TORONTO -- The Canadian retail sector was already in trouble before COVID-19, but the pandemic has left it on even shakier ground.

The combination of forced closures, decreased consumer spending and limited rent relief measures has left some retailers unable to maintain their existing operations.

Here is a look at some of the major retail closures announced in Canada in 2020, both before and during the pandemic.

Scholar’s Choice: The educational toys and teaching materials retailer announced on July 10 it was closing 13 stores across the country. Only three stores will remain open – London, Ont., Winnipeg and Moncton – and act as regional sales and distribution centres. Scholar’s Choice also filed for creditor protection through a notice of intention to propose a reorganization plan to restructure the company.

DavidsTea: The Montreal-based beverage retailer announced on July 9 that it was closing 82 of its locations in Canada and all 42 of its U.S. stores to focus more on its e-commerce business and supplying grocery stores and pharmacies. The company, which also filed for creditor protection, said it was closing shops that were unprofitable and that it hoped to negotiate more favourable lease terms for the 100 remaining locations in Canada. The company said COVID-19 pandemic had worsened an already challenging retail market.

Microsoft: The technology company revealed on June 26 that it would be closing nearly all of its 83 physical stores around the world as part of a “strategic change” for its retail business.

Bestseller Canada: The company that operates Jack & Jones and Vero Moda filed for creditor protection June 2.
