the Metro website told readers that after experimenting with digital-only publications, it decided that the "results to date" led them to the decision.
Metro says it will continue to publish news stories online in the seven cities where it still distributes print editions: Halifax, Ottawa, Toronto, Winnipeg, Calgary, Edmonton and Vancouver.
